How to use the chromatic tuner
Press Start tuning and play or sing a steady note. The large letter is the closest note. The needle and the number below it show how many cents you are away from it. Within ±5 cents the needle turns green.
Transposing instruments
Many wind and brass instruments are transposing, which means the note on the page is not the note that sounds. Choose your instrument’s key in the menu and the tuner shows the note you read.
B♭: trumpet, cornet, clarinet, tenor and soprano saxophone. Written notes sound a whole step lower.
E♭: alto and baritone saxophone. Written notes sound a major sixth lower.
F: French horn. Written notes sound a perfect fifth lower.
It recognises all 12 notes in every octave, so you don’t need a preset. It tunes anything: wind and brass instruments, voice, piano or an unusual string tuning.
How to use it
Choose your instrument’s key in the menu, press Start tuning and play a steady note. Adjust until the needle is centred and the display turns green.
Frequently asked questions
What is a chromatic tuner?
A chromatic tuner can find any of the 12 notes in every octave, so it works for any instrument and any tuning, not just guitar strings.
What does the B♭ / E♭ / F setting do?
On transposing instruments, the note you read is not the note that sounds. With B♭ selected, a concert B♭ is shown as C, which is what a trumpet or clarinet player reads.
Can I use it as a voice tuner?
Yes. Sing a steady note and the tuner shows the closest note and how many cents you are off. It’s great for practising matching a note. There is also a separate voice tuner page.
How accurate is it?
In a quiet room with a clear tone, readings stay within about ±1 cent. Background noise and very low notes make it less accurate.
