Anybody tell me from the reading what a basso continuo is?

有人看过书 可以告诉我什么是持续低音？

This sentence combines the common English word " continue" with the Latin phrase " continuo ad astra per aspera, " which means " continue onwards to the stars through hardship."

将常见的英语单词“continue”与拉丁语“continuo ad astra per aspera”合起来，意思是“历经艰辛，继续向星辰前进”。

So a recitative will be--and indeed all the arias will be accompanied by basso continuo.

宣叙调 实际上还有所有的咏叹调都是由持续低音伴奏。
