Jeff Reynolds has done a gorgeous job arranging Three Early Sacred Pieces for 4-part Trombone Ensemble:

I. The Passion Chorale, O Sacred Head Now Wounded - Hassler/Graun

II. Cum esset desponsata - Isaac

III. Tu solus qui facis mirabilis - Des Prez

The Passion Chorale is performed during Holy Week. Cum esset is performed during the Christmas season and Tu solus is a Sacred Motet from 1503.

The top part is available in tenor and alto clef parts and all parts are of moderate difficulty in this 7-minute work.
