Jazzman Hines (4)
I believe the answer is:
earl
'jazzman hines' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for earl that I've seen before include "British nobleman" , "British peer and Dublin street" , "A lord like Lear" , "Male equivalent of a countess" , "Rank immediately above viscount" .)
