There's many a dance in his music (6)
I believe the answer is:
chopin
'there's many a dance in his music' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition. I also know that 'music' relates to this answer.
'there's many a dance in' is the wordplay.
'there's' means one lot of letters go next to another.
'many' becomes 'c' (C is the Roman numeral for 100).
'a dance' becomes 'hop' (hop is a kind of dance).
'c'+'hop' is 'chop'.
'chop'+'in'='CHOPIN'
Can you help me to learn more?
