Outil web léger, entièrement dans le navigateur, pour la lecture à vue et le solfège. Inspiré de la manus guidonica de Guido d'Arezzo et de la pédagogie musicale historique, Guidonica fait défiler sans fin une notation musicale générée de façon procédurale sous une tête de lecture fixe, en synchronisation avec un métronome synthétisé par Web Audio.

How Guidonica is made
Guidonica is designed, tested and maintained by A. C. Lo Cascio, who writes much of its code with an AI coding assistant (Anthropic's Claude) and reviews every change. No AI runs inside the app: exercises come from a random generator whose rules are documented in the source, and the metronome is synthesized live in your browser.
Support Guidonica
Guidonica is free, with no ads and no tracking. If it helps your practice, a voluntary tip funds its development. Tips unlock nothing: it's simply a thank-you.
