As parents are interested in music education for infants in these days, they require systems to help these infants to actively play music. In this paper, we propose a keyboard solo system using a real time hand recognition method. In order to enable the infants to use the system easily, the proposed system plays some sounds whenever the infants move their fingers on a paper piano. For the purpose of minimizing cost to play music, the proposed system utilizes a general PC with only a paper piano, a web camera, and a speaker. With the aim of precisely and efficiently recognizing both a hand and each key on keyboard, the proposed system divides a recognition step into a hand recognition step and a keyboard recognition step. Also, the hand recognition step considers only skin color, and the keyboard recognition step considers only black and white without other colors.

Nowadays the music market is getting bigger while students are losing their creativity because of the cramming education even in the music class. Based on the growing music market, we made a project for students to play the musical instruments more easily. The suggested program is different from any other system because, with this program, we can play the musical instruments if only we have a keyboard made of paper and Webcam, which made us save money. When an user put his finger on the paper keyboard, Webcam makes a sound recognizing the position of the finger on the keyboard. We can choose one instrument out of four; Piano, drum, base and guitar. With this system, we can get an opportunity to learn many sounds of musical instruments and make our own melody.
