What are the octives of the strings?

What are the octaves of the strings on the guitar?

in standered tuning the string are
e (high)
B
G
D
A
E (low)

But what are the numbered octaves of the notes?

I know on piano the mid C is in the 3rd Octave, so C3. Is the low E and E2?

I don't think guitar has numbered octaves.
If it does the low E would be the first.

I've never heard of this...

not sure on Piano but it would be best to sit with a guitar and find the same pitch E on Piano, then you would have your answer.

this is a quick one so I'll answer



octaves are numbered by the reference A=440 (or if you use a different one). All octaves are numbered by that, thus regardless of the instrument if your tuned in 12-tone equal temperate the octaves are numbered.



middle C is C4

OPEN STRINGS
E---E2
A---A2
D---D3
G---G3
B---B3
e---E4

middle C shows up fives times on the guitar and is in about 25 positions (can't remember exact).

C4 is the start of the treble register, thus in open position your mostly in bass. The D string don't get out until 10th fret.

Octaves are confusing on the guitar, but if you want to become a competent guitarist it is something your going to need to learn. Or have the ears of God and don't need music theory at all. As you need it one to read notation, and all forms of arrangement.

Now I know what you're talking about.
