Guitar It is flat on classical guitars and slightly curved crosswise on acoustic and electric guitars. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Most modern guitars feature a 12" neck radius, while older guitars from the 1960s and 1970s usually feature a 6-8" neck radius. Pinching a string against a fret on fretboard effectively shortens the vibrating length of the string, producing a higher pitch. Fretboards are most commonly
Standard tuning and drop down to lower open string notes. This is also more practical for the whole playing range of E–C♯ (on a 21-fret guitar), as it can fit easily into the treble clef when written as E–C♯. Transposing by an octave may be explicitly indicated by a suboctave clef, where a treble clef has an '8' placed below it, or a normal treble clef may be used for simplicity. Other plucked string instruments and their respective standard tunings include: Standard tuning In music, standard tuning refers to the typical tuning of a string instrument. This notion is contrary to that
