Get support acquiring piano for musician (8)
I believe the answer is:
bagpiper
'for musician' is the definition.
(bagpiper is a kind of musician)
'get support acquiring piano' is the wordplay.
'get' becomes 'bag' (bag can mean to secure or obtain).
'support acquiring piano' becomes 'piper' (I am not sure about this - if you are sure you should believe this answer much more).
'bag'+'piper'='BAGPIPER'
Can you help me to learn more?
(Other definitions for bagpiper that I've seen before include "(Scottish) musician" , "Pibroch player" , "Player of traditional Scottish musical instrument" , "Wind musician" , "Scots musician" .)
