1620—Italy

Ercole Porta’s Corda Deo dabimus, contained in the collection Sacro convito, is scored for soprano voice, alto voice, and 3 trombones. Historian Jerome Roche later coins the phrase “trombone motet” for this type of piece, a genre that culminates in Schütz’s Absalom fili mi (1629) (Roche, North Italian 82). Also from the same collection is Porta’s Messe secunda toni, which calls for 2 violins and 3 trombones to accompany a 5-part choir; when doublings occur, trombones double the 3 lowest voices (Schnoebelen, The Role of the Violin).
