For listeners, Francesco the poet's beloved, moving line (5)
I believe the answer is:
aural
'for listeners' is the definition.
(relating to ears or 'listeners')
I don't understand how the rest of the clue works.
(Other definitions for aural that I've seen before include "To do with hearing or the ears" , "Hearing-related" , "musical perception" , "of the listener" , "of air" .)
