Prevaricated over limits of Elgar’s vocal works (6)
I believe the answer is:
lieder
'vocal works' is the definition.
(I've seen this before)
'prevaricated over limits of elgar's' is the wordplay.
'prevaricated' becomes 'lied' (I've seen this in another clue).
'over' says to put letters next to each other.
'limits of' means to remove the middle letters.
'elgar' with its middle taken out is 'er'.
'lied'+'er'='LIEDER'
(Other definitions for lieder that I've seen before include "songs by Schumann?" , "Musical settings for solo voice and piano" , "German songs for piano and solo voice" , "Art songs for voice and piano" , "German Romantic songs for solo voice" .)
