TuneHow to tune a alto sax
- Press Start Tuning and allow microphone access when your browser asks.
- Play one note. Play one long, steady note, close to the microphone, and let it ring.
- Read the display. The big letter is the nearest note. The bar shows how far off you are: left is flat (tune up), right is sharp (tune down).
- Turn until it goes green. Inside your tolerance (±3 cents by default) the display turns green and the string gets a check mark.
Tips
- Tune on written F♯ or A and move the mouthpiece on the cork.
- Push the mouthpiece in to go sharper, pull it out to go flatter.
- Check octave notes; a low written D sharp of pitch often means the mouthpiece is too far in.
FAQ
Does this alto sax tuner show written or concert pitch?
It shows the written note for a E♭ alto sax by default, so it matches the music you read. Choose “Concert pitch (C)” under Settings to see sounding pitch.
Why am I sharp at the start and flat later?
Instruments warm up as you play. Tune after a few minutes of playing, and check again during long rehearsals.
Can I tune to A = 442 Hz?
Yes. Open Settings and set Reference A4 to 442, or any value from 400 to 480 Hz.
