Abstract: A music tuner having both a contact sensing device and a non-contact sensing device to pick up the sound from a music instrument is so designed that it can automatically or manually select one of the sensing devices that is most suitable to the situation where the music tuner is used. The display screen of the music tuner is freely rotatable and pivotable, thereby allowing optimum view angle wherever the music tuner is placed. The display screen is configured to graphically represent the tune of the music instrument so that the user can easily and intuitively grasp the pitch of the sound as compared with a standard pitch. The music tuner is able to display the result by a normal display mode, a mirror display mode, or a combination of both modes.
