How does the virtual harmonium work?

Our online harmonium uses dual-reed bank physical modeling with animated air bellows and Indian classical Sa-Re-Ga-Ma note badges.

Click or use your keyboard to play.

What are Swardas (Sa, Re, Ga, Ma) on the harmonium?

Swardas are the 7 primary notes of Indian classical music: Sa (Shadj), Re (Rishabh), Ga (Gandhar), Ma (Madhyam), Pa (Pancham), Dha (Dhaivat), and Ni (Nishad).

What is the Octave Coupler feature?

The octave coupler mechanically or electronically engages the reed an octave higher, doubling the note for a richer, fuller harmonium sound.

How do I practice Riyaz (vocal practice) with this tool?

Play individual notes to match pitch with your voice, drill scale patterns (Thaats/Ragas), and use the octave coupler for acoustic depth.

What keyboard keys play harmonium notes?

Keys A through K play chromatic notes, while W-E-T-Y-U cover Komal and Teevra Swardas.
