Abstract: An algorithmic combo-instrument slide ruler comprising one common part working in cooperation with two interchangeable parts selected from separate multitudes of unique yet related parts. An opaque slidable combo-instrument tuning card is selected having thereon information resembling a stringed instrument, having fingering positions represented in equivalent keyboard keys laid out in a multi-tier octave isolating manner. A semi-opaque rectangular sleeve housing comprising of parent and dependant child windows arranged in a reticulated manner, working within stationary alignment with a selected semi-opaque scale or mode insert comprising of a scale or mode relevant predetermined array of finger position windows and dependant finger position data boxes, allows for a visible and semi-visible view of the combo-instrument card there through, showing available fingering positions through parent windows and music reference information through relevant child windows.

Abstract: A music teaching system is provided, comprising at least two musical instruments, each instrument having a mechanism for producing a musical note when the means is activated, each such mechanism being marked by a color corresponding to the particular musical note produced by the mechanism; and at least two display vehicles for displaying a combination of the colors. The invention may be accomplished using colored hand bells for the instruments and cards for the display vehicles.

Abstract: A teaching aid simplifies the understanding and practicing of the inversions of the major triads of the diatonic scale by utilizing a series of insert cards which slide into a simulated keyboard and read up vertically duplicate sets of the scale tones of the triad beginning with the underlying keyboard tone. In contrast with the usual method of inversion indication, wherein sequential indicia point out inversions on the keyboard itself, or on a horizontal scale, by reading up vertically rather than horizontally the student is able to easily see the inversion arrangement without confusing it with the keys that he is playing.

Abstract: The invention is in the field of musical learning and playing devices, and particularly relates to keyboard instruments. A plurality of cards are provided each of which defines a forward pocket and each of which spans an octave on the keyboard. These cards are positioned adjacent to one another across the breadth of the keyboard, and a second group of insert cards are inserted into the pockets defined by the first cards. These second cards may be one of several types, but in any event they display indicia which register with keys on the keyboard, and each of these cards also includes a laterally extended tab which engages the adjacent card by overlapping same so that the entire line of cards is stationary as a unit rather than being completely separate.

Abstract: A teaching device for use with an organ, supported on the upper keyboard, with timed motor means to move an apertured record sheet between a light source and fiber optic connectors which transmit light signals to the fiber optic ends located over keys of the lower chord keyboard and through a sideways extending housing to fiber optic ends located over the keys of the upper melody keyboard in accordance with the placement of the apertures on the moving record sheet.
