Abstract:
1. A tuning device for tuning a musical instrument to at least one target pitch, comprising: a converter converting vibrations representative of a tone produced in said musical instrument to an electric signal representative of said vibrations; an inspector connected to said converter, and comparing an actual frequency of said tone with a target frequency of said at least one pitch to see whether or not said tone has said at least one target pitch for producing a positive answer or a negative answer; an image producer connected to said inspector, producing an image expressing said positive answer or said negative answer on a visual interface, and notifying users of difference between said actual frequency and said target frequency by making said image produced at said negative answer different from said image produced at said positive answer; and a resolution controller connected to said image producer, requesting said image producer to vary a resolution of said image so as to magnify a part of said image produced on said visual interface at said negative answer, and establishing a window time period for said image, wherein said tuning device further comprises a time keeper connected to said inspector and said image producer and causes said inspector repeatedly to produce said positive answer or said negative answer so that said image producer produces said image from basic images through superimposition of said basic images on said visual interface at time intervals longer than a window time period occupied by each of said basic images.
