Song or melody to perform without piano (3)
I believe the answer is:
lay
'song' is the definition.
(lay is a kind of song)
'perform without piano' is the wordplay.
'perform' becomes 'play' (playing is a kind of performing).
'without' suggests deleting specific letters.
'piano' becomes 'p'.
'play' with 'p' taken out is 'LAY'.
'or melody to' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for lay that I've seen before include "Air" , "Place (bet)" , "Arrange" , "Impose (a burden)" , "Set down; song" .)
