- Middle C is C4
- G above middle C is G4, and
- F below middle C is F3
In order for us to determine their locations, a few functional considerations of the guitar fret board construction need to be realized:
- First, the guitar has 6 strings that are tuned differently in open and 18-24 frets.
- Each fret advances the note placed before it by a semitone
Thus, a guitar has anywhere from 108 to 144 fret-string combination position, which means that many pitches. Again, the range of a standard tuned guitar is E2 to E6 (a total of four octaves i.e. 48 individual pitches / frequencies when the octaves are divided into the standard 12 notes ). Thus,
A particular pitch (frequency) can occur on more than one string. From the above, it is clear that a pitch must be playable in at least 3 different string-fret combination to make up the fabled 144.
This is true and the locations of the notes mentioned above on a standard 6 string, 24 fret guitar tuned to standard tuning are as follows:
|Middle C||F above C4||G below C4|
|S: 6; F:20||S: 6; F:11||S: 1; F: 3|
|S: 5; F:15||S: 5; F: 8||S: 2; F: 8|
|S: 4; F:10||S: 4; F: 3||S: 3; F:12|
|S: 3; F: 5||x||S: 4; F:17|
|S: 2; F: 1||x||S: 5; F:22|
N.B. S means "sting number" and F means "fret number." Calculations were done, taking S2;F:1 as middle C and going above and to the right to arrive at middle C every time, and similarly for the other two.
There is one thing different though - as one changes the strings, the timbre of the note (not the pitch /frequency) changes.
