Ditty (4)

I think it could be either:

tune

song

'ditty' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for tune that I've seen before include "temper" , "'He who pays the piper calls the ...'" , "Optimise the condition of" , "Song" , "Adjust a radio receiver to a frequency" .)

I've seen this clue in The New York Times, the Sydney Morning Herald, The Telegraph, The Mirror, The Star Tribune, The Sun, the Penny Press, The Guardian and the King Feature Syndicate.
