AUTOMATIC VISUAL TEACHING DEVICE FOR THE LEARNING OF MUSIC OR COMPONENT PARTS THEREOF An automatic visual music teaching device for displaying the structure of coded chords. The device comprises a plurality of actuable switches for selecting a desired coded chord. Signals associated with the actuated switches are temporarily stored and are indicative of the desired coded chord to be visually displayed. A further switch is activated to transfer the stored signals indicative of the desired coded chord to a decoding circuit. The decoded circuit feeds a memory system to select in a matrix the composite parts of the desired coded chord in accordance with a coded data signal sent to it by the decoder whereby the composite parts of the desired coded chord are visually indicated on a visual display element. The method of visually teaching the component part structure of musical coded chords comprises simply the step of selecting switches having coded marking thereon representative of musical notes in major and minor tones and corresponding to a desired coded chord for transferring a corresponding signal to a temporary storage circuit. A transfer switch is then depressed to obtain the visual indication of the composite parts of the desired coded chord for learning purposes.
