Description

[Detailed description of the invention] Conventionally, staff paper is formed by marking double-line linear electrodes corresponding to each line, between lines, and separate lines of the staff on a musical score, and each electrode is Musical musical instruments have been known that are connected to operating terminals of sound sources that generate the corresponding scales, and when each electrode is touched by a separately provided probe, the sound sources of the corresponding scales are activated to generate musical instrument sounds. .

In this case, since the electrode is long and thin, the resistance valve at the operating terminal 1 of the sound source differs depending on the position touched by the probe, which has the disadvantage that good operation cannot be expected.

The present invention provides an electrode for a musical instrument that eliminates these drawbacks.

Fig. 1 shows an embodiment of the present invention.
On the top, each electrode a1a2... is formed as wide as possible leaving a minimum gap necessary for mutual insulation, and only the part necessary to touch with the probe 7 is exposed above this. Then, insulating paint b1b2... is applied to other parts.

Since the electrodes are wide in this way, the difference in the resistance valve depending on the position touched by the probe 1 can be ignored, so the length of the staff can be made longer than before, and the exposed parts of each electrode can be separated from each other by the insulating paint. Since they are spaced apart, there is no chance of accidentally touching two electrodes at the same time.

Each electrode ala2... is connected to the same number of operating terminals d1d2... of the sound source 2, respectively.

The sound source 2 is provided with one operating terminal 3, and the probe 7 is connected to the operating terminal 3 by a lead wire 8.

The sound source 2 is connected to the plurality of operating terminals d1d2...
When any one of them is connected to the one operating terminal 3, the sound of the corresponding scale is emitted.

It is convenient to make the electrodes black and the insulating paint white, as this gives the same appearance as a normal musical score.

That is, in this case, the portion corresponding to the line will be a black line, similar to a normal musical score, and the portion corresponding to the line will be a dotted line.

FIG. 2 shows a state in which musical scores have been written on the musical score paper obtained in this manner.

Another advantage is that by color-coding the insulating paint for each pitch, it can be made easier for beginners to understand.

Even beginners can perform according to the musical score by writing musical notes on the musical score paper made in this manner and touching the musical notes with the probe 7.

In Fig. 1, electrodes a1'a2'... are provided in addition to electrode ala2..., and each electrode is connected in parallel like 8□, □la2, and a2'. This makes it suitable for playing relatively long songs.

In this case, connections C1, C2 for parallel connection...
... can be easily connected in parallel by printing wiring on the back side.

Further, in this embodiment, a display board 4 and changeover switches E, E2, etc. as shown in FIG. 3 are provided.

That is, for songs in keys other than C, it is necessary to raise or lower the corresponding note by a semitone based on the change symbol.

In this embodiment, such operations can be set in advance using a changeover switch.

That is, the symbol # (sharp) or (flat) is written on the display board 4 at a predetermined position corresponding to each key, and
Light emitting diode F1. F1/, F2゜F2'...
・ is embedded.

On the other hand, since a plurality of changeover switches are provided corresponding to the # arranged in each scale, the changeover switch E1 can be changed to # or
When you tilt it to the side, the # or light-emitting diode located at the "C" position on the display board will light up, and the "C" emitted by the sound part will also light up.
The pitch of the notes is also raised or lowered by a semitone.

The same is true for the other changeover switches, and when the light emitting diodes # or # are lit at the corresponding positions, the pitch of the sound produced by the sound generating section is raised or lowered by a semitone.

Therefore, by simultaneously switching predetermined ones of the above-mentioned switches, a performer can play music in any key by touching the electrodes with the probe according to the musical score.
