a plurality of strings that extend in a longitudinal direction and are tensioned; and
a fretboard underneath the plurality of strings comprising an elongate unitary body having unitarily constructed thereon a plurality of ridges extending transverse to the longitudinal direction and arranged in succession in the longitudinal direction to define separate frets, each ridge associated with a plurality of notes corresponding to the plurality of strings and being composed of a plurality of ridge segments, each ridge segment corresponding to a string of the plurality of strings, the plurality of ridge segments disposed adjacent to each other and each ridge segment being shaped relative to adjacent ridge segments to provide a desired intonation of a corresponding string as said string is depressed onto said ridge segment and plucked, to improve musicality of the instrument, wherein a first ridge segment of a ridge of the plurality of ridges is shaped to extend away from a second ridge segment of the ridge in the longitudinal direction to correct a frequency associated with a string extending above the first ridge segment to match a predetermined frequency.
