Abstract
Abstract This invention relates to an electronic device for teaching musical note recognition wherein notes represented by lights are randomly displayed on a display screen, the screen having selected musical clefs thereon. The notes are displayed in a random manner so that response must be to the notes themselves rather than a recognized display pattern. There is also included in the device the capability, at the operator''s option, of identifying the notes as they are displayed, and further of selecting a musical key to which the displayed notes are to relate. Note and key identification are also represented by lighted symbols displayed on the display screen with a note identification symbol being displayed with each note.

Claim 3
Independent Claim
62 words
A device for teaching musicAl note recognition comprising a display screen, means on the display screen defining selected musical scales, a series of electrically activated means representing notes on the musical scales, electric circuit means, said electric circuit means including means for generating update signals and means responsive to said update signals for automatically activating random ones of said note representing means.
Claim 4
Independent Claim
62 words
A device for teaching musicAl note recognition comprising a display screen, means on the display screen defining selected musical scales, a series of electrically activated means representing notes on the musical scales, electric circuit means, said electric circuit means including means for generating update signals and means responsive to said update signals for automatically activating random ones of said note representing means.
Claim 5
Dependent Claim
21 words
The device of claim 1 wherein the electric circuit means further comprises means for generating said update signals continually and automatically.
Claim 6
Dependent Claim
23 words
The device of claim 2 wherein the note representing means are a series of lights which when activated represent notes on the screen.
Claim 7
Dependent Claim
53 words
The device of claim 2 further comprising means for deactivating the means for continually and automatically generating the update signals, and manually advancing means for advancing from the generation of one update signal to another, the electrical circuit means further comprising means for randomly activating a note representing means with each manual advance.
Claim 8
Dependent Claim
25 words
The device of claim 2 wherein the electric circuit means further comprises means for varying the frequency at which the the update signals are generated.
Claim 9
Dependent Claim
24 words
The device of claim 1 including means responsive to the electrical circuit means for indicating the identity of the notes as they are displayed.
Claim 10
Dependent Claim
25 words
The device of claim 1 including means responsive to the electrical circuit means for designating a key to which the displayed notes are to relate.
Claim 11
Dependent Claim
44 words
The device of claim 7 wherein the key designating means further comprises a series of sharp and flat symbols positioned relative to the scales to indicate selected keys, and means for illuminating selected ones of said sharp or flat symbols, thereby indicating the key.
Claim 12
Dependent Claim
145 words
The device of claim 1 wherein the electrical circuit means further comprises means for randomly generating a first series of oscillations, means for randomly generating a second series of oscillations, means for generating a first signal indicative of the number of oscillations of said first series generated during a selected first time interval, means for generating a second signal indicative of the number of oscillations of said second series generated during a second time interval, means responsive to said first and second signals for activating a particular note representing means, each of said note representing means being activated in response to a given set of first and second signals, and means for updating said first and second signals at selected intervals in response to said update signals, each time activating a note representing means, whereby said note representing means are activated in a random manner.
Claim 13
Dependent Claim
96 words
The device of claim 9 wherein the note representing means are divided into a select number of groups, a note representing means in each group being responsive to said first signal, and a selected group being responsive to said second signal, there being at least as many possible types of first signals as there are note representing means in each group, and at least as many possible types of second signals as there are groups, whereby for a given set of first and second signals, a given note representing means in a given group is activated.
Claim 14
Dependent Claim
40 words
The device of claim 10 further comprising means for restricting the activation of a note representing means to selected groups, and for activating a note representing means within the selected groups with each update of the first and second signals.
Claim 15
Dependent Claim
45 words
The device of claim 9 wherein the first and second signal generating means further comprises counter means for counting said first and second series of oscillations separately, and generating said first and second signals, respectively, as indicative of said counts for the respective time interval.
Claim 16
Dependent Claim
46 words
The device of claim 12 further comprising a tempo generator which produces oscillations said update signals at a selected rate, and means for updating said counters to begin Recounting said first and second series of update signals in response to the oscillations from the tempo generator.
Claim 17
Dependent Claim
34 words
The device of claim 13 wherein the electric circuit means further comprises means for varying the rate of signals from the tempo generator, thereby varying the rate at which notes appear on the screen.
Claim 18
Dependent Claim
51 words
The device of claim 9 wherein the means for randomly generating said first and second series of oscillations further comprises a diode, means to bias the diode to generate therefrom random noise, and means for generating said first and second series of oscillations in response to the amplitude of said noise.
Claim 19
Dependent Claim
38 words
The device of claim 9 further comprising manually advancing means for advancing from the display of one note to another, the electrical circuit means further comprising means for randomly activating a note representing means with each manual advance.
Claim 20
Dependent Claim
24 words
The device of claim 9 including means responsive to the electrical circuit means for indicating the identity of the notes as they are displayed.
Claim 21
Dependent Claim
25 words
The device of claim 9 including means responsive to the electrical circuit means for designating a key to which the displayed notes are to relate.
Claim 22
Dependent Claim
40 words
The device of claim 18 wherein the key designating means further comprises a series of sharp and flat symbols positioned relative to the scales to indicate selected keys, and means for illuminating selected ones of said sharp or flat symbols.
