B-Flat Clarinet,Instrumental Duet,Trombone - Level 2 - Digital Download SKU: A0.1349244 Composed by Phil Beaman. Advent,Christmas,Early Music,Jazz,Renaissance. 4 pages. Phil Beaman #933989. Published by Phil Beaman (A0.1349244). This jazz composition is based on the hauntingly beautiful 15th century medieval tune that is commonly used for the Advent carol O Come, O Come, Emmanuel. Â I have reharmonized it with the accompaniment in a Key Signature a fifth above that of the melody. Â The accompaniment, part 2, has a broken two chord ostinato throughout written as a walking bass line. Â I have altered the melody, part 1, and moved much of it to the off beats. Â As in period early music, I allow occassional dissonances in order to keep the ostinato. Â This piece makes a wonderfully useful and unique addition to the season's repertoire. Â (I have also published a version on this site with text so it can be sung by a soloist or unison choir with piano accompaniment.) Â (Also as a piano solo.)range - part 1 melody - 10th, middle C to E; part 2 walking bass line, octave and a half, bass clef low A to D above middle C2 pages score, 1 page @ part, Â 2:05 minutes.
