Piano,Trombone - Level 3 - Digital Download SKU: A0.997639 By Aaron M Booth. By Aaron M Booth. Arranged by Aaron M Booth. Contemporary,New Age. Score and part. 6 pages. Aaron Booth #603288. Published by Aaron Booth (A0.997639). This trombone with piano accompaniment piece was written as a college assignment. The alternation of the duple meter and triple meter patters in the trombone part contract at times with what the piano accompaniment is playing underneath. There is also a different feel when the trombone part changes to the longer flowing melody in the middle before changing back to the original melody, now in a different key to give it even more of a stark contrast.
