Compositions and Arrangements for Accordion Orchestra

Latest change, November 4, 2019: Added "Chanson de Printemps" (Frühlingslied)from Lieder ohne Worte, opus 62 by Mendelssohn, in arrangement for quartet.

Total number of downloads is currently already over 25.000.
(This excludes downloads by myself and it does not count both score and parts of the same piece, nor repeated requests. But some "robots" may be hard to detect so some downloads may not be by real people.)

I arrange music for different accordion orchestras and make sheet music of arrangements freely available for download (as pdf) as a service to the accordion community. Occasionally I also compose something myself, mostly inspired by some "old masters". Many of my arrangements were initially created for Avanti, a small accordion orchestra in Antwerp (Belgium) I have led for about 30 years and that has (unfortunately) stopped its activities in 2014. Some arrangements are for larger orchestra and were made for Accordeana in Helmond or for the Nederlands Symfonisch Accordeon Orkest. Some of the arrangements for quintet have been made for ARTE, an accordion quintet started in 2013 in the Eindhoven region, or for Kwintissimo, an accordion quintet started in 2016 with players from all over the Netherlands. For some pieces there is a recording by the virtual quintet Professor P.

If you are going to study and perform one of my arrangements (or download it for any other purpose) please send me an email (to debra at win.tue.nl). When I have your email I can let you know about possible small errors I find in an arrangement and when you find an error please also let me know so I can notify everyone else who uses the arrangement. (An invitation to a concert would be appreciated even more, especially if it's not too far away.)
Better still is that when you finally master a new piece, post it on YouTube (and don't forget to mention me as arranger so that when I simply search for my name I can find all these performances)!

Most arrangements assume that the orchestra has at least 5 players (4 accordion + 1 basson accordion) and if there is percussion it is written to be played by 1 person. Some arrangements assume at least 6 players and some can be done with just 4.

The compositions and the arrangements that I made from Public Domain music are not only available here but also on IMSLP, the Petrucci Music Library of (mostly old) music that is in the public domain. My arrangements and compositions have a Creative Commons Attribution license meaning you can use them as long as you mention my name. You can adapt my arrangements for a different orchestra too as long as you keep mentioning my name as your source.

The compositions are ordered alphabetically by composer (and then title for multiple pieces by the same composer).

Recordings of Public Domain music are available directly from this site. Recordings of still copyrighted music are available through YouTube (so YouTube pays the fees to the rights holders). For each recording it is indicated who plays the music.

Il Postino, L. Bacalov

This arrangement has a nice solo part which is best played either on an accordina, harmonica or bandoneon to create a sound that is more distinct from the other parts.

Bist du bei mir, J.S. Bach / G.H. Stölzel, BWV 508

This song (also known as "Komm süsser Tod") from the "Notenbüchlein der Anna magdalena Bach" has been arranged for quintet by adding parts that do not exist at all in the original. (I actually could not find this song in my version of that Notenbüchlein.) The melody was originally from Gottfried Heinrich Stölzel, and arranged (orchestrated) by Bach.
The fourth voice can easily be omitted for a performance with quartet. There is a duo arrangement from which the second line mostly combines what was second and third so it's possible to combine different bits to play it with three people as well. And finally, there is a duo arrangement in F that enables the bass line to be played an octave lower (as it then only goes down to E). This however requires a high Bes in the first voice (unless played in different register in loco).

Adagio from Prelude, Adagio and Fugue for organ, J.S. Bach, BWV 564

This slow piece was featured in (the last episode of season 2 of) the Belgian TV series "Professor T" (or just "T" for short). There are two versions here: one for quintet and one for duo. The quintet version also contains a 4+bass part so a quartet of accordions can play this (but the 4+bass requires melody bass). The piece is very slow and to make it easier to read the duo version is also available using double note values.
Note: the quintet version can be played as quartet by leaving out acc. 4 which yields almost exactly the organ version, or as trio by also combining acc. 2 and 3.
Note: the duo version is for one solo instrument (only right hand) and one accordion with melody bass (convertor or MIII).

Wachet auf, ruft uns die Stimme, Philipp Nicolai and J.S. Bach, BWV 645

This choral by Philipp Nicolai (composed in 1599) has been arranged for organ by Bach as BWV 645, or for violins, voice and continuo as BWV 140. The new arrangement is for 3 accordions and bass, but can also easily be played by a quintet by doubling the first voice..

Duo-Concerto in D Minor, part 1, J.S. Bach, BWV 1043

This piece is rather difficult, including the basson accordion part. (The live recording was done by Accordeana in a church, with a lot of echo.) There is no percussion part.
Download:
parts, score, live recording by Accordeana.

Duo-Concerto in D Minor, part 2, J.S. Bach, BWV 1043

This piece is best played by 6 or 7 players as parts III and IV divided in an upper and lower sub-part. The score has these combined but in the parts file the separate sub-parts are included as well. It is possible to play this with 5 players but it is easier with at least 6. This wonderful composition needs to be played with a lot of passion. There is no percussion part.

Erbarme Dich, from the Mattheus Passion, J.S. Bach, BWV 244

This is the most famous part of the Mattheus Passion, arranged in 7 parts (2 solo parts, 4 normal parts plus base).

Concerto for Oboe d'amore in A major, J.S. Bach, BWV 1055R, first movement

This piece for Oboe d'amore (goes a bit lower than a normal oboe) and strings has been arranged for quintet. If the first voice is played by oboe d'amore, it may need to be transposed for the player to read it. The arrangement is written in concert pitch so as to be ready for accordion quintet. The only part that really deviates from the original is the fourth voice: this is the viola part with lots of stuff added to also form the continuo part. This arrangement covers only the first movement.

Orchestral Suite nr. 2, J.S. Bach, BWV 1067, Menuet and Badinerie

Menuet and Badinerie are the last two movements of BWV 1067, and probably also the most famous two movements. In the quintet arrangement the Menuet has a real continuo part (4rd voice) but Badinerie does not (and does not really need it). The Menuet is relatively easy, compared to Badinerie. It is best to use a clearly distinct instrument for the solo parts. The accordina may be a good choice for that, but a non-cassotto register may also do well.
To get a good impression of what this sounds like, we have a
recording by Professor P.

Orchestral Suite nr. 3, J.S. Bach, BWV 1068

This is the suite containing the famous Air. It is for accordion orchestra. Especially the 4rd voice is a bit hard to play solo, making it hard to do this with quintet (but not impossible). There is a Timpani part as well, like in the original.
To show what the Air from this arrangement sounds like,
Professor P provided a recording.
Download: parts, score, MuseScore source (5 files in zip).

Air from the Suite for Orchestra, J.S. Bach, BWV 1068

While working on an arrangement of the whole suite I made a version of Air for two accordions, using standard bass in the accompaniment. The second part is best played on a button accordion because of large distances (but it can be done on piano accordion with large hands).

Gavotte from the Suite for Orchestra, J.S. Bach, BWV 1068

This is a movement from the suite, arranged in only 4 voices (3 accordions plus base) many years ago already.

Harpsichord Concerto No.5 in F minor, Arioso (Largo), J.S. Bach, BWV 1056

This slow piece is best played by a quintet, one player for each voice. It is very challenging to combine the solo first voice with nice melody with the "plucked" notes in other voices, and the softer but unique continuo voice (fourth voice).
ARTE made a recording for their CD "Van ARTE".
Download: parts, score.

Partita 2 (Sinfonia) BWV 826, J.S. Bach

This piece has an interesting third part which is difficult for all voices. I got the inspiration for this piece after hearing a performance by the Pawel Smirnov orchestra.
Note that the original has all notes of half the value of this arrangement. That makes for lots of 1/32 notes and some 1/64 notes and is hard to read, so that's why I changed it all.

Sheep May Safely Graze, BWV 208, J.S. Bach

This is a straightforward arrangement for quintet. I recorded it in 2005 already.

Violin Concerto no. 1 (BWV 1041 and 1058), first movement, J.S. Bach

BWV 1041 is Johann Sebastian's Bach's first violin concerto (in A minor) and BWV 1058 is the seventh Harpsichord concerto (in G minor). They are in fact the same composition, for a different ensemble. I made one arrangement out of both, mainly BWV 1041, with bits of 1058 added, mostly as part of the continuo part (4rd voice). I made a version for accordion quintet and one for either sextet or orchestra with a solo part.

Violin Concerto (BWV 1042 and 1054), first movement, J.S. Bach

BWV 1042 is a violin concerto in E and BWV 1054 is a piano concerto in D. I made one arrangement out of both (which are almost identical anyway). There is no percussion part.
Download version in D:
parts, score live recording, played by accordion orchestra Esmeralda, with violin for the solo. Played in a church with a lot of echo. If you really wish to perform this with a violin solo it is better to this version in E (easier for the violinist): parts, score

Violin Concerto (BWV 1042), third movement, J.S. Bach

Years after arranging the first movement I decided to also make an arrangement of the third movement: Allegro assai. This again is for quintet or orchestra. The first voice is solo.

Concerto for Oboe and Violin (BWV 1060R), J.S. Bach

BWV 1060 is a concerto for 2 harpsichords (and strings) and has been reworked into BWV 1060R for Oboe and Violin, which turned out to be much more popular. I made an arrangement of 1060R where I made it richer not just be adding the continuo part but also by inserting bits from 1060 that were removed in 1060R. The three parts (allegro, adagio, allegro) are placed in separate files as I expect most ensembles to select just one of the three movements. (The second movement is not too difficult, the first and third are quite challenging.)

Jesus bleibet meine Freude (BWV 147), J.S. Bach

This choral is a part of Cantata BWV 147. The arrangement is for quintet, but also suitable for a larger ensemble (to allow for "diviso"). The main theme is for soprano and trumpet, hence the registration.

Sei Lob und Preis mit Ehren (BWV 167), J.S. Bach

This is the choral from BWV 167, made famous by Yo-Yo Ma (see and hear it on YouTube). The arrangement is fairly straightforward except for a few alterations and a completely made--up continuo part. The first, fourth and basson parts are fairly difficult, the second and third voice are easy. Good for a mixed orchestra.

This is the second part of Jesu, der du meine Seele. It has been arranged for 6 parts. Watch on YouTube

Adagio for Strings, S. Barber

Adagio for Strings is a challenge because it is so slow. I made the arrangement in 2004 for Avanti, and now converted it to MuseScore, and made a small correction too. Note that this is not yet public domain (until 2032 or 2052 depending on your country's legislation).

Hirtengesang (Symphony nr. 6, movement 5), L.v. Beethoven

Hirtengesang ("Frohe und dankbare Gefühle nach dem Sturm") is the final movement of Ludwig van Beethoven's Symphony nr. 6. The arrangement for accordion quintet or orchestra is an abridged version (just over 4 minutes instead of 9) and shows an interesting contrast between a very difficult first voice (lots of ricochet with large chords) and relatively easy other voices, especially when using diviso.

Professor P made a recording available.

Casta Diva from the opera Norma, V. Bellini

Casta Diva is one of the better-known songs from the opera Norma by Vincenzo Bellini. The arrangement is for quintet, where for a few measures the third voice needs to also use a few easy bass notes/chords.

Entr'Acte from Carmen, G. Bizet

The Entr'Acte between Act II and Act III has been made popular by famous accordion player Ksenija Sidorova who renamed this to "Sunrise over Seville". The arrangement is for quintet (plus optional timpani) but can easily also be played by quartet (there is a combined 4+B part). There is also a duo version.
This piece is in the key of Es major and requires a high Bes in the first voice. To make it playable by musicians lacking that high Bes (but having A like most piano accordions do) I have also included a transposition to the key of D major.

Notturno from the Second String Quartet, A. Borodin

This is a well-known piece by Alexander Borodin. Because of the difference in range between (standard) accordions and a viola and cello the string quartet has been arranged for accordion quintet. It sounds deceptively easy, but in fact there are some interesting challenges: the melody transposes all the time (for which I introduced key changes where the original just uses loads of accidentals), there is some very long fast bellow shake and tremolando which is difficult to keep up without weakening after a while.
To give an impression of what this sounds like
Professor P made a recording.
Because this piece is both long and difficult (near the end) I also created an abridged version (5:00 instead of 7:20) which omits the difficult part with all the below shake and tremolando. To give an impression of what this version sounds like Professor P made a recording. (Actually this is "remixed" from the recording of the full version.)

Sugar (De Fabriek), R. Bos

This is the main theme of the TV series "De Fabriek" that was very popular in the eighties in the Netherlands. It is best suited for a large accordion orchestra (first voice requires at least 3 players, second voice at least 2).
This arrangement has been performed by the "Accordeonvereniging Aeolus" (Spankeren, Dieren, the Netherlands) and they published the
recording on YouTube.
Download: parts, score.

Ave Cello, P. De Bra

This is my first "serious" own composition. It is based on Cello Suite nr. 1 by Bach (BWV 1007) and the Ave Maria by Gounod. Gounod wrote the Avé Maria on a different work by Bach. The Cello Suite is normally for unaccompanied cello, and I have once performed it on the basson accordion (after transposing it down a bit). Here it is transformed to a swinging song for 5 players: 3 accordions, one percussion player which can actually also be done on accordion and then the basson.
We have two recordings: a
live recording by ARTE (with percussion done on cajon) and a studio recording by Professor P (with percussion done on djembé).
Download: parts, score.

Rockalise, P. De Bra and S. Rachmaninoff

My second composition: a rock and swing number using the composition Vocalise by Serge Rachmaninoff. Vocalise is a long slow piece, hard to make this sound interesting with an accordion ensemble. But by turning it into a rock and swing piece it gets a completely new twist. The composition/arrangement is for accordion orchestra, including drums, but it can also be played by a quintet. To make this easier for an accordion orchestra divided parts 2 and 3 (2a, 2b, 3a, 3b) are included.
To make it easier to imagine what this may sound like there is a

Symphony nr. 3 opus 90, third movement, J. Brahms

The third movement of Symphony nr. 3 opus 90 by Johannes Brahms is a nice orchestra work, reduced to five parts (for quintet) and also reduced in time a bit. The first voice requires a high Bes. The third part can use the high C but can be played without. As for the bass accordion, the whole range of 40 notes is used when available.

Tangled Up, G. Chambers, V. Degiorgio, D. Schreurs

This was the first major hit of Caro Emerald. I arranged it for sextet, and we once performed it with a singer during an accordion weekend in Ouddorp (Zeeland). This composition I consider still way too recent to make an arrangement available for direct download. But if you want to try it, let me know.

Introduction from Concerto for Oboe and Strings, D. Cimarosa

The Concerto for Oboe and Strings is a combination of melodies written by Domenico Cimarosa. Arthur Benjamin compiled the Concerto (around 1942). The first part is "Introduction". The arrangement has a different ending because the original only leads up to the second movement and cannot really be used as an ending.
The arrangement is made for quintet, but it is possible to also play this piece with just two accordions, albeit both using both sides (one with melody bass) and the registration has to be adapted to create an acceptable balance. The quintet version is rather easy, the duo version is rather difficult.

Humoresque nr. 7 (opus 101), A. Dvorak

This is the best known Humoreque from the series of 8. The arrangement has been transposed to G (original is in Ges) and written in 4/4 instead of 2/4 (4/8) to make it more readable. The arrangement is written for 2 accordions and for 5 accordions. By combining parts from both you can also do 3 or 4 accordions.

Waltz from Serenade Opus 22, A. Dvorak

This waltz by Antonin Dvorak immediately sounds familiar (and may remind you of similar work by Tchaikovsky). It sounds deceptively simple but is actually quite difficult to play. It is a joy to listen to though. The arrangement is for quintet but an orchestra can divide parts to make it a bit less difficult to play.

Enigma Variations: Nimrod, E. Elgar

Nimrod is Variation IX (Adagio) from the Enigma Variations by Edward Elgar. The arrangement is for large accordion orchestra (8 accordion parts, bass, timpani). It is best when the first voice (1a) can reach high C (but this can be avoided through a register change).

Spleen, R. Galliano

This is an easy piece (except for the solo), for a small accordion group with solo on accordina.

Tango pour Claude, R. Galliano

This tango has been made "interesting" through a somewhat difficult solo part (inspired by different virtuoso performances found online) and a moderately difficult bass part. The solo requires high notes typically only found on button accordions.
There is also a "joke" inside: at some point someone should stand up and play four measures from Libertango and then be reprimanded by the conductor while the orchestra continues playing. (That is part III-solo.)

Adagio for Strings and Organ in G minor, T. Albinoni / R. Giazotto

The famous "Adagio by Albinoni" is actually a composition by Remo Giazotto. The composer claimed to have found a few measures and fragments of a continuo part in the Saksen state library, but this might not even be true. This Adagio is the most famous composition by Albinoni, and is not actually composed by Albinoni... It was composed in 1949. (The composer died in 1998 so this piece is not yet in the public domain.) The arrangement is for accordion quintet, where the fourth voice requires the use of melody bass. (Playing this with an orchestra with two bass accordions is actually easier to do.)
Professor P has made a recording (posted on YouTube) where the fourth voice is played on bayan with melody bass, but in diviso (which allows for a clearer pizzicato).

String Quartet 5(3), Ph. Glass

The third movement of Philip Glass' 5th string quartet is a good opportunity to become acquainted with minimal music and to learn to appreciate this style. I made an arrangement for accordion quintet (a quintet is better suited for this string quartet because of the range of the instruments).

Ecce Homo Qui Est Faba

To many people this title may mean nothing, and the religiously sounding melody may not ring a bell either, but this piece is the theme song of the mister Bean series (and the title translates to "Behold the man who is a bean"). The arrangement consists of a quintet version that has an extra repeat built into it (otherwise it is a very short piece), and a duo version (that does not have the extra repeat). The duo version requires melody bass.
Beware: this piece is not in the public domain (for a long time to come), but I am publishing it as many other arrangements can be found publicly online as well so I assume the rights holders will tolerate it. The composer is Howard Goodall.

Holberg Suite (1,2,5), E. Grieg

Solvejgs Song, from Peer Gynt Suite nr. 2, opus 55, E. Grieg

Solvejgs Song is part 4 of Peer Gynt Suite nr. 2 by Edvard Grieg. The arrangement is for accordion orchestra or quintet, and there is also a duo version. This is a very well known nice song, and it is technically rather easy. Note, The 3rd voice may use a high C (once) and the 4rd voice may use a low E (once). Both can be avoided.

Wedding day in Troldhaugen, E. Grieg

Wedding day in Troldhaugen, part 6 from the Lyrische Stücke opus 65 by Edward Grieg, is an uplifting piece, with a very happy part and a very lyric part. It was composed for (solo) piano. While it is very difficult on the piano I made an arrangement for accordion quintet that is not so difficult. Some tricky bits (like quintuples) have been simplified without being noticeable.

Aria "Lascia ch'io Piange" from Rinaldo, G.F. Handel

Sarabande, from Harpsichord Suite HWV 437, G.F. Handel

This is the most famous Sarabande by George Friedrich Handel. It is from a Harpsichord Suite, but now arranged for quartet or quintet and for duo. The quartet/quintet arrangement has a diviso making it sound differently with quartet versus with quintet, but the notes are the same. There are two versions of the duo arrangements: the "standard" one has a part that requires good melody-bass skills; the "bayan" version has that part moved to the treble side, but it requires the low range of a bayan keyboard.
Note: the duo version has been transposed from D minor to E minor because most accordions have melody bass going down only to E (not to D).

The Arrival of the Queen of Sheba, G.F. Handel

This famous part from the Oratorium Solomon by Handel is very well suited for an accordion orchestra, but it can be done with a quintet and the score indicates how to do so. The score and parts also contain lots of hints on how to play the piece (like which notes to make shorter and which longer). The second and third voice have been indicated as a bit louder than the other voices, not because they should sound louder but because they use one reed whereas all other voices play on two reeds. (Accordion players tend to forget to compensate for the number of reeds they play.) As with the original there is no percussion part.

Largo from Xerxes (Ombra mai fù), G.F. Handel

This piece is mostly known as the "Largo by Handel", but actually is the song "Ombra mai fù" (There is never shade) from Scene 1 of Act 1 of the Opera Xerxes. Most performances (and all performances I know of by accordion ensemble) ignore the existence of a continuo part, resulting in a rather boring slow piece. The continuo really livens it up.
First of all there is an arrangement for duo (two accordions or one accordion and some other solo instrument). This does not have a continuo part, sorry.
Then there is the quintet arrangement. By omitting the continuo part (acc. 4) this can be played by a quartet, and by dividing the third part it can be played by a sextet (or larger orchestra). A divided third part is included. By adding the continuo part (acc. 4) to the duo version a trio version is obtained.

The Water Music, selection of pieces from the first suite, G.F. Handel

The Water Music by Handel is a series of suites, of which nobody knows for certain what was intended to go where and where the music was performed in Handel's time. The first suite, HWV 348, is a Horn suite in F major. As it is rather long this arrangement consists of a selection of 5 pieces: Introduction (1), Allegro (3), Air (6), Bourrée (8) and "Alla Hornpipe" (12F), the latter of which is supposedly an early version of what became a Hornpipe in the second suite (HWV 349). There are 5 voices, but some division is needed, at least in the first voice, and probably also in other voices in order for the register changes to work out.
To get an impression of what this arrangement sounds like
Professor P made a recording, showing this selection takes just over 11 minutes, with the suggested omission of repeats.

Trumpet Concerto in Es, second movement, J. Haydn

The second movement (Andante) of the Trumpet Concerto in Es by Joseph Haydn is actually written in As (so no, I did not transpose it). It should be played very "cantabile". The arrangement is for quintet or orchestra. (There are some "div." indications which obviously do not apply to a quintet.)

Waltz from Masquerade (Maskerade), A. Khatchaturian

I arranged this famous waltz by Aram Khachaturian for Accordeana in 2014. This arrangement is for accordion orchestra, with 7 accordion parts (plus drums). The parts IIb and IIIb are easier than the other parts, to accommodate an orchestra with wildly varying experience levels. The first voice requires the use of high notes (like on accordions with 45 notes).

España Cañí, P. Marquina

España Cañí is the most famous composition by Pascual Marquina Narro and has always been associated with bull fights (even though the title refers to a spanish gypsy, no bull fight. The arrangement is for quintet. Not as difficult to play as it sounds. I have added a duo version. The first voice of this version can be used (as it has basses written out) to enable a trio to play this piece. There is also a 4+bass file that can be used by a quartet wanting to play this piece.
Note that the composer died on July 13, 1948, so this composition has entered the public domain on January 1, 2019 and can thus be performed without paying royalties to any rights collecting body. (The USA may be an exception as it has complex copyright laws to protect work since 1923, regardless of when the composer died.)

Intermezzo from Cavalleria Rusticana, P. Mascagni

The Intermezzo is the best known movement from Cavalleria Rusticana by Pietro Mascagni. The arrangement for duo is not all that easy to play (uses melody bass on one accordion and chords (without base notes) on the other one), but the quintet version is easy.

Meditation (from Thaïs), J. Massenet

This most well-known part from Thaïs has been arranged for quintet plus optional timpani. It is best if the second voice has a low E, but the arrangement shows how the third voice can compensate for that. There are some basses in the third voice (can only be done on the keyboard of very large button accordions). The first voice corresponds to the violin and second and third are harp parts. Be careful to not overpower the first voice.

Chanson de Printemps (Frühlingslied), F. Mendelssohn

The last song from the Lieder ohne Worte, opus 62, by Felix Mendelssohn Bartholdy is called "Frühlingslied" or "Chanson de Printemps" or "Spring Song". It is originally written for piano solo which makes it a challenge to replicate it on the accordion. The bass notes should all decay and the chords in the second and third voice were originally grace notes preceding the main note, but by use of the pedal on the piano they sound like arpeggio chords, except that the last note of the arpeggio is the main note and should be on the beat and should be the loudest of the whole chord. The arrangement is for quartet (3 accordions plus bass).

Czardas, V. Monti

The famous Czardas has been performed on accordion, solo, by many artists. But as it is a piece for violin solo and orchestra it is also very suitable as an orchestra piece. The arrangement is for accordion orchestra, with timpani for percussion (but it can also be played without percussion). There are just the standard 4 voices plus bass but diviso suggests it is easier to do with a larger group (although the solo obviously never becomes easy).

This is a rare arrangement I made for solo accordion. It is a combination of two songs from the Dutch movie "Turks Fruit", music by the brilliant dutch composer Rogier van Otterloo.

Adios Nonino, Astor Piazzolla

There are many arrangements of Adios Nonino, but the population of the Netherlands was completely baffled and moved by Carel Kraayenhof's performance at the wedding of Willem-Alexander and Maxima (currently King and Queen of the Netherlands).

But if you are interested in performing it, please let me know.

Rondeau from the Abdelazer Suite, Henry Purcell

This is the short and famous "Rondeau" by Purcell. The arrangement is for accordion quintet, but the fourth voice (the continuo) can also be omitted in order to play it with a quartet. There is also a transcription for two accordions (second one with melody bass). This misses the continuo, so that can be taken from the other arrangement when playing with 3 accordions. A quartet can also take the right hand from the duo arrangement to play 1, 2-3, 4 and bass, but a more advanced quartet can use the 2+3 part to play 1, 2+3, 4, bass.

Pavane Pour Une Infante Défunte, Maurice Ravel

This Pavane (slow Spanish dance) written for "small orchestra" was a real challenge to reduce to 5 voices. It is possible to play this with a quintet (preferably with some button accordions) but is better suited for larger accordion orchestra (so "diviso" can actually be done and register switches become easier). It is somewhat modern (violates classical harmony rules) but still sounds quite harmonious.

Le Quattro Stagioni: Autunno, A. Vivaldi (RV 293)

Autunno, or the autumn (fall) is a very happy season from Le Quattro Stagioni by Antonio Vivaldi. The first movement is all about singing and dancing and drinking (and getting drunk), presumably to celebrate the harvest. In the second movement the drunks are asleep. The third movement expresses a hunting party, chasing prey with dogs and guns and eventually killing the prey and celebrating. The arrangement is for accordion orchestra, consisting of a solo part and then 4 accordion parts and bass, but the accordion parts have solo and tutti sections, so to distinguish clearly between them you need at least 10 players in the orchestra.
