KK: /ˈθɜroʊˌbæs/
A musical term referring to a bass part that is accompanied by harmonies, typically played on a keyboard instrument, used in Baroque music.
The composer wrote a thoroughbass for the ensemble to follow during the performance.
Thoroughbass → It is formed from "thorough" (from Old English *þurh*, meaning through) and "bass" (from Italian *basso*, meaning low). The term refers to a musical practice that involves a continuous bass line played throughout a piece, hence the idea of going 'through' the bass line.
Think of going 'through' ('thorough') a 'low' ('bass') musical line, which helps you remember that thoroughbass refers to a continuous bass in music.
