Accounts, access and navigation
The header contains Home, Jam, Laboratories, Composition and Learning. Options groups licence, account, manuals, tutorials and language; administration is shown only to administrators. Theme and Back remain directly accessible. On narrow screens, open ☰ for navigation. Presentation pages and manuals are public; using the musical tools requires registration and sign-in.
- Open IntervalsMaster and sign in. If you are registering, complete email verification.
- Select IT/EN and the light or dark theme using the general controls.
- After signing in, choose Laboratories, Composition or Learning. Learning separates Guided courses from Online lessons, including Live Classroom, Lesson Player and Premium Lessons, according to your account access.
- If navigation is grouped under a compact menu button, open it to see all destinations.
| Area | Purpose |
|---|---|
| Laboratories | Free practice, chords and phrase collections for guitar, piano, bass and drums. |
| Composition | Repertoire, harmony laboratories, grooves and the multitrack DAW. |
| Learning | Guided courses and online lessons, according to your purchases, licence and account permissions. Additional courses are also available. |
| Jam | Jamulus or JackTrip rooms for playing together, viewing connections and managing multitrack recordings. |
| Live Classroom | Live teaching sessions led by a teacher using the tools their account supports. |
Pro enables the musical features included in the plan; EDU adds teacher tools and Live Classroom. Guided courses and Premium content may require a separate purchase. Check the Licence panel and the access information shown by each feature.
After signing in, the instrument button in the header opens Study settings. Instrument selection is global: it is shared across functions and languages. Menus and classroom destinations show only compatible functions. An incompatible function does not erase your saved instrument. Instrument and parameter changes in the popup apply only with Confirm; restoring preferences does not start audio. In Administration → Compatible instruments, choose Section and Function to manage availability.
Personal API and Swagger documentation
The /account/api page, available after sign-in, manages personal tokens; it is no longer a header command. Generate a Bearer token associated with your account, shown once and revocable. Swagger documentation is at /api/docs. Send the token in the Authorization: Bearer <token> header. The API retains your licence permissions and limits; keep the token as securely as a password.
