This intelligent keyboard instrument self learning system developed in this study consists of smartphone based learning application and keyboard-instrument auxiliary module. The keyboard instrument auxiliary module receives playing information of the instrument through smartphone application and bluetooth communication. Then the module shows it through LED display so that the relationship between the keyboard and scale could be easily recognized even for beginners. Also, this system provides saving function and analyzing function of user's performance data, making learning more effective.

In this paper, we propose a self instrument learning tool using a PC-based software and an external electronic keyboard instrument with USB interface to help primary school students to learn playing piano more easily and effectively. The PC-based learning software and the external electronic keyboard instrument interact through the USB interface. This tool has a help window to provide information how to play and support interesting game mode for exercise. The external electronic keyboard instrument receives a selective information through the USB interface and display it on LEDs and 7-segment for novices to easily know the relation between the notes and the positions in the keyboard. The external keyboard instrument can detect false inputs, display them on LEDs and on the information window. We implemented a self instrument learning system and our feasibility tests showed its validity of the self learning tool to improve the learning efficiency.

The music education improves the creative talent, social skills and academic achievement of the students. For the efficient music education, the learner centered study is highly recommended rather than the passive education, which supports self-control in selecting teaching materials, learning patterns and speed. For the successful self learning, it is requested to develop the collaborative educational learning tools, especially electronic collaborators such as H/W and S/W. Though there exist many commercialized electronic instruments and the PC MIDI based softwares, these tools have some limits and problems for the primary student to learn playing the musical instrument by himself. In this paper, we propose a supporting tool implementation method using an electronic keyboard instrument with USB Interface and PC-based software to help the primary student to learn playing the musical instrument. We implemented an electronic keyboard instrument module compactly and at low cost using a PIC18F4550 MCU. PC based software was developed to edit musical score, process the MIDI information, and interact with the electronic keyboard instrument module. This tool can offer a similar keyboard instrument environment and can be incorporated with self learning contents.

현재 컴퓨터 기반 악기 연주장치에 사용되는 입력장치로는 키보드, 마우스 등의 기본장치, 스마트폰에 널리 사용되는 터치방식, 그리고 전자악기의 MIDI 인터페이스 등과 같이 다양하다. 본 연구에서는 Kinect의 3차원 영상데이터를 이용하여 효율적으로 손가락 움직임을 검출하는 방법을 제안하고 이 정보를 이용하여 피아노 연주 입력장치를 구현함으로써 PC기반 피아노 연주시스템 구현의 편리성을 보였다.

Piano is one of the most beloved instruments in the world and is used a lot for children to learn music because it is simple to play. As a result, various products for children, such as toy pianos, were released. However, there is a lack of piano skills for music education, such as how to play the piano or read the score. To solve this problem, in this paper, we propose a game-style educational piano using Arduino. It is expected to capture fun and education at a low price by scoring points by displaying the score on the LCD screen and pressing the keyboard according to the timing of playing the note.
