Harmonium Lessons
Read full descriptionHide full description
Learn harmonium the way a good teacher would: find your Sa, play a responsive instrument, and practice sargam and alankar lessons that listen to you. LESSONS THAT LISTEN Work through swara foundations and structured alankar patterns, now in all 10 thaats with speed tiers. Hear a phrase, play or sing it, then see pitch feedback on every note. A take with too little clear evidence gets no score instead of a guess. A REAL-FEELING HARMONIUM Play a sampled-reed keyboard with bass, main and treble reeds, coupler, assisted or manual bellows, key sizing, octave navigation, transpose and tuning options. Your Sa follows the keyboard labels and the reference drone. FIND YOUR SA Sing, hum or play one comfortable, steady note. Sa changes only when the microphone hears it clearly; otherwise your current choice stays and you can retry or pick Sa by hand. READ NOTES YOUR WAY Sargam labels in Roman, Devanagari or Gurmukhi, moving with the Sa you chose. A DAILY RIYAZ HABIT A Sa-pitched drone, a quiet practice bed, attempt history, pitch traces, Riyaz Sadhana and guilt-free rest days. No account needed. PRACTICE COACH Get extra practice advice from the optional cloud coach, which uses an AI service. It asks your permission before sending your practice numbers, and your audio never leaves your phone. PRIVACY BY DESIGN The microphone listens only when you ask. Audio and pitch traces stay on your device. SOLOIST HARMONIUM PRO Seven lessons are free. Pay once with Lifetime to unlock every lesson and pattern for good, or choose the monthly or yearly plan, which also raises the practice coach's daily allowance. Plans renew automatically until cancelled in your App Store settings; Lifetime never renews. Restore purchases in Settings.
