Description

Fig.b

This invention relates to a musical instrument keyboard.

The purpose of the invention is to enhance the performance capabilities.

FIG. 1 shows the keyboard of a musical instrument with a hexagonal shape of the surface of the keys, a plan view; in fig. 2 - keyboard of a musical instrument with a quadrangular shape of the surface of the keys, 1 plan view; in fig. 3 is a view A of i in FIG. 1 and 2; in fig. 4 — node I in FIG. one; in fig. 5 shows unit II in FIG. 4, examples of execution.

,one

The keyboard of a musical instrument contains the keys 1 „made in the form of polyhedra, on the side graphs -: / н х of each of the keys I are made | the protrusions 2 and valleys 3 for placing i in the corresponding valleys 3 and the protrusions 2 of adjacent keys 1. The top edge of the key 1 is streamlined, and the side faces are protrusions 2 and the depression 3, while the projections 2 of the side edge of one key 1 are in the depressions 3 of the adjacent side face of another key 1, on the contrary, the projections 2 of the other key 1 are located in the depressions 3 of the first key 1.

The keyboard of a musical instrument works as follows.

When one key 1 is pressed, the projections 2 of its lateral edges move in the valleys of the 3 lateral faces of the adjacent keys 1, and the valleys 3 move relative to the projections 2 of the adjacent lateral edges of these keys 1, which allows one to confidently press one v. finger two keys 1 at the same time, Q since even if the finger does not fall exactly on the border of two keys 1 (and let's say on the edge of one of the keys 1), it will still press (capture). the projections 2 of the other key 1 and it will be pressed 4 seconds together with the first key 1. Such a design of the keys 1 allows you to confidently slide your finger from key to key, since key 1 is not pressed with its projections 2

smoothly moves to the pressed key, while the vertical sides of the projections 3 of the unpressed key 1 are always below the surface of the pressed key 1.
