Enthusiasm about ace tuba player's sound? (6)
I believe the answer is:
oompah
'sound?' is the definition.
(I have seen 'brassy sound' mean 'oompah' so perhaps 'sound' could also mean 'oompah')
'enthusiasm about ace tuba player's' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is present in the answer.
'enthusiasm' could be 'oomph' (I've seen this in another clue) and 'oomph' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oompah that I've seen before include "A Sound of Music" , "Sound of deep brass instrument (colloq.)" , "brassy sound" , "Noise of brass (colloq.)" , "Tuba sound" .)
