Help with the notes

[AccordionNewbee]

Good News Everyone,my Sofia Mari is back! They fixed her up and she plays better than ever! So im starting my training all over again. I read this on youre tabbs section. Are tabbs the notes of a song?

heres Duelo acostumbrandome:

G811, C811, F710 X 2, C811, G811 X 2 (HOLD),
G811, C811, F710 X 2, C912, C811, F710 (HOLD)
G811, C811, F710 X 2, C811, G811 X 2 (HOLD),
G811, C811, F710 X 2, C912, C811, F710 (HOLD)

whats G811? i know theres a g-row but whats the number for?

also i was confused by this:

Acostumbrandome
Grupo Duelo
GCF (SOL) Accordion
Scale of C (DO)
Tabbed By: Soldado12

Sol?Scale of C? i know theres different scales but is the whole song in this scale?

I know i sound dumb but im a newbee. Any help would be appreaciated.

G811 is on a 34 button accordion, you dont have one so you gotta play going in. The numbers are the buttons on the row, like G23 is row G buttons 2 and 3. C scale is all one scale.

Anytime you play a song its in one key. There are times where you can play in C and convert over to G or what ever key you want.
