Sostenuto: Music Practice

Never forget a song again. Sostenuto schedules exactly what to practice with spaced repetition and an AI coach, so your repertoire compounds daily.

Build a Repertoire You'll Never Forget.

Stop learning songs just to forget them two weeks later. Sostenuto is the first music practice system built on the science of the Forgetting Curve and Spaced Repetition (SRS).

Most musicians spend 80% of their time relearning what they've already studied. Sostenuto flips the script. Our intelligent scheduling system tells you exactly WHAT to practice and WHEN - right before your brain is about to forget it.

Meet Maestro AI, your personal practice coach. Maestro analyzes your study logs and gives you targeted advice based on your real data - not generic tips.

THE SOSTENUTO METHOD:

1. ADD: Catalog the songs, scales, or phrases you want to master.
2. PRACTICE: Use the built-in session tracker and capture audio/video for self-critique.
3. RETAIN: Our SRS algorithm schedules your reviews so your progress compounds daily.
