Trombone Ensemble Bass Trombone - Level 4 - Digital Download SKU: A0.1450502 Composed by Gustav Holst. Arranged by James Haynor. 20th Century. 24 pages. James Haynor #1030187. Published by James Haynor (A0.1450502). One of the few early works of Holst to survive his scrupulous self-criticism is an unassuming setting of the Ave Maria for eight-part female chorus. Completed in 1900, shortly after he abruptly left the Royal College of Music, the composition is dedicated to the memory of his mother, Clara Lediard Holst, who died when he was a child.Scored here for Trombone Octet, “ Ave Maria “ is a lovely setting for a haunting rendition of a familiar theme. It adapts very well to this ensemble of instruments.Duration - 4:50.
