suite

I'm a little stuck... Click here to teach me more about this clue!

'musical' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for suite that I've seen before include "Extensive accommodation" , "Train of followers" , "Three-piece - -" , "Adjoining rooms" , "Musical composition" .)

I've seen this clue in The Globe and Mail and The Telegraph.
