Pitch & tuningTune a guitar with a chromatic tuner
Open-string pitches, why chromatic beats a six-string-only tuner, and how to check fretted notes. Same needle as the band room.
Why not a six-string-only tuner
A lot of guitar tuners only care about open EADGBE. That is fine until you play a fretted note, drop the sixth string, or share a classroom link with a trumpet player.
A chromatic tuner hears all twelve notes. Use it for guitar when you want, and the same page still works for band, orchestra, and voice.
Open strings, then fretted checks
Open the tuner, allow the microphone, and play one string at a time in a quiet room. Aim near 0¢. Standard open strings, low to high: E2, A2, D3, G3, B3, E4.
- Hold the phone near the sound hole or pickups
- Pluck cleanly and let the needle settle — don’t chase every wobble
- Tune low E first, then work up the neck
- Check a fretted note if intonation or action is off
Same tool as the band room
practice cents is built for band rooms first. Guitar works because the tuner is instrument-agnostic, not because this is a guitar-only product. Start at /tuner.
Record, journal, band transposition, and HYKOM are on the iPhone app when you want them. The tuner stays free.
