'improvised music' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'heading north in piazza jeer flautist's' is the wordplay.
'heading north' says the letters should be written in reverse (in a down clue, letters travel north).
'in' indicates a hidden word.
