Abstract

PROBLEM TO BE SOLVED: To provide a unit and method for guiding a performance at a low cost although the performance guide of right-hand and left-hand parts is given to a player who plays music having a plurality of parts. SOLUTION: A CPU 3 of a keyboard musical instrument 100 outputs musical sound data corresponding to tracks of right-hand part data 51a and left-hand part data 51b to a sound source 7 to reproduce the music. At this time, the CPU 3 generates an illumination signal according to operation guide data corresponding to the tracks of the right-hand part data 51a and left-hand part data 51b and outputs the signal to a guide part 4, which makes LEDs corresponding to the right-hand part blink in normal blinking pattern and LEDs corresponding to the left-hand part blink in reverse blinking pattern. Further, the CPU 3 judges whether correct playing operation is done at a playing operation part 1 and advances to a next track when the correct playing operation is done.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance guide device and a performance guide method for assisting a master in playing a musical instrument.

[0002]

2. Description of the Related Art Conventionally, there has been provided a performance guide device for a keyboard musical instrument or the like, which displays a guide for practicing musical instrument performance.

For example, as a keyboard instrument, a memory in which a plurality of pieces of music data are recorded is built in, and specific music data is read from this memory, and a key pressing instruction for causing a key to be pressed to emit light based on the music data is provided. For example, there is a light emitter provided for each key. In this keyboard instrument, the player is informed of a key depression instruction (performance operation) by sequentially emitting light from the light emitters. Also, at this time, as a key depression instruction,
When a key to be pressed is guided by a light emitter of one color, a key to be pressed with the right hand (that is, the right hand part) and a key to be pressed with the left hand (that is, the left hand part) are classified. There are cases where performance guides are performed using two-color light emitters.

[0004]

However, when playing a song having a plurality of parts (for example, a melody and an accompaniment), as described above, the key to be depressed is guided by the light-emitting body of one color. In this case, since the right-hand part and the left-hand part are shown at the same time, there is a problem that the boundary between the right-hand part and the left-hand part is difficult to understand. Further, when the keys to be pressed are classified into the right-hand part and the left-hand part and the performance guide is performed by the two-color light emitters, since each part can be shown in a different color, the right-hand part and the left-hand part can be shown. While it has the advantage that the boundaries are easy to understand,
There was a problem that it was costly.

An object of the present invention is to provide a performance guide device and a performance guide method which, while playing a piece of music having a plurality of parts, allow the performer to easily understand the right hand part and the left hand part while keeping the cost down. Is to provide.
