The stringed musical instrument comprises a body having a string-slider nut assembly; a neck having a rectangular slot; a T-bar assembly having a plurality of holes fastened securely in the rectangular slot of the neck of the instrument; a finger board consisting of a plurality of rectangular pieces forming a plurality of lengthwise spaced recesses when the rectangular pieces are placed adjacent to each other, wherein the fingerboard is placed upon the T-bar assembly, and tubular barrel frets are secured firmly in the lengthwise space recesses formed in the fingerboard with barrel fret screws. The string-slider nut assembly includes a number of pulleys, through which a given string passes so that the string can be stretched to produce a high pitch and a "sliding" musical tone, as may be desired.
