Claim 1
Independent Claim
247 words
Music instruction apparatus comprising, a piano having a housing, a keyboard with a plurality of keys, and an electronic means producing an output corresponding to one or more depressed keys, music note display means including a panel having a grand staff indicia, a vertically disposed series of first light means corresponding to chord note information coordinated with said indicia, a series of second light means diagonally coordinated with said staff indicia and corresponding to an ascending scale note scale information, a keyboard representation located directly below the second light means, said keyboard representation having piano key indicia vertically aligned with second light means whereby a piano key indicia is vertically aligned with each ascending note, and a series of third light means associated with each of said keyboard indicia, a tubular support arm, means mounting said arm on the housing of said piano and connecting said arm to said display means for permitting rotational movement of said display means about a generally vertical axis through substantially 180° thereby to locate said display means in a selected adjustable position for ready viewing by persons proximate to the piano, and, electric circuit means selectively connected to said first, second, and third light means and to said electronic means of said piano, and including elements extending through said tubular support whereby, when a key of the piano is depressed, at least a selected one of the first, second, and third light means is turned on corresponding to said depressed key.
Claim 2
Dependent Claim
247 words
Music instruction apparatus comprising, a piano having a housing, a keyboard with a plurality of keys, and an electronic means producing an output corresponding to one or more depressed keys, music note display means including a panel having a grand staff indicia, a vertically disposed series of first light means corresponding to chord note information coordinated with said indicia, a series of second light means diagonally coordinated with said staff indicia and corresponding to an ascending scale note scale information, a keyboard representation located directly below the second light means, said keyboard representation having piano key indicia vertically aligned with second light means whereby a piano key indicia is vertically aligned with each ascending note, and a series of third light means associated with each of said keyboard indicia, a tubular support arm, means mounting said arm on the housing of said piano and connecting said arm to said display means for permitting rotational movement of said display means about a generally vertical axis through substantially 180° thereby to locate said display means in a selected adjustable position for ready viewing by persons proximate to the piano, and, electric circuit means selectively connected to said first, second, and third light means and to said electronic means of said piano, and including elements extending through said tubular support whereby, when a key of the piano is depressed, at least a selected one of the first, second, and third light means is turned on corresponding to said depressed key.
Claim 3
Dependent Claim
47 words
The music instruction apparatus of claim 1 wherein said arm includes a substantially horizontal body terminating at opposite ends in upwardly and downwardly directed legs merging respectively into said means connecting said arm to said display means and into said means mounting said arm on said piano.
Claim 4
Dependent Claim
40 words
The music instruction apparatus of claims 1 or 2 wherein said connecting means includes first and second relatively rotatable members respectively having circumferentially spaced stop means and a tab means engageable with said stop means at opposite limits of rotation.
Claim 5
Dependent Claim
63 words
The apparatus of claim 1 wherein: the electric circuit means includes a first on-off switch connected to the first light means, a second on-off switch connected to the second light means, and third on-off switch connected to the third light means, said first, second, and third on-off switches being separately operable whereby the first, second, and third light means can be selectively operated.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 wherein: the first, second, and third switches are mounted on said display means.
Claim 7
Independent Claim
