Shout out to the Sound of music.
Blup
"To the sound of" could pass as an indicator for a homophone.Would that misspelling get into a normal crossword?
There might be a clue in there somewhere, something like: Sounds like auxiliary percussion instrument with quality of the music by little Irene. (10)Were it a homophone, yes, but one is pronounced tim berr and t'other tam brr.
