Disclosed are a method and a device which embody a virtual guitar on mobile devices like a cellular phone, etc. Actually, a mobile device screen such as a cellular phone screen, is too small to display a long finger board without causing difficulties when playing. Accordingly, the object of the present invention is to display a whole finger board within a small screen in mobile devices without any difficulties when playing and additionally, require the same technique when playing it as a real guitar. The finger board is directly played with a finger on a mobile device screen that is a touch screen supporting a multi-touch operation. Since a movement recognition sensor is attached inside the mobile device and the finger board on the screen is synchronized with the longitudinal movement of the fingers, the finger board can move in the same direction and at the same speed as the movement of the fingers. The mobile device is equipped with the movement recognition sensor and the touch screen supporting a multi-touch operation, whereon the player plays chords on the displayed finger board. Accordingly, the screen displays the part of the finger board that corresponds to the speed and movement of the fingers when the movement recognition sensor senses the collinear movement of the fingers to the finger board. Therefore, the disclosed guitar may display the whole actual finger board of a guitar naturally without any limitations and require the same technique when playing it as a real guitar through mobile devices with a screen as small as a cellular phone screen, without an auxiliary device.
