Abstract

A musical instrument with two or more classes of pitches where at least one class is a diminished chord extended over an arbitrary number of octaves, and another class is another chord extended over the same span of octaves. The pitches of the second class of pitches are interlaced with the pitches of the diminished chord of the first class of pitches. Additional classes are chords similarly interlaced with other classes, with one class of any interlaced pair of classes being a diminished chord.

Claims

1. A musical keyboard for generating tones, comprising:

a first register of keys for generating a first class of pitches including a diminished chord extending over an arbitrary number of octaves;

a second register of keys for generating a second class of pitches;

the pitches of the second class of pitches being interlaced with the pitches of the diminished chord of the first class of pitches;

wherein the classes of pitches are assigned to mechanical actuators arranged in groups by class, in which the activation of an actuator causes the production of a musical pitch within the mechanical actuators;
