Abstract (en)
[origin: EP0531782A2] The invention relates to a keyboard instrument for the natural tone system with at least one keyboard, the keys of which are assigned to the overtones in a predetermined sequence. The keyboard is according to the invention optimally adapted to the conditions of the natural tone system by sixteen keys being provided per octave, which are arranged and designed in such a manner that the natural tones can be played in succession in three playing planes. A particular feature of the invention is the nested arrangement of the keys in the three playing planes, exclusively the "harmony keys" being arranged in the front playing plane, the "melody keys" and a narrowed section of the "harmony keys" in the central playing region, and a narrowed section of the "melody keys", a further narrowed section of the "harmony keys" and the "chromatic keys" in the rear playing region. In each playing plane, the neighbouring key sections are in each case of the same width. <IMAGE>
