Saxophone Tuner
Tune your saxophone online with your microphone. Choose alto, tenor, soprano or baritone and the tuner shows the written note for your sax. On alto sax, the band’s concert B♭ is a written G; on tenor sax it is a written C.

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. Point the microphone toward the bell or the instrument from about an arm’s length. 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 reference note button to hear its note and tune by ear.

How to tune your saxophone
- Warm up for a minute or two.
- Choose your saxophone in the settings, press Start tuner and play a long, steady note.
- If you are sharp, pull the mouthpiece out a little on the neck cork. If you are flat, push it further on.
- Check a few notes across the range and keep your embouchure relaxed.
Alto and tenor sax transposition
The alto and baritone saxophones are in E♭: alto sounds a major sixth lower than written, baritone an octave and a major sixth lower. Tenor and soprano are in B♭: soprano sounds a whole step lower, tenor an octave and a whole step lower. The tuner does the math for you.
