Tenor tackling new work gets support in studio (7)
I believe the answer is:
monopod
'support in studio' is the definition.
(one-legged tripod in a photographer's studio)
'tenor tackling new work' is the wordplay.
'tenor' becomes 'mood' (tenor can mean something's mood or message).
'tackling' indicates putting letters inside (I've seen this in other clues).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'work' becomes 'op' (abbreviation for opus).
'n'+'op'='nop'
'mood' placed around 'nop' is 'MONOPOD'.
'gets' is the link.
(Other definitions for monopod that I've seen before include "Type of camera support" , "One-legged stand" .)
