Frequently asked questions
What is standard banjo tuning?
Open G: g4 D3 G3 B3 D4, starting with the short 5th string. Strumming all open strings plays a G major chord.
Is my audio recorded or uploaded?
No. The tuner analyses the sound from your microphone in your browser, a few times a second, and throws it away. Nothing is recorded, saved or sent to a server.
Why does the tuner jump between notes?
Usually because more than one string is ringing, the room is noisy, or the note has faded. Mute the other strings with your fretting hand, pluck firmly, and read the needle while the note is still strong. Moving closer to the microphone helps on laptops.
