About the Project

Absolute Pitch Class is a gamified music education platform, created to make learning music accessible and fun for everyone.

We build with artificial intelligence: it lets us experiment fast and create features with a level of detail and feedback you won't find in most tools.

We started with rhythm training — the foundation of all music — and today we also have sight-reading, ear training (intervals and chords) and reading real music, including files you load yourself in MIDI. Every game with levels and a free mode, a ranking tied to your account, and groups for schools and classes.

For schools and teachers

A whole class practicing at home what they saw in the lesson, and the organizer seeing where each student gets stuck.

  1. Each student creates an account It takes a minute, and you can sign in with Google.
  2. The school requests a group It gets an invite link; whoever joins through it already shows up in the class ranking.
  3. The class ranking Shows each student's level in the four ranked games: Rhythm, Reading, Intervals and Chords.
  4. The class view Organizers only: attempts, practice time, current level and who needs a hand, per student — no e-mail or personal data exposed.

Schools with a group in the app: Cavallieri Escola de Música (Brazil) · MICA International Scholars (South Korea)

Frequently asked questions

What is this site?

A music education platform built as games: rhythm, sheet-music reading, intervals and chords by ear, and real music read from the score. It runs in the browser, on a computer, tablet or phone, with nothing to install.

Do I need an instrument?

No. Everything is answered on screen: rhythm on a button (or the space bar), notes on a drawn piano. If you have a MIDI keyboard you can use it in Reading, Real Music and Rhythm; an acoustic piano comes in through the microphone.

Is it for beginners?

Yes. Every game starts from zero and climbs by levels. Reading has a guide line that shows where the note sits, and a kids mode where each note has a color.

Do I need an account?

The first three levels of every game are open. From the fourth on, an account keeps your progress, puts you in the ranking and carries your practice to another device. You can sign in with Google.

What does the rhythm game measure?

Two numbers per note: whether you played at the right instant (onset) and whether you held it until it ended (duration). The margin is in milliseconds, and the score is the lower of the two.

How many levels does each game have?

Rhythm: 30 levels in 6 worlds. Staff Reading: 11 levels in 2 worlds. Intervals: 7 levels. Chords: 10 levels. Real Music: 4 public-domain pieces, plus any MIDI file you load.

How does it work for schools?

The school requests a group and gets an invite link. Students who join through it appear in the class ranking, and the organizer sees attempts, practice time and level per student. Details are in the For schools and teachers section.

Can I use my own sheet music?

Yes, as a MIDI file. The melody becomes sheet music moving across the screen, you plant the chords, and the song stays saved on your device — and in your account, if you want.

Is it for children?

Yes. Reading has a kids mode: each note has a color, the color also appears on the key, and it fades as the child learns. There is a page just about it: Sheet Music for Kids.

Which languages?

Portuguese, English and Spanish, each at its own address: aulademusica.com.br, absolutepitchclass.com and oidoabsolutoclass.com.
