Songs one relied on arranging? (6)
I believe the answer is:
lieder
'songs' is the definition.
(lied is a kind of song)
'one relied on arranging?' is the wordplay.
'relied' can be anagrammed to 'LIEDER'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for lieder that I've seen before include "songs from Berlin?" , "[COMPOSITION] s" , "German songs for piano and solo voice" , "German Romantic songs for solo voice" , "Musical settings for solo voice and piano" .)
