Time To Testify is a tuneful gospel/rock chart that is sure to find its way into the big band folders of developing jazz bands. Opening with a short, notated alto solo, this easy level chart kicks into a strong groove that will energize your next concert program. The piece is playable by as few as 9 pieces and is expandable to 17. The lead trumpet extends only to A5. One line extends to C#, but can played an octave below as indicated on the part. The trombone range goes to G4. The solo section has very accessible chord changes, and as with most of Jarvis' offerings, frequent articulations are provided for the horns. The rhythm parts are an integral part of the arrangement, not merely an afterthought. This piece is guaranteed to get your audience clapping along with the band! Playable with optional reduced or expanded instrumentations.
