Choral piece swamped by remote tom-toms, on recall (5)

I believe the answer is:
motet
'choral piece' is the definition.
(I've seen this in another clue)
'swamped by remote tom-toms on recall' is the wordplay.
'MOTET' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for motet that I've seen before include "Anthem or church cantata" , "Piece for choir" , "Word; fixed period" , "Piece of sacred music" , "10 [COMPOSITION]" .)
