Standard tuning strings. This is done to simplify fingering. A few guitarists, mostly those using tapping, play without this interval, instead tuning in all fourths; thus on a six-string guitar the top two strings become C and F instead of B and E. Other unusual tunings include all major thirds, all minor thirds, and various other choices. In standard notation, the guitar sounds one octave lower than it is written. This is to avoid switching between treble and bass clef, or using ledger lines or 8vb, since it is very common to play past the 12th fret on the E string (E)
Zero fret fret 1 to 3 mainly) the elevated fret keeps the string action higher and helps to avoid string buzz. The term "guitar intonation" denotes to what precision the ideal equally tempered musical scale can be produced by a guitar, while "piano intonation" refers to the setup procedure of the individual hammers in the piano keyboard. A conventional nut or an elevated zero fret will cause pitch errors on the lower frets due to the increased pressure on the strings. The fret distances would have to be corrected for that increased tension effect, but with guitars that is not common. On
