Abstract

The present invention relates to a digital keyboard musical instrument arranged vertically and horizontally, and more particularly, to a keyboard musical instrument that facilitates chord playing by displacing keys (switches).

Description

Keyboard for chord input {CHORD KEYBOARD}

The present invention relates to a digital keyboard musical instrument, and more particularly, to a digital keyboard musical instrument that can easily play chords intuitively by displacing keys.

Since a piano-type keyboard, which is a conventional keyboard instrument, is composed of white keys (warms) and black keys (half notes), in order to play a chord, the positions of the keys required for the chords must be known in advance. Therefore, for accompaniment, it is inconvenient to memorize the positions of the chords for a long time. An object of the present invention is to arrange the arrangement of chords in units of 3 degrees so that the chords can be intuitively played.

As shown in Fig. 1, the keys (switches) are alternately connected, and the intervals between the rows of the keys are arranged semitones, and the intervals between the columns are alternately arranged in long / short 3 degrees.

When the present invention is applied, it is possible to intuitively play a chord because the keys (switches) to be pressed when trying to play a chord are located in the same row.

1 is a perspective view of a keyboard to which the present invention is applied. Rows are arranged at semitone intervals, and columns are arranged at intervals of three degrees each.

If you want to press the 'Dmaj7' chord, you'll need to press Dmaj7's D, Gb, A and Db. In the case of this keyboard, since the configuration sounds of the above chords are arranged in one row as shown in [Fig. 2], the chords can be intuitively played.

And if you want to press chords like 'Dm7' by changing the chords a little, you need to press D, G, A, and C, which are the components of Dm7. It's easy to play because it exists.
