Sixteen harmonics to explore.
The alphorn (Swiss alphorn) sounds a series of natural harmonics. These notes give your instrument its very own colour. Some are close to the notes of a piano, others have a character of their own.
AlphornTuner takes this natural series as its reference. You can explore each harmonic and look for a steady sound, while staying tuned in to your horn.
- Five notes just like the piano
- H11 · the Alphorn F
- H7 and H13 · a colour of their own

Play a note. Watch it light up.
The horn-needle follows the note you play. Here, at +3 cents, you are inside the zone you chose. The counter keeps going while you hold the sound.
“Nicely centred, keep going!
Keep that steady breath.”

Your companions in music.
01 / TUNERTuner
Listen to the sixteen harmonics on the wheel. A long press holds the note, so you have time to find it again.
02 / METRONOMEMetronome
Find your tempo, from 30 to 240 beats per minute. Choose from seven time signatures and four subdivisions. Let the swinging horn or the lit-up beats guide you.
03 / PITCH TUNERPitch tuner
Spot the harmonic you are playing and how far off it is. Choose a hold time to practise a steady breath.
04 / SETTINGSSettings
Choose the key of your horn, the reference A and your in-tune zone. You can also adjust the microphone sensitivity to your surroundings.
A setting that follows your horn.
Every horn has its own character. How it was made and how warm it is both shape the pitch of the sound. Take a moment to find your bearings before you play.
Play harmonics 4 to 8, four seconds each. The app uses the middle value of those readings to suggest a reference that suits your horn. You then choose whether to apply it or keep your own setting.

The music carries on as a family.

A few answers before you play
Do I need to install anything?
Just open AlphornTuner in your browser, on a computer, tablet or phone. It is free and there is no account.
What is the difference between the Tuner and the Pitch tuner?
The Tuner plays a reference note for you. The Pitch tuner listens to the one you play and helps you see how in tune it is.
Is this a chromatic tuner?
AlphornTuner is made for the sixteen harmonics of the alphorn. For a piano or a guitar, choose a tuner made for that instrument.
Do I need an internet connection?
Yes, to open the app. The secure site alphorntuner.ch also lets you use the microphone, with your permission.
Now it’s your turn to sound the first note.
Open the app, allow the microphone and play calmly. Your harmonic appears on the screen.
