Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides performance practice by means of display information for musical tones required for self-study of keyboard musical instruments, floor name guides by voice, and means for instructing practice instruction information for self-study by voice. It relates to an electronic musical instrument that enables you to effectively study multiple lessons according to your level.

[0002]

2. Description of the Related Art Conventionally, as a means for practicing a keyboard musical instrument, a device for indicating a key depression such as a melody or a code with an LED has been considered. There is also a device in which a floor name is pronounced by voice and the floor name (for example, Do, Fa, Si, etc.) that is pronounced is heard and played.

[0003]

However, in the above-mentioned conventional musical instrument playing means, the practitioner operates by following the key in accordance with the instruction of the LED displayed corresponding to the key, or the floor name. Can only be pronounced by voice, and, for example, while listening to voices such as do, mi, and so on, the corresponding key can be pressed to perform. For this reason, there is a problem in that it is impossible to practice each step with the right hand, the left hand, and both hands for practice.

The present invention solves the above-mentioned problems of the prior art by providing voice guidance for each melody part performance, code / chord performance, two-handed performance, etc. required for practice in each of the right hand, left hand, and both hands. It is an object of the present invention to provide an electronic musical instrument that can be practiced according to a musical piece by automatically controlling the designated display of the keyboard and the pronunciation of the sound by the floor name.

[0005]

In order to solve this object, an electronic musical instrument of the present invention has a keyboard, a musical tone generating means, a storage device storing performance information, and a key performance to be operated from the storage device. It has an instruction means for reading out information, designating and displaying it, and a means for reading out a floor name or a code name of a key to be operated from the storage device and generating a corresponding voice.

[0006]

With this structure, the performance information necessary for self-study of the keyboard performance is used to display the designation display by the instruction means corresponding to the keyboard, and the floor name and chord corresponding to the key are audibly taught. You can practice at each step, and you can enjoy learning about the musical instrument without any particular knowledge of the musical instrument or understanding of the musical score.
