Tuner not hearing you?
- Allow the microphone. If you blocked it: in Chrome or Edge, click the icon left of the address bar → Microphone → Allow, then reload. In Safari on iPhone, tap aA → Website Settings → Microphone → Allow. In Firefox, click the crossed-out microphone in the address bar. On a Mac, also check System Settings → Privacy & Security → Microphone for your browser.
- Open the page in Safari or Chrome. In-app browsers (Instagram, Facebook, TikTok) often block the microphone.
- Play one note at a time, louder. Hold your phone or laptop close to the instrument and let the string ring. A quiet room helps.
- Wrong octave or jumping notes? Let the attack fade for a moment — the reading settles once the note is steady.
- No microphone at all? Tap a string button to hear its note and tune by ear.

About Drop A tuning
Drop A is one of the lowest common guitar tunings and is used in modern metal and djent. The three lowest strings make an A power chord when played open.
On a normal 6-string guitar the strings go very slack this low. Most players use a baritone guitar or a very heavy string set. On a 7-string guitar, drop A means A E A D G B E: only the 7th string drops from B to A.
How to tune to Drop A
- Press Start tuner above and allow the microphone. The tuner is already set to Drop A.
- Play one string at a time. The tuner shows which string it hears and whether to tune up or down.
- Turn the peg until the needle is centered and the note turns green. Tap a string button to hear its target note.
- After all strings are done, check them again — changing tension on one string pulls the others slightly.
