Abstract
Abstract A new musical eight-string instrument in which the body, or resonance chamber, has an ovoidal lute-like shell and a flat sound board having an oval-shape contour, with a larger arc on the bass string side of the neck and a smaller arc followed by a concave portion on the other side of the neck. The larger side meets with the neck at the twelfth fret, while the smaller side meets the neck at the twentieth fret to allow easy access to the strings at all frets. The neck of instrument is joined to the shell by a spine. This new instrument is also tuned in a new manner, so that its eighth open strings are tuned in seven superimposed intervals of four half-tones, in order to make it much easier for the finger board fingers of the player. A positive note identification means is also disclosed for the finger board of any string musical instrument, consisting of rectangular areas of visually contrasting shades, one shade for the natural notes and another shade for the altered notes.
