Range in "The Sound of Music" (4)
I believe the answer is:
alps
'range in the sound of music' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for alps that I've seen before include "Slap about in mountains" , "Swiss mountains" , "Slap (anag.)" , "Mountain system, highest peak Mont Blanc" , "European mountain range" .)
