Piano teaching aid
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     Piano Teaching Aid. 
     2. Description of the Prior Art 
     In the teaching of piano, one of the major obstacles for a beginning student is to visually associate a note on either the treble or bass lines of a sheet of music with the correct key on a piano keyboard, as well as to remember which white keys on the piano keyboard are to be sharped or flatted. Various devices have been proposed and used in the past to assist the student in overcoming the above mentioned obstacle. However, in the main such prior art piano teaching aids have been unduly complicated, are difficult to use and understand, and as a result have been of limited assistance to a beginning student. 
     A major object of the present invention is to provide a piano teaching aid that is simple and easy to use, is inexpensive, and one that will facilitate the student in acquiring the ability to sight read music. 
     SUMMARY OF THE INVENTION 
     First, second and third overlay segments that are initially removably secured to a backing strip on which a replica of the white and black keys of a piano keyboard are defined. The overlay segments are subsequently removed from the backing strip and removably secured to the white keys of a piano keyboard. The first overlay segments when so mounted on the white keys define a treble signature, and from which signature elongate tabs project to indicate to the user that the keys on which the tabs are mounted correspond to notes on the lines in the upper group of the latter on sheet music. 
     The second overlay segments when removably mounted on white keys of a piano keyboard define a bass signature from which elongate tabs project. The white keys identified by the elongate tabs indicate to a user that these keys correspond to notes on lines in the bass of the sheet music. The third overlay segment is removably mounted on middle C key of the piano keyboard, which corresponds to a note on the line between the treble and bass of sheet music. Notes in spaces between the lines in sheet music are easily identified by a user on a piano keyboard, by the user referring to the two tabs on the piano keyboard that are on opposite sides of the white keys. If desired, fourth overlay segments may be provided that are affixed to white keys on the piano keyboard above and below the treble and bass to indicate to a user the position of additional notes on the music. Fifth overlay segments in the form of sharps and flats are provided that may be removably secured to appropriate white keys on the piano keyboard to remind a user that these keys must be sharpened or flatted. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     FIG. 1 is a perspective view of a conventional piano keyboard with the invention removably mounted thereon, and phantom lines illustrating how the invention visually identifies the keys on the keyboard identified with notes on the treble and bass lines of a sheet of music; 
     FIG. 2 is a top plan view of the invention removably mounted on a backing strip; 
     FIG. 3 is a top plan view of the backing strip with the overlay segments being removed therefrom; 
     FIG. 3a is a top plan view of a piano keyboard with the overlay segments being sequentially applied thereto; and 
     FIG. 4 is a perspective view of a typical overlay segment. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention includes an elongate backing strip H best seen in FIG. 3 that has a replica J of a portion of a conventional piano keyboard defined thereon. In the drawing the replica J is illustrated as including the octaves above and below middle C and portions of the octaves adjacent the upper and lower octaves. 
     A number of first overlay segments K are provided that are formed from a pliable sheet material that have first and second oppositely disposed surfaces 30 and 32. The first surfaces 30 are coated with a film of pressure sensitive adhesive 34 as shown in FIG. 4 and the second surfaces are of a color that contrasts to the black and white color of a piano keyboard. 
     The first overlay segments K are removably disposed on the replica J and define a treble signature thereon as shown in FIG. 2. A conventional key board L is shown in FIG. 1 that has a sheet of music M disposed adjacent thereto, which sheet has treble lines N, bass lines O and middle C line P, and notes Q on these lines, imprinted thereon. 
     The first overlay segments K are adhered to the white keys of the keyboard L as shown in FIG. 1 to correspond to the treble lines N, with the overlay segments on keys e, f, g, b, and d having forwardly extending tabs K-1 included as a part thereof that visually indicate to a user that the keys on which they are mounted correspond to the treble lines N. Thus, when a user sees a note Q on a line of the group of treble lines N he immediately relates it to the keys of the keyboard L on which the overlay segments K are mounted. The tabs K-1 identify the keys of the keyboard L with corresponding treble lines N and the user when he sees a note Q on a treble line N knows which key to strike. 
     When a note Q is in a space between two treble lines N on the sheet of music M, the user knows immediately that the key to strike on keyboard L is situated between two of the tabs K-1. 
     A second group of overlay segments R with tabs R-1 is provided, that is of the same structure as the first group K, but in the form of a bass signature that is applied to the white keys of the keyboard L as shown in FIG. 1. The overlay segments R serve the same function in identifying keys in the first octave below middle C on the keyboard L, as the first overlay segments K do on keys in the first octave above middle C. 
     Third, fourth and fifth groups of tabs S, T and U are provided that are removably secured to the middle C key of keyboard L, keys corresponding to lines of the treble above the group N, and keys corresponding to lines of the bass below the group O on music M. 
     In FIG. 3 a hand 2 is shown sequentially removing the overlay segments K, R, S, T and U from the backing strip H and in FIG. 3a a portion of the overlay segments is shown being applied to the keyboard L. The phantom lines in FIG. 1 illustrate the relationship between the sheet of music M and the invention when mounted on the keyboard L. Overlay segments V and W in the form of sharps and flats may be removably mounted on backing strip H and removed therefrom and applied to appropriate keys of keyboard L to remind a user that these keys must be sharped or flatted. 
     The use and operation of the invention has been explained previously in detail and need not be repeated.
