Description

Aug. 1931.

Filed July 2. 1928 Patented Au 18, 1931 'UMTED TA rmiivx xoamcx, or onroeeo, ILLnioj S, Assicnon or CHICAGO, rumors, A conronnrron or rumors TO. emit; MUSICAIi mum-E JELUCKEI) straine MUSICAL restateme- L Y Y 1 Application fi1edJ u1y.2, pThe objectiofthis invention is to provide aplucked string musical instrument of improved'tone qualit and in which the musical tones produce by the vibration of the strings are enriched and the resonance of i the instrument is enhanced by increasing the naturalharmonics or over-tones produced when the strings are vibrated. 7 Numerous other objects and advantages of athe invention will be apparent as it is better understood from the following description, ,which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof. I

Referring to the drawings: Figure 1 isa' perspective view of a plucked string musical instrument constructed pursuantto the invention; and I 1/ Fig 2 is a detailed plan view of the finger ;20 board, showing the improved combination 1 and arrangementof the strings.

I; The-plucked string instruments ShOWllxlIl ,the drawings may be termed, tor COIlVGIl1-' ence, a tenor.guitar, although it-may be played according to the tuning in a variety of other ways, for example, as abanjo, a ukelele', or a mandolin.

' The guitar 11 comprises a, hollow sound ;box: or body 12, in the belly 13 of which is 30 provided a sound hole 14 located underneath between the lower end of the the strings 15 and the bridge 16. Theneck .117 ofthe guitar extends from the top of the I sound box 12 to the scroll or head 18. The finger board 15 is mounted on top of the neck ;17-and eXtends-thereover from the base of the scroll 18 and over-the belly- ,ot'the instrument substantially to the sound hole 14. As shown, the scroll 18 is inclined backwardthe usual manner from the neck 17and top of the finger board 15. If desired, the

I fingeringot the instrument in playing may a .be assisted bya plurality of'frets 19 which 1 mark, the tone positions of difierent pitch on I 15 v the ifinger board.

-, The strings are secured at their'upper ends tothe tuning pins 20 which may be operated in the ordinary mannerby tuning pegs. 21.

\ From the tuning pins 20: the-strings are 5 strung over thefinger board 15 and bridge 16 1928. Serial no; 289,837;

mounted on the belly ofthe instrumentand are secured at their lower ends to the tail piece 28 which is mountedat the bottom of the body or sound box 12 and projects over the belly 13.

In a string instrument of the type shown in the drawings, the musical tones are produced plucking the strings either with the fingers or a plectrum to set the strings in vibration. The various intervals and tones of thescale'are attained in playing by the usual method of fingering the strings on the finger board 15..-

The illustrative instrument provides an improved combination of the strings which increases the natural harmonics of the fundamental-tones produced in playing and thus enriches andbeautifies the tone quality of the instrument. For convenience in illustrating thenovel string combination pro-- vided by the invention, the drawing shows an application thereof to an eight-string instrument of the plucked string type. vThese strings comprise the four principal strings 24, 25,26, 27 and four auxiliary strings 24, 25, 26" and 27. The principal strings are tuned in intervals of perfect fifthsand' comprise string 24 of pitch a; string 25 of pitch d; string-26 of pitch 9; and'string' 27 of pitch '0. The auxiliary strings are respectively mounted with, the principal strings so as to'constitute pairs of:

the strings are tuned in the following mannerzn Principal string 24 is a tenor banjo A string, tuned to-pitch a; auxiliary string 24 is a tenor banjo A string tuned to itch a; principal string 25 is atenor jo D= string tuned topitch d; aux-= strings with said principal strings, which iliary string 25 is a tenor banjo D string tuned to pitch (5; principal string 26 is a tenor banjo G string tuned to pitch 9; auxiliary string 26 is a tenor banjo A string tuned to pitch g; principal string 27 is a tenor banjo C string tuned to pitch 0; and auxiliary string 27 is a tenor banjo 1) string tuned to pitch a.

Principal strings 24c and 25 of the instrument are provided with auxiliary strings 2 t and 25. Because of the relatively higher pitch of the first and second strings, however, it may be preferable to employ for their auxiliary strings 2a and 25, strings of the same fundamental tone, as the principal strings 2i and 25, and to tune such auxiliary strings 2i and 25 so as to sound in unison with the first and second principal strings of the instrument. Thus the pairs of first and second strings 2424 and and 25-25 both sound the same fundamental tones a and (Z,.and the strings of each pair both produce harmonics in the same series. The use of pairs of strings tuned in unison in the higher strings of the instrument, however, doubles the volume of tone produced by these higher strings, thereby enriching and beautifying the tone quality.

The principal string '26, which may be tuned to the pitch g, may have its fundamental note and its harmonics produced by its own vibration enriched in like manner by its companion auxiliary string 26. For the auxiliary string 26 an A string may-be provided whose fundamental note corresponds in pitch with the first string 2i of the instrument. The auxiliary string 26 is raised in pitch one whole octave, however, so as to .sound the note g, or an octave above the fundamental tone 9 of principal string 26.

As both the principal and auxiliary strings 27 and 27 also sound, in addition to their fundamental notes, their own natural harmonics, according to the usual laws affecting the vibration of the strings, the fundamental note of the principal string 27 is enriched not only by its own natural harmonics, but also by the fundamenal note C in alto of the auxiliary string 27 together with the harmonics sounded by the auxiliary string. The harmonics of the auxiliary string are, for example, C in altissimo, its second harmonic, next, G in alt-issimo, the perfect fifth above and so on in the ascending series. It is evident that this combination of the two strings 27 and 27, which are sounded simultaneously, greatly enriches and beautifies the tones produced by the vibration of principal string 27.

It is thought that the invention and many of its attendant advantages will be understood fr-om the foregoing description, and

it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
