the preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed . it is chosen and described to best explain the invention so that others , skilled in the art to which the invention pertains , might utilize its teachings . referring now to the drawings in greater detail , fig1 shows the prior art construction of a pedal harp . traditionally prior art pedal harps 1 are made with laminated wood pieces forming the pillar 2 , the neck 3 , various parts of the body 4 , including the soundboard 5 and bridge 6 , and ii the pedal box 7 . each of the sections is joined together using adhesives and epoxies to make the harp frame . a faceplate 8 is attached to the neck 3 , and the strings 9 are connected between the faceplate 8 and soundboard 5 . a pedal harp 1 has a mechanism ( not shown ) which connects the pedals ( not shown ) to a series of discs ( not shown ) that , when engaged , vary the vibrating length of the strings 9 . this serves to change the key signature of the harp . the mechanism itself is attached to the underside of the neck 3 of the harp , and consists of a stacked series of linkages ( not shown ) which control the discs . the mechanism is controlled by a series of rods ( not shown ) which are located in a hidden passage 10 inside the pillar 2 . the lower ends of the rods are connected to the pedals in the pedal box 7 , and the upper ends connect to and control the mechanism and linkages . in traditional construction the rods are positioned inside the pillar before the neck is joined to the pillar . fig2 shows the pieces of the improved pedal harp 21 of the instant invention . the upper harp frame 22 , consisting of the pillar 23 and the neck 24 , is made as a single piece out of a carbon fiber material . the pillar 23 is hollow to allow the passage of the rods ( not shown ) from the lower end of the pillar 23 to the neck 24 . the faceplates 25 , which support the works of the mechanism , are connected to the upper harp frame 22 . the faceplates 25 are made of a carbon fiber material . a lower harp frame 26 , consisting of the body 27 , receiver 28 and sound board 29 , is made as a single piece out of the same carbon fiber material as the upper harp frame 22 . harp strings 30 are mounted in a conventional manner between the tuning pins ( not shown ) on the upper harp frame 22 and the lower harp frame 26 . the upper end of the lower harp frame 26 is attached to the upper end of the upper harp frame 22 by means of a broad tenon 31 on the top of the lower harp frame 26 , fitting into a receiver 32 in the upper harp frame 22 . the lower end of the upper harp frame 22 has a large extension , or tenon 33 , which is attached to a receiver 28 at the lower end of the lower harp frame 26 . the receiver 28 has a large opening ( not shown ) to allow the rods to pass through , as does the tenon 33 . the tension of the strings 30 , about 3000 psi , hold the upper harp frame 22 and the lower harp frame 26 together without the need of any adhesives or mechanical fasteners . the combined assembly of the upper harp frame 22 and the lower harp frame 26 are mounted on a pedal box 34 . the pedal box 34 is made of the same carbon fiber material as the other components . the pedal box 34 is provided with openings 35 through which pedals ( not shown ) are mounted . the pedals are connected to the mechanism by the rods ( not shown ) which extend via openings in the pedal box 33 , the receiver 28 and the tenon 31 up through the hollow pillar 23 into the neck 24 where it is connected to the mechanism . the mechanism , consisting of the faceplates 25 and the mechanism itself ( not shown ) is of conventional design but is connected to the neck 24 in a new manner with a recess receiver area 36 in the neck 24 into which the faceplates 25 of the mechanism are attached . fig3 is a view along the cross section a - a of fig2 . the neck 24 is hollow . the lower edges of the neck 24 are provided with recesses 36 in which the faceplates 25 are mounted so that the outside surfaces of the faceplates 25 and neck 24 are flush . bolts 37 fasten the faceplates 25 to the neck 24 using threaded tubes 38 . the bolts 37 may be countersunk if so desired . the mechanism extends through the faceplates 25 to connect to the strings 30 . although the carbon fiber pedal harp and the method of using the same according to the present invention has been described in the foregoing specification with considerable details , it is to be understood that modifications may be made to the invention which do not exceed the scope of the appended claims and modified forms of the present invention done by others skilled in the art to which the invention pertains will be considered infringements of this invention when those modified forms fall within the claimed scope of this invention .
