Time for some music (5)
I believe the answer is:
tempo
'time' is the definition.
(tempo is a kind of time)
'for some music' is the wordplay.
'for' becomes 'temp' (I am not sure about this - if you are sure you should believe this answer much more).
'some' means to look at the middle letters.
'music' becomes 'soh' (a note in the do-re-mi system).
The middle letter of 'soh' is 'o'.
'temp'+'o'='TEMPO'
Can you help me to learn more?
(Other definitions for tempo that I've seen before include "Pace of a musical piece" , "Speed of 3A" , "Musical beat or rhythm" , "(Musically) the speed to be played" , "Speed at which a musical composition is to be played" .)
