Made for the music you play
Western tuners snap to 12 notes. Persian music lives between them. CHAKAM works in 24 steps per octave, with koron and sori built in.
Microtonal tuner
Tune to the 24-step Iranian scale, or pick a dastgāh such as Shur, Segah, Chahargah or Mahur and a tonic to get its exact intonation.
Recording to sheet music
Record or upload a performance and get notation with Persian accidentals (koron and sori) that you can edit and export as MusicXML.
Your library
Keep your transcriptions in one place, rename and refine them, and open them on any device where you sign in.
Community
