This is a two part arrangement of Beethoven's Theme and Variations on a Swiss Air WoO 64 for trumpet in Bb and tuba introducing players to the elements of Classical style and more particularly to Beethoven's compositional approach . The simple theme needs to be clearly articulated and played with a detached but not staccato articulation. The WoO is short for Work without Opus Number and there are many jewels found in this category of work by Beethoven. A tempo of 132 quarter note beats to the minute is recommended for the playing of the theme and variations although variations 2 & 3 need to be played at a slightly slower tempo.
