Rhythm of speech (7)
I believe the answer is:
cadence
'rhythm of speech' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cadence that I've seen before include "Closing bars" , "Inflection; voice pitch fall" , "Rhythm or beat" , "Close of a musical phrase" , "that may be perfect for musicians" .)
