Bit of music, repeated element of Strauss, obviously (6)
I believe the answer is:
snatch
'bit' is the definition.
(I know that bit can be written as snatch)
'element of strauss obviously' is the wordplay.
'element of' suggests taking the first letters.
'obviously' becomes 'natch' (I've seen this before).
The first letter of 'strauss' is 's'.
's'+'natch'='SNATCH'
'of music repeated' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for snatch that I've seen before include "Seize abruptly" , "Bit of a song" , "Filch" , "Weightlifting lift" , "Grasp hurriedly" .)
