Or how to navigate between guitar frets.
I often envy the pianists for the clarity of the keyboard. They also have the full spectrum spread right in front of them and may not even be forced to turn their heads so much.
Therefore, do not hesitate, and to understand the sequence of tones, let's first learn the keyboard.
The guitar finger is, at least in terms of clarity, a little more complicated. This is mainly due to intervals between strings. They are irregular due to the anomaly between the second and third strings (in standard tuning).
Each playing field on the fingerboard represents a halftone in terms of distance. While the tones are taller or lower in the keyboard, they are distinguished by dark keys, but the guitar finger does not make a distinctive distinction between these tones.
