Soloist Harmonium

Build a steadier harmonium practice around your own Sa. FIND YOUR SA Sing, hum, or play one comfortable, steady note. The confidence-gated setup changes Sa only when microphone evidence is clear. If the evidence is unclear, Soloist Harmonium keeps your current choice and invites you to retry or choose Sa manually. PLAY A RESPONSIVE INSTRUMENT Practice on a sampled-reed keyboard with bass, main, and treble controls, coupler, assisted or manual bellows, key sizing, octave navigation, transpose, and tuning options. Your saved Sa follows the keyboard labels and reference drone. LEARN WITH HONEST FEEDBACK Work through swara foundations and structured alankar patterns. Hear a phrase, try it, then review pitch feedback. A take with too little reliable evidence receives no score instead of a guess. READ NOTES YOUR WAY Switch relative sargam labels between Roman, Devanagari, and Gurmukhi. The labels move with the Sa you selected. BUILD A PRACTICE HABIT Use the Sa-pitched drone, a quiet practice bed, local attempt history, pitch traces, Riyaz Sadhana, guilt-free Vishram rest days, and on-device practice guidance. No account is required for setup or foundation practice. PRIVACY BY DESIGN Microphone listening starts only when you ask for it. Audio and pitch traces stay on your device and are not uploaded. Optional cloud refinement is off until you enable it and sends bounded practice aggregates, never audio. Soloist Harmonium offers optional monthly and yearly auto-renewing subscriptions plus a Lifetime Family purchase. Exact localized purchase details, renewal terms, Family Sharing availability and eligibility appear in the App Store before purchase. Restore purchases in Settings.
