Tuning
Main article: Guitar tuningA variety of different tunings are used. The most common by far, which one could call the "standard tuning" is:
- eI - b - g - d - A - E
The above order, is the tuning from the 1st string (highest-pitched string e'—spatially the bottom string in playing position) to the 6th string (lowest-pitched string E—spatially the upper string in playing position, and hence comfortable to pluck with the thumb.
| String | Sci. pitch | Helmholtz pitch | Interval from middle C | Semitones from A440 | Freq., if using an Equal temperament tuning (using ) |
|---|---|---|---|---|---|
| 1st (highest pitch) | E4 | e' | major third above | -5 | 329.63 Hz |
| 2nd | B3 | b | minor second below | -10 | 246.94 Hz |
| 3rd | G3 | g | perfect fourth below | -14 | 196.00 Hz |
| 4th | D3 | d | minor seventh below | -19 | 146.83 Hz |
| 5th | A2 | A | minor tenth below | -24 | 110 Hz |
| 6th (lowest pitch) | E2 | E | minor thirteenth below | -29 | 82.41 Hz |
This tuning is such that neighboring strings are at most 5 semitones apart. There are also a variety of commonly used alternate tunings.
