mic off
♭ −50+50 ♯

Turn on the mic to start.

Pluck, don't strum
One string at a time, a firm pick near the soundhole, then let it ring while you turn the peg.
Come up to pitch
If you’re flat, tune up into the note. If you’re sharp, go below and come back up. Strings hold better that way.
Within five cents is in tune
The string turns abalone. Chasing zero on an acoustic is a hobby, not a requirement.
Hear the target
Tap a peg to hear the reference pitch played on a string, not a beep.
