A piano might have 88 keys, but there are over 200 tuning pins in every piano! So it can take a while to adjust them all. A piano may also need to be tuned multiple times in a session to get the best result.

For modern pianos, I recommend allowing 2-3 hours for your first appointment with me.
For older pianos, (especially pianos that are overdampers), I recommend allowing 3-4 hours for your first appointment with me.

If you have known issues with the piano, (such as broken strings) it is good to contact me so that I can allow additional time for your appointment.

(Some older upright pianos, have a damper system called “over dampers”. These pianos require additional time to carefully remove the overdampers, and then require additional time to carefully reinstall the over damper mechanism.)
