Trio Op.87 Despite the Opus number of 87 this was composed in 1794, before Beethoven had published his Opus 1. It was originally composed for the growing number of amateur performers in Vienna, and was arranged near the time for various other trios including two Violins and Bass, two Flutes and Viola, two Clarinets and Bassoon and various Piano settings. The most common format was for two Oboes and Cor Anglais. With this in mind, I decided to arrange this work for Tuba/Euphonium Trio, with the third part optional to be played on either Tuba or Euphonium. The work is performed in four movements; I – Allegro II – Adagio III – Minuet and Trio IV – Finale (Presto)
