Abstract
Abstract A device for teaching music comprising, in combination, a set of pegs or keys subdivided into seven groups corresponding to the seven musical notes, a set of cards obtained by a sheet material, each card containing a musical passage consisting of coded holes corresponding to the notes of the passage, and means for reproducing the sounds corresponding to each of the seven notes when the respective pegs selectively associated with each hole are first introduced into said holes, and then sequentially depressed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
74 words
A device for teaching music, comprising, in combination, (a) a set of pegs subdivided in seven groups corresponding to the seven musical notes; (b) a card containing a musical passage consisting of coded holes corresponding to the notes of said passage; and (c) means for reproducing the sounds corresponding to each of the seven notes when the respective pegs selectively associated with each hole are first introduced into said holes and then sequentially depressed.
Claim 2
Independent Claim
74 words
A device for teaching music, comprising, in combination, (a) a set of pegs subdivided in seven groups corresponding to the seven musical notes; (b) a card containing a musical passage consisting of coded holes corresponding to the notes of said passage; and (c) means for reproducing the sounds corresponding to each of the seven notes when the respective pegs selectively associated with each hole are first introduced into said holes and then sequentially depressed.
Claim 3
Dependent Claim
36 words
A device as claimed in claim 1, wherein the coding of the holes carried by the card and of the associated pegs is such that each hole will accept only the peg representing the appropriate note.
Claim 4
Dependent Claim
37 words
A device as claimed in claim 1 or 2, wherein said code consists of at least one notch or projection carried by each peg, to which correspond equal projections or notches in the holes of the card.
Claim 5
Dependent Claim
41 words
A device as claimed in claim 1, wherein the "sharp" and "flat" variants of each note are differentiated with respect to the natural tonality by a different color of the peg, and of the circle surrounding the hole through the card.
Claim 6
Dependent Claim
35 words
A device as claimed in claim 1, wherein said sound reproduction means comprises a printed circuit associated with a sound generating system, operated by contact carrying bridging members located at the bases of said pegs.
Claim 7
Dependent Claim
40 words
A device as claimed in claim 5, wherein the various contacts of said printed circuit are located under an apertured plate whereon is located said card so as to leave available only the holes corresponding to those of the card.
Claim 8
Dependent Claim
42 words
A device as claimed in claim 5, wherein each sound is generated due to the pressure of the corresponding peg against the action of a resilient means which interrupts the contact of said bridging member as soon as the peg is released.
Claim 9
Dependent Claim
42 words
A device as claimed in claim 1, wherein said sound reproduction means comprises a set of compressed air ducts associated with a corresponding set of sound generating elements, and selectively operated by a projecting element located at the base of each peg.
Claim 10
Dependent Claim
27 words
A device as claimed in claim 8, wherein said projecting element is located in a different position dependent on whether the note is natural, "sharp" or "flat."
Claim 11
Dependent Claim
47 words
A device as claimed in claim 8, wherein said valve comprises a conical pin, inserted into a communication hole, and pushed to the closure position by spring means acting on a longitudinal member U-shaped in cross section, associated with each blow pipe, and located under said member.
Claim 12
Dependent Claim
52 words
A device according to claim 1, wherein said air ducts are defined by a set of parallel blow pipes, obtained by a corrugated sheet of resilient material, and the compressed air inflow is controlled by a projecting element which opens a valve causing the compressed air to communicate with said blow pipe.
Claim 13
Dependent Claim
56 words
A device as claimed in claim 1, wherein said sound reproduction means comprises a set of horizontal rods, associated with each sound reproduction element, slidable under the control of each peg against the action of a spring means biasing the rod to a position closing the outlet hole for the air from said sound generating element.
Claim 14
Dependent Claim
42 words
A device as claimed in claim 12, wherein said rods are connected to the casing by pairs of short links, slightly inclined with respect to the vertical, whereby the pressure on said peg is converted to horizontal sliding movement of the rod.
Claim 15
Dependent Claim
42 words
A device as claimed in claim 12, wherein a said spring means is mounted on one end of each rod, the other end of each rod being provided with a packing for abutment against said air passage for the sound generating element.
Claim 16
Independent Claim
113 words
A device for teaching music, comprising in combination, (a) a set of pegs subdivided in seven groups corresponding to the seven musical notes; a card containing a musical passage consisting of coded holes corresponding to the notes of said passage; and (c) means for reproducing the sounds corresponding to each of the seven notes when the respective pegs selectively associated with each hole are first introduced into said holes and then sequentially depressed; (d) said code consisting of at least one notch or projection carried by each peg, to which correspond equal projections or notches in the holes of the card, whereby each hole will accept only the peg representing the appropriate note.
Claim 17
Independent Claim
113 words
A device for teaching music, comprising in combination, (a) a set of pegs subdivided in seven groups corresponding to the seven musical notes; a card containing a musical passage consisting of coded holes corresponding to the notes of said passage; and (c) means for reproducing the sounds corresponding to each of the seven notes when the respective pegs selectively associated with each hole are first introduced into said holes and then sequentially depressed; (d) said code consisting of at least one notch or projection carried by each peg, to which correspond equal projections or notches in the holes of the card, whereby each hole will accept only the peg representing the appropriate note.
