Guitar Tuner
Allow the microphone, then play one open string. The needle turns green when you’re within 3 cents of the note.
SettingsGuitar · Standard · A = 440
The reference note holds until you tap the string again.
The needle glides to each reading.
A is the pitch of A above middle C. Leave it at 440 unless you're tuning to a recording or a band that isn't.
Your microphones are listed by name once you've allowed the microphone.
To tune by ear, tap a string to hear its note; tap it again to stop.
Play one string at a time, and stop the last one before you play the next: a string still ringing can drown out the new one.
Tips
Tune up to each note, not down to it: if a string is sharp, go below the note and come back up. The string holds its pitch better that way.
Play near the microphone, and let the string ring. The first moment after you pick it reads a little sharp; watch where the needle settles.
The sound never leaves your device. The tuner listens only while it says so, and stops when you tap Stop listening or leave the page.
