There is an mmorpg (game) where playing a guitar is possible, i want to know if this guitar scale or type relates anything to guitars in the real world
here's how C1 sounds : http://picosong.com/ESVu/
It's just 3 octaves of the chromatic scale. Based on what you say it sounds like it is not the scale, but the range given to compose in. The game is just giving you the range from C1 to B3 to play with to create / make music.
I don't really understand the connection between the chart picture and the sound file, but the sequence...
C, C#, D, D#, E, F, F#, G, G#, A, A#, B
... is the chromatic scale.
The numbers next to the letters look to me to be "scientific pitch notation" https://en.wikipedia.org/wiki/Scientific_pitch_notation
