Harmonic Wheel by Luis Nuño in Spanish

The new instrument for musicians. The Harmonic Wheel is a new representation of Sounds, where the Consonance Relationships among them are clearly shown. It is, therefore, a powerful tool for the comprehensionof Music Theory and Harmony. The Harmonic Wheel has been developed by considering 2 kinds of Consonant Relationships:Consonant Intervals (2 note consonances) and Consonant Chords (3 note consonances).Contains 2 discs, one of cartboard and another one of plastic that can turn one around the other one. Among other characteristics, it offers a complete and outlook vision  of the relations that exist between all the tonalities. level: medium and higher
