Description

[Detailed Description of the Invention] The present invention relates to a device suitable for teaching the relationship between the 1st key yoh and the 1st scale name yo with the keyboard by making the scale name of each key in a predetermined 1st key yo sound.

Conventionally, in order to display the note name of each key on keyboard instruments, C, C,
Write the letters ``, ``, etc., or write red, yellow, etc. for young children.
It was color coded, such as blue.

In this case, for example, an instrument that displays scale names in the C major scale cannot display scale names in another key such as G major, and teaching by visual means is extremely limited.

The object of the present invention is to improve the above-mentioned drawbacks and to provide an educational device equipped with a scale name generation circuit so that even when changing the key of 1/Y, it is possible to audibly teach the scale name of each key.

Embodiments of the present invention shown in the drawings will be described below.

In the drawing, KSW is a key opener provided corresponding to each key, and CSW is a switch switch that connects keys corresponding to derived sounds (black keys) such as C#, Db, etc. to the connecting line Ll of the main sound (white key). , L2...
・TSW is a transposition switch that is switched in conjunction with the key 1 when changing the key, SYG is a scale generation circuit, A and MP are amplifiers, and SP is a speaker.

Now place the transposition switch TSW on the C major terminal and press the white key of the main tone C, the corresponding key switch instrument KSW will close, and the scale name generation circuit SYG will generate the sound ``Toyo'' in the scale name generation circuit. 1 is driven and the stage name 1 TOYO is the speaker SP.
It is pronounced as the key 1 toyo of C in the key of C major.

Also, if you press the white key of the main note G, the scale name 1 so will be changed to 5.
Pronounced from YG5.

When you press the black key of the derived note C# between the main notes C and D, if the switching switch CSW is closed to the main note C side, the scale name of 1 toyo will be changed to the main note C#. When it is closed to the side, the floor name of Luyo is pronounced.

Therefore, it can be seen that the black key C# is one semitone higher than Toyo in the C major scale, and at the same time one semitone lower than Luyo.

Next, place the transposition switch TSW on the G major terminal and press the white key of C. The scale name of 1 Huayo will be sounded from SYG 4, and G
It turns out that the key is pronounced ``toyo''.

Although it is not shown in the diagram, if the pitch signal for the F white key is generated at the same time, the G major scale will have F# instead of F.
You will understand that the sound of is necessary, and your understanding of transposing scales will become more reliable.

Furthermore, if you move the transposition switch TSW to another terminal, you can understand scales in other keys, but since the wiring in the drawing is complicated, we will also describe the case of D major, which is displayed using two #s as the key signature. It is omitted when there are 3 or more or when 5 is used.

Furthermore, for the minor scale rather than the major scale, a similar device can be obtained by changing the transposing switch and its terminal connections.

Although any suitable scale name generation circuit SYG can be used, it is also possible to use one in which the vowel formant is mixed with the output of a white noise generator and a distorted sine wave waveform.

In this way, according to the present invention, it is possible to immediately determine which scale name each key on a keyboard instrument corresponds to in a predetermined 1st key by pressing the key after setting the transposing switch, and furthermore, by pressing the key after setting the transposing switch, It is extremely effective in practical use as an educational and training device in that it is easy to explain sounds (sounds).

Claims (1)

[Scope of utility model registration request] Each key has a key switch KS that opens and closes the key press signal.
W is provided to guide the key press signal obtained from the key switch KSW to each connection line after each of the key switches KSW, and from the connection line of the key corresponding to the derived sound to the switching switch C.
It is connected to the connection line of the main note via the SW, and the connection line corresponding to each key of the main note is led to each fixed contact of each transposition switch TSW provided in plurality, and the movable connection line of each transposition switch TSW is connected to the main note connection line through the SW. A stage name teaching device characterized in that each contact point is connected to a stage name generation circuit SYG which generates a stage name by voice.
