Brass Choir music
I did a few arrangements for a brass choir I was in back in 2007. I can post two of them here because the originals are easily old enough to be public domain. These are early attempts at arranging and probably shouldn’t be taken as indicative of current efforts!
Gymnopédie No. 1 by Erik Satie (available at Score Exchange). This is written for three B♭ trumpets, horn, trombone, and tuba.
“O Isis und Osiris” from Die Zauberflöte by Wolfgang Amadeus Mozart (available at Score Exchange). This is written for two B♭ trumpets, horn, trombone, solo tuba, and another tuba, although I included an alternate part for a second trombone in case the second tuba isn’t available.
Brass Quintet music
Adagio (K.411/K6.484a), originally for two clarinets and three basset horns, by Wolfgang Amadeus Mozart (available at Score Exchange). Trumpets are in E♭ and B♭.
“Bist du bei mir” from Diomedes by Gottfried Heinrich Stölzel (available at Score Exchange). Standard instrumentation.
Kyrie (K.89/K6.73k), a canon for five equal voices, originally for sopranos, by Wolfgang Amadeus Mozart (available at Score Exchange). Trumpets are both in C. There is some fantastic counterpoint in this piece, and I did my best to capture it authentically while adjusting for the ranges of the various instruments in a quintet.
“O mio babbino caro” from Gianni Schicchi by Giacomo Puccini (available at Score Exchange). This is a simple arrangement featuring one of the trumpets (both in B♭ here) as the soprano soloist.
Trombone Choir music
“Christus factus est” by Anton Bruckner (available at Score Exchange). This is in four parts: alto/tenor/tenor/bass, although a sufficiently strong player could go without the alto if one isn’t available.
