Amusing daughter with sound of drum (5)
I believe the answer is:
droll
'amusing' is the definition.
(I've seen this before)
'daughter with sound of drum' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'with' means one lot of letters go next to another.
'sound of drum' becomes 'roll' (drum roll).
'd'+'roll'='DROLL'
(Other definitions for droll that I've seen before include "Drily witty" , "Quaintly amusing" , "Comical in an odd or whimsical manner" , "Strangely amusing" , "rum" .)
