Don’t You Worry ‘Bout A Thing (Stevie Wonder) inspired by Tori Kelly from “Sing” custom arranged for vocal solo and SAT(B) back vocals, full five piece rhythm parts (keys, bass, guitar, drums and percussion) and a four piece horn section: trumpet 1, trumpet 2 (or alto sax), trombone (or tenor sax), and baritone sax (or trombone sub) in the key of F. One step below the original key. Ask about other keys. This is considered a pro arrangement and parts are fairly difficult. Be sure to check out the midi audio track of this chart and the sample score of pages from this arrangement.
Note that there is a full 5444 piece big band arrangement version of this song in both keys of G and F.
