How To Tune A Piano

Step-by-step how to tune a piano.

Just to clarify, I’ve received many questions about how C#3 is used when tuning F4. You’re just using it as a base line. So, whether you’re using the C#3, D3, D#3, E3 you’re not using them to tune F4, F#4, G4, E4. You’re tuning the 4th octave notes off of F3, F#3, G3, G#3. So tune F4 to F3 as close to no beats as possible. Then play C#3 with F3 and listen to how fast the beats are, THIS is your baseline. The beats could be fast, they could be slow, doesn’t matter. Now play C#3 with F4 and listen to the beats. If they sound the same as they did with C#3 and F3 then it’s a perfect 4:2 octave. If when you play C#3 and F4 the beats are faster, then F4 is too sharp compared to F3. If the beats are slower then F4 is too flat. Do the same with the other notes while moving up. This just gets you to the double octave which is what a 4:2 is. So once you get to F5, use F3 as your double octave test which you can now use since you know F3 is already in perfect tune.
