descant: [14] Etymologically, descant is a parallel formation to English part song. English acquired it via Old French deschant from medieval Latin discantus ‘refrain’, a compound noun formed from the prefix dis- ‘apart’ and cantus ‘song’. The notion originally underlying it is of a separate vocal line ‘apart’ from the main musical theme. The Middle English form of the word was deschaunt; descant represents a partial 16th-century reversion to Latin discantus.
