'a little craft' is the definition.
The definition suggests a singular noun which matches the answer.

'roughly shown by french composer' is the wordplay.
'roughly' becomes 'ca' (abbreviation for circa).
'shown by' means one lot of letters go next to another.
'french composer' becomes 'Ravel' (Maurice Ravel).
'ca'+'ravel'='CARAVEL'
