## What is Sonachord?

Sonachord is a piano learning app with a chord-focused approach.

Follow a guided path of 28 chapters — from your first notes and triads to extended chords, progressions, and ear training. You'll learn how chords look, sound, and work in real music.

In the app you can:

- Learn piano chords step by step
- Practice recognition, recall, and progressions
- Train your ear with focused exercises
- Play along with the on-screen keyboard, MIDI, or a real piano
- Use local acoustic detection through your microphone
- Practice offline, with no account required

Sonachord is a great fit for beginners, returning players, students, and teachers.

Privacy:
No account required. Your progress stays on your device. The microphone is used only for local note detection — audio is never recorded, stored, or uploaded.

Payment:
No subscription. Full access to all chapters and exercises unlocks with a one-time in-app purchase.
