Abstract

In order to play the piano or electric organ, you should look at the score and quickly identify the notation on the score and press the keys accordingly. Therefore, if the public does not take a lesson for a certain period of time, it is difficult to play. Using the seven segment array provided by, you can indicate the position of the piano keys for the specific notes shown in the score and the number of the fingers to be used, and specify which of the two hands to use by the color of the two-color seven segments. Since the user can practice playing music by himself, it can be conveniently used to learn the piano.

Description

Self-Learning Piano Using Seven Segment Displays}

In order to play the piano or electric organ, you should look at the score and grasp the notation on the score quickly and press the keys accordingly. Therefore, the general public has difficulty in playing if the lesson is not received for a certain period of time.

In some designs, the positions of the keys to be pressed are indicated by LEDs or lamps, but the hand and finger numbers are not specified among the left hand and the right hand to press the notes. There is a limit to this, and therefore, the appearance of a piano capable of supporting this is required.

In order to solve the inconvenience as described above, the present invention has a seven-segment arrangement in the form of a keyboard at the top of the keyboard to play the piano, the position of the piano keyboard and the number of fingers to be used for each specific note of the song to be played here In addition, the purpose of the present invention is to provide a piano which allows self-teaching by the player alone by practicing according to the seven-segment segment by designating the hand to be used in both hands by the color of the two-color seven segment.

10: piano 20: self-teaching device

21: Seven segment 22: Seven segment (red light, for right hand position display)

23: Seven segment (green light, left hand position display)

Piano having a self-teaching function using the seven segments in the present invention for achieving the object as described above has a seven-segment arrangement identical to the arrangement of the keyboard at the top of the piano keyboard with the position of the piano keyboard to be pressed here The left hand / right hand is displayed so that the number of the hand to be used and the number of fingers to be used at this time can be configured to allow the player to play as directed by the seven segments.

Referring to the preferred embodiments of the present invention using the accompanying drawings as follows.

Detailed structure of the piano having a self-teaching function using the seven segments according to the present invention is configured in the form of a self-teaching device 20 attached to the general piano 10 as shown in FIG. The device unit 20 constitutes a row of two-color seven segments 21 that are identical to the keyboard arrangement of the piano, and the seven segments 23, which are displayed in red, are the finger numbers of the right hand, and the seven segments 22, which are displayed in green, And to indicate the finger number of the left hand.

The hardware structure of the self-teaching piano is as shown in FIG. 2, and the seven segment part 30 capable of displaying the position of the key to be pressed and the hand to be used in two color numbers, for driving it with an appropriate current. A segment driver 31, a color selector 32 for selecting the color of the number to be displayed on the seven segments, a data latch unit 33 for latching the data to be displayed on each seven segment from the control unit, specifying when data is outputted A segment address decoder 34 for selecting a segment, a memory unit 37 storing performance data for various piano songs, a button interface 36 for selecting various functions such as an operation speed of the self-teaching apparatus, selection of songs, and the like. ), The PC interface unit 38 for communication with the PC for the purpose of accessing a database stored on the PC or the web, and the entire system. It is comprised by the control part 35 which is in charge of control.

The software operation of the self-teaching piano according to the present invention consists of the length of the note to be played, the position of the key to be pressed, the number of hands and fingers to be used after initializing the system as shown in FIG. Read the data of the performance song (S41), set the timer according to the note length among the data (S42), convert the number data of the used finger to be displayed by BCD-seven segment conversion (S43) and export it to the output port. It outputs to the driver (S44) and outputs the position data of the keyboard to the output port (S45) so that the data can be latched at the corresponding position, and when the timer is terminated by checking the end of the timer (S46), all data is processed. Repeat the above steps until the data of the song you want to play is displayed in sequence in the seven segments.

As described above, the piano having the self-teaching function using the seven segments in the present invention uses the seven segment arrangement provided in the form of a key on the upper portion of the piano keyboard, and the position of the piano keyboard to be pressed for each specific note of the song to be played. If the number of the finger is displayed and the hand to be used between the two hands is designated by the color of the two-color seven segment, the player can self-learn the piano by himself according to the instruction of the seven segment.
