Transmit sounds, barely captured in repetitive song (9)
I believe the answer is:
roundelay
'repetitive song' is the definition.
'roundelay' can be an answer for 'song' (roundelay is a kind of song). I'm not sure about the 'repetitive' bit.
'transmit sounds barely captured' is the wordplay.
'transmit' becomes 'relay' (I've seen this before).
'barely' indicates the central letters (the word is bare of its external letters).
'captured' indicates putting letters inside.
The middle of 'sounds' is 'ound'.
'relay' going around 'ound' is 'ROUNDELAY'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for roundelay that I've seen before include "Slow dance - song with refrain" , "Slow, circling medieval dance" , "Short, simple song" , "Slow, medieval dance, in a circle" , "Circle dance; simple song" .)
