Sangeet Parijat

Doṣa Coach

Ahobala's 29 gāyaka-doṣas — the catalogued faults that vocal pedagogy in the Sangeet Parijat tradition treats as worth training out. Sing into the mic and the engine surfaces the ones it sees, family by family.

Sing freely — sustained swaras, mini phrases, or full sancaras.

The engine watches pitch accuracy, vibrato, harshness, breathiness, and nasality in real time, then aggregates phrase-shape doṣas at the end. Tonic anchored at 261.6 Hz from your saved Sa.
