Comma tuner
Listens to a note through the microphone and shows the nearest pitch on the 53-comma Arel-Ezgi-Uzdilek scale and how many commas it is off.
How to read it: the large text is the Western note name and octave (B3); the plus/minus number next to it is the AEÜ accidental in commas (−1 koma flat, +4 bakiye sharp…). The name below is the perde’s name in Turkish music (Segah, Rast, Dügah…). “2 commas sharp / flat” tells how far the note you play is from that perde; 1 comma is about 22.6 cents.
The microphone sound is processed only in your browser and never sent anywhere. Play a single pitch in a quiet place and hold it for a few seconds.
Add it to your home screen as a separate app: opens with one tap and works offline too. Free.
What is the comma tuner?
The comma tuner is an online tuner that measures the frequency of the sound from your microphone and compares it with the nearest perde in the Arel-Ezgi-Uzdilek system, which divides the octave into 53 commas. Western tuners only recognise the 12 semitones; this tuner also shows comma perdes such as Segâh, Eviç and Hüzzam, and tells you how many commas flat or sharp you are. Use it to tune the kanun, oud, bağlama, tanbur, ney or violin, and to practice intonation.
Frequently asked questions
Which instruments does the online tuner work with?
It works with any instrument or voice that produces a single note: kanun, oud, bağlama, tanbur, cümbüş, ney, violin, clarinet and the human voice. While tuning, play one string or one note at a time; if several notes sound together, the reading gets confused.
How is it different from a Western tuner?
Western tuners show the sound against the nearest semitone and treat the comma perdes of Turkish music as "out of tune". This tuner reads the sound in the 53-comma AEÜ system: it shows perdes such as Segâh (Si −1) and Eviç (Fa +4) by name and gives the deviation in commas, not cents.
Can I change the reference A frequency?
Yes. You can change the reference A frequency (440 Hz by default), so you can tune your instrument to the pitch level of your ensemble or of a recording.
Is my microphone audio recorded?
No. The sound is analysed only in your browser, on your device; it is never sent to a server or recorded.
