A Piano is a popular musical instrument. Development of playing piano requires frequent and suitable practice. However, the learners often have difficulty on space and time for practice due to less portable size and weight of the piano. In this article, a portable and virtual-reality (VR) based self-training system of the piano is proposed, which is installed on a standalone see-through Head-Mounted-Display (HMD). A learner wearing the HMD can see both of superimposed virtual piano keyboard and virtual his/her own fingers. According to his/her keying by the fingers, the system represents the situation acoustically. Evaluation of training outcome (number of incorrect keying) and subjective assessment shows advantages of the proposed system in comparison of a piano playing application on a tablet device.
