Published by Bob Marshall (A0.827163). For a moment of peaceful reflection during the Christmas season, the pensive I Wonder As I Wander is a great choice. This arrangement for Bb Trumpet with piano accompaniment perfectly captures the wistful mood of wondering and wandering out under the sky. The introspective, haunting melody is quietly stated throughout the piece with a subtle touch of embellishment and jazz-influenced chording. Key of Gm with a modulation to Am (Trumpet Am - Bm).
