Music – easy as 123.

Play, sing and write music together — at home, in the classroom or in a hall full of people. No lessons needed.

Try it — hold a chord, slide across the numbers

Red numbers are natural. Blue numbers are flat, and underlined. A square is the octave below the 1, a circle the octave above — and green is the colour of harmony.

Four ways in

In the classroom, at home, or in a hall.

How it works

Numbers, not notation.

1

Pick a Tonal Centre

Every song starts from home. Numbiano's moveable system means the same numbers work from any Tonal Centre — learn once, play everything.

6

Read red and blue

Red numbers are natural, blue numbers are flat. No sharps, no five-line stave, no barrier between you and the music.

7

Sing it, play it, share it

Each number has its own sung vowel, so your voice and your fingers learn together — solo, with your family, or with a whole room.
