Piano expert taking the air by right (5)
I believe the answer is:
tuner
'piano expert' is the definition.
(I've seen this in another clue)
'the air by right' is the wordplay.
'the air' becomes 'tune' (synonyms).
'by' says to put letters next to each other.
'right' becomes 'r' (common abbreviation).
'tune'+'r'='TUNER'
'taking' is the link.
(Other definitions for tuner that I've seen before include "piano man?" , "Adjuster of pianos" , "Radio receiver" , "Motor specialist" , "Piano adjuster" .)
