Play a Strauss piece with spirit (5)
I believe the answer is:
strum
'play' is the definition.
(I've seen this before)
'a strauss piece with spirit' is the wordplay.
'a strauss piece' becomes 'st' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'spirit' becomes 'rum' (alcoholic spirit).
'st'+'rum'='STRUM'
Can you help me to learn more?
(Other definitions for strum that I've seen before include "'Sound the strings, musically (5)'" , "Play stringed instrument with sweep of hand" , "Play badly on a guitar" , "Plays guitar" , "Play a banjo" .)
