## What is CantuStudio?

CantuStudio helps choir directors, music teachers, church musicians, composers, and arrangers turn a melody into a structured SATB choir draft.

Import or enter a melody, choose the musical context, generate a four-part draft, review voice leading, hear playback, and export PDF, MIDI, or MusicXML for rehearsal or further editing.

The app supports English and Brazilian Portuguese, keeps language and region settings separate, and syncs accounts and generated work through the CantuStudio backend.
