I am learning scientific pitch in order to understand the guitar fretboard better, in terms of absolute pitch.
What I was taught, was that A to G, and then back to A up an octave.
When I look at the scientific pitch of the strings, I get this:
E2 A2 D3 G3 B3 E4
At first glance, it makes sense. But wait, B is above G?
The last three strings then become:
open, 1, 2, 3, 4, 5 (fret) G3, G#3, A4, A#4, B4, C4 B3, C3, C#3, D3, D#3, E3 E4, F4, F#4, G4, G#4, A5
This blows my brain, so on the fifth fret moving up you get
C4 E3 A5
How does this make logical sense? It goes down an octave yet higher in pitch?
Okay, now I realise like on piano that middle C is C4, and that is an easy reference (being roughly in middle, is the tonic of a scale that involves white keys etc. etc.) but is it really the first note in an octave in scientific pitch despite making sense only on a piano? Should I abandon scientific pitch for guitar and use 'real' octave (whatever that is!?)
In my computer programmer mind-set, where an index might start at 0 instead of 1 (okay, can get used to that), this is like an index starting at 3 and going up from there.
