Sound tip for virtuoso pianist (5)
I believe the answer is:
liszt
'for virtuoso pianist' is the definition.
(Franz Liszt, 1811-1886)
'sound tip' is the wordplay.
'sound' indicates a 'sounds like' (homophone) clue.
'tip' becomes 'list' (both can mean to tilt).
'list' is a homophone of 'LISZT'.
(Other definitions for liszt that I've seen before include "Hungarian composer,d. 1886" , "music writer" , "Franz . . . . ., 19th century Hungarian composer and pianist" , "He scored" , "Hungarian piano virtuoso, d. 1886" .)
