What is a 17th-century solo vocal piece of music called?

False

It could be an aria, a cantata, a song.

Searching on the word suite doesn't bring up anything vocal. In the 17th century a suite was a set of interrelated pieces for a solo instrument or an orchestra. Bach wrote suites for cello, for violin, for keyboard and for orchestra. A suite could also be a selection of pieces from a larger work, like Handel's Water Music Suite, made of pieces from a large set he wrote to be played as his King's barge floated down the Thames, or his Suite from the Music For The Royal Fireworks.
