• the apparatus of this invention comprises a simulated fingerboard and a set of movable note index units that are cooperatively and concurrently used to visually illustrate and practice the proper location of finger positions for each of the notes in each of several keys of operation of a stringed instrument. It also provides an apparatus and method of visually illustrating the sequence of changes of finger positions shown by the movable note index units— between the various keys and note sequences.
• the apparatus provides for firmly yet releasably holding, longitudinally displacing and replacing note index units with one hand of the student while the other hand of the student holds the simulated fingerboard of a stringed instrument in normal operating position of that stringed instrument.

• the player as 74 presses the center of the top of a unit as 102 or 103 on the fingerboard base 40 to simulate press ing the fingerboard of the instrument 41 at a finger position to produce a note as B or C respectively on the G string of violin 41.
• Units 102 and 103 are only exemplary as the top surfaces of other tone index unit panels are pressed to similarly simulate finger positions on the fingerboard 42 for other notes.
• the significant factor in such operation is that when the center of the top surface of the panel of each unit is pressed to simulate and practice playing on the instrument 41 the flat prism bottom surface matches the flat base top surfaces and provides a rigid support for such finger pressure because the contact of the flat surfaces 96 and 56 and the magnetic force . between the magnetic prism as 83 and the embedded magnetically permeable steel wire as 51-54 then provides for a stable and firm location of such panel allowing it to be repeatedly used for such practice.
• the apparatus 38 also provides that pressing the edge 93 of the panel of a unit as 104 as in FIG. 9 tilts that tone index unit and automatically lifts the other end 94 of the panel above the surface 56 to a position at which it may be readily grasped between the player's fingers 97 and 98 to be thereafter readily positively displaced toward or away from the head 56 of the base 50 or reliably and easily removed from the array of tone index units on the base 50.
• the tone index unit panels are of such size as to be close to each other in arrays as in FIGS.5 and 11 to 18 in order to provide large enough letters to be readily visible to the student using apparatus 38 and also have such a size that they automatically are readily aligned relative to the stripes as 61, 62 and 63 to provide accurate guides to the finger positions on the simulated fingerboard 40 that are conveniently located and accurate representations of the position of the player's fingers on the simulated fingerboard needed for production of the desired notes on the true instrument 41.
• the unit tilts and indicates to the player the inaccuracy of the finger position applied. Thereafter, the unit as 103 and 104 returns to its position parallel to the surface 56 of the board 50 from which position such unit was tilted after being incorrectly struck. Such return is automatically effected due to the contact of the edge as 86 of the magnet and the wire as 52, which wire is at the surface of the board 56. Accordingly the note index units also serve as indicators of incorrect finger position and by so serv-ing assist the player in correct placement of finger position during finger position practice in a given key.
• Figure 19 shows the major keys in capital letters and the corresponding minor keys are shown in lower case letters.
• FIGS. 20-28 the only change for successive tonics that needs to be made in the finger positions, which positions are illustrated by FIGS. 5 and 11-18, is to move the tone index units so that there is only a one-half step between the third and fourth degree and only a one-half step between the seventh and eighth degree of each scale.
• the apparatus 38 thus provides for (1) illustratin those relationships of finger positions and notes in any one and all of a variety of scale as shown in FIGS. 5 and 11-18 and also to (2) readily (a) change the position of the tone index units on the simulated fingerboard and (b) to readily replace the tone index units to illustrate changes in their relations in a manner that is closely related visually and by tactile sense to the finger positions required for producing such variety of finger positions.

• Such lower prisms has such size, thickness, and location as to (a) provide that the unit resists displacement when the panel pressed at a position directly on top of the magnet and thus the unit serves as a practice element for proper finger positioning, and, also, (b) when the top of an edge of the panel is pressed downward toward the surface 56, as in FIG. 9, the unit tilts, as shown in FIG.
