Choral piece uplifted in tribute to monarch (5)
I believe the answer is:
motet
'choral piece' is the definition.
(I've seen this before)
'uplifted in tribute to monarch' is the wordplay.
'uplifted' says the letters should be written in reverse.
'in' indicates a hidden word.
'tetom' can be found hidden inside 'tribute to monarch'.
'tetom' backwards is 'MOTET'.
(Other definitions for motet that I've seen before include "work by Tallis, for example" , "Word; fixed period" , "Totem (anag) ? anthem" , "Polyphonic choral liturgical piece" , "Short sacred choral piece" .)
