The term 'Fretboard Locale' refers to the NECK of a guitar or other stringed instrument. The NECK is the part of the instrument that holds the strings and frets, which are the raised metal bars that divide the NECK into sections. The fretboard is the flat surface on the NECK where the strings are pressed down to create different notes. The NECK is an integral part of the instrument, as it is the part that allows the musician to play different notes and chords.
