I believe the answer is:
motet
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">choral composition</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for motet that I've seen before include "Piece for choir" , "Something to sing" , "Church choral composition" , "Church composition - totem (anag)" , "Religious choral composition" .)
