Mozart composed a total of seventeen Church Sonatas. These short single movement works were intended originally for liturgical use as interludes between the epistle and the Gospel. While the early Sonatas were scored for 2 Violins and Organ, the later ones required a full Orchestra.
The Four Church Sonatas No. 2 (K68), No.1 (K67), No. 10 (K244) and No. 17 (K336) by WA Mozart are arranged here for Bb Clarinet by Yona Ettlinger
