1. A system for tuning a musical instrument, comprising:

  • a sound input device;

    a processing device operatively coupled to said sound input device; and

    a display operatively coupled to said processing device;

    wherein;

    said processing device executes computer readable code to create a first visual representation of a sound sensed by said sound input device for output on said display;

    wherein;

    said sound is generated by a musical instrument; and

    wherein;

    said first visual representation is generated according to a method comprising the steps of;

    (a) placing twelve labels in a pattern of a circle, said twelve labels corresponding to twelve respective frequencies, such that moving clockwise or counter-clockwise between adjacent ones of said labels represents a first frequency increment;

    (b) determining a target frequency;

    (c) identifying a first label corresponding the target frequency;

    (d) determining a sensed frequency which is equal to a primary frequency of said sound;

    (e) identifying a point on said circle corresponding to the sensed frequency;

    (f) creating a first line connecting the first label and the point, wherein;

    (1) the color of the first line is a mixture of a first color and a second color if the target frequency and the sensed frequency are separated by more than the first frequency increment and less than a first multiple of the first frequency increment;

    (2) the color of the first line is a mixture of the second color and a third color if the target frequency and the sensed frequency are separated by more than the first multiple of the first frequency increment and less than a second multiple of the first frequency increment;

    (3) the color of the first line is a mixture of the third color and a fourth color if the target frequency and the sensed frequency are separated by more than the second multiple of the first frequency increment and less than a third multiple of the first frequency increment;

    (4) the color of the first line is a mixture of the fourth color and a fifth color if the target frequency and the sensed frequency are separated by more than the third multiple of the first frequency increment and less than a fourth multiple of the first frequency increment; and

    (5) the color of the first line is a mixture of the fifth color and a sixth color if the target frequency and the sensed frequency are separated by more than the fourth multiple of the first frequency increment and less than a fifth multiple of the first frequency increment.
