Cracked notes that come to one's ears (5)
I believe the answer is:
tones
'come to one's ears' is the definition.
I can't judge whether this defines the answer.
'cracked notes' is the wordplay.
'cracked' is an anagram indicator.
'notes' with letters rearranged gives 'TONES'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for tones that I've seen before include "Shades" , "Qualities of colour, music or speech" , "Qualities of people's voices" , "Notes, characters" , "Tints of colour" .)
