Sonata Pian' e Forte, from Sacrae Symphoniae (1597), Ch.175 (McKinney)
Baroque. Gabrieli's Sonata Pian 'e Forte for 8-part antiphonal trombone ensemble has been arranged (down a fifth from the original key) by Russel McKinney. The work (Ch.175) is part of the 1597 Sacrae symphoniae, published posthumously which contains sixty-three choral and instrumental works, many in multi-choir formations. This 8-part Sonata is in two choirs....a high one and a low one (in this case choir II uses one tenor & three bass trombones with an optional contrabass trombone).
The most unique aspect of this masterpiece is its use of printed dynamics...originally thought to be the first work of its sort; Pian (soft) and Forte (loud). These dynamic markings are central to the structure of the work.
