The first composer to journey (6)
I believe the answer is:
travel
'journey' is the definition.
(synonyms)
'the first composer' is the wordplay.
'the first' becomes 't' (1st letter of 'the').
'composer' becomes 'ravel' (Maurice Ravel).
't'+'ravel'='TRAVEL'
'to' is the link.
(Other definitions for travel that I've seen before include "Go on a trip" , "Varlet (anag.)" , "Journey from one place to another" , "tour" , "Move from one place to another" .)
