🎹 HARMONIUM
Play a 36-key keyboard spanning 3 octaves with authentic sound. Select from 100+ raags and practice interactively — auto-play aaroh, avroh, pakad, and alaap with note-by-note visual guidance. Enable raag-guided key highlighting and play smooth meend glides between notes.

🎵 RAAG PRACTICE
Explore 100+ raags with complete definitions: aaroh (ascending scale), avroh (descending scale), pakad (signature phrase), and alaap (exposition). Follow along with Bhatkhande swar notation and a synchronized Tanpura drone.

📷 AI NOTATION SCANNING
Point your camera at any Bhatkhande notation sheet and let AI extract the notes automatically. Recognizes Devanagari swar notation, komal/teevra accents, octave markers, sustain marks, and lyrics — all taal-aware for beat-aligned output.

🎼 SONG COMPOSITION
Build multi-section songs with independent instrument control per section. Choose Tabla, Tanpura, Sur Peti, Swar Mandal, or Manjira for each section. Add custom audio tracks, Bhatkhande notation, and lyrics. Share your compositions with the SurSadhak community.
