Calibrating, a musical instrument perhaps (6)

I believe the answer is:

tuning

(Other definitions for tuning that I've seen before include "Calibrating a musical instrument" , "- Fork aids a musician" , "Modifying vehicle engines to improve their performance." , "Correcting musical pitch" , "Adjustment (which can be fine)" .)

I've seen this clue in The Irish Times.
