I'm a Geelong based piano tuner with a Diploma of Piano Technology from the U.S. Randy Potter School of Piano Technology. I have a Bachelor of App. Science degree and for the last 30 years I've worked as a professional pianist and piano teacher.
piano tuning - your piano ideally needs to be tuned annually to A440 Hz (also known as concert pitch) .
pitch raising - old pianos can be a semitone or more flat.
action regulation - optimising how the piano feels to play by action adjustments.
on the job repairs - string replacement, missing keytops, sticking notes, broken hammers, ringing dampers, sustain pedal adjustment etc.
piano cleaning - inside of grand pianos, vacuuming inside uprights and under the piano keys, compressed air cleaning of grand and upright actions.
workshop repairs - action rebuilding (action felt, springs, dampers, repinning hammers etc), full keytop replacement.
