Answer:
Maybe, I do. I don't think.. I listen to his song.. :(

Answer: rectative, aria, ground bass and triple.
Explanation:
The rhythm of the RECITATIVE is free, and the rhythm of the ARIA is more regular. The harmony of the aria is based on a chromatic GROUND BASS that descends by half step. The slow and melancholy TRIPLE meter expresses in the aria Dido's lamentation at Aeneas's departure.
Piano sonatas were very helpful in the classical genre that was the most important to composers of the classical era.
