Rate letters from cute MP only just five out of ten (5)
I believe the answer is:
tempo
'rate' is the definition.
(musical rhythm or rate)
'cute mp only just five out of ten' is the wordplay.
'TEMPO' is hidden within the letters.
However, I am not sure how the hidden word is indicated.
'letters from' acts as a link.
Can you help me to learn more?
(Other definitions for tempo that I've seen before include "Rhythm of piece of music" , "Cadence" , "Musical beat or rhythm" , "Pace of a musical piece" , "(Musically) the speed to be played" .)
