Description

The Musical Abacus integrates the main concepts in Music Theory, relating them in a logical and ordered way.For beginners, simple to use, for those without prior knowledge to reading music. It consists of two rotating discs,one being cardboard and the other plastic. Both discs are 12-sided polygons (or dodecagons).

This is due to the fact that there are 12 different musical notes and, therefore, 12 Major Keys, 12 minor Keys,12 Major Chords, 12 minor Chords, etc.
In each of the 12 positions that can be selected you obtain:
A Major Key and its relative minor.

The corresponding Major Scale and its relative minor.

The Intervals from the Tonic of the Major Scale.

The 3 Main Chords in both Keys and their Arpeggios.

The Harmonics produced by the Tonic of the Major Key.

The corresponding Key Signature for both Keys.
