I'm wondering what something is called,
it is a diagram of the different notes of a key, i think, it looks kinda like this:
E | |---|---|---|-o-|---|-o-|-o-|---|---|---|
B | |---|---|---|-o-|---|-o-|-o-|---|---|---|
G | |---|---|-o-|-o-|---|-o-|---|---|---|---|
D | |---|---|-o-|-o-|---|-o-|---|---|---|---|
A | |---|-o-|---|-o-|---|-o-|---|---|---|---|
E | |---|-o-|---|-o-|---|-o-|-o-|---|---|---|
except the circles are filled in, i can't remember what they are called, any help is appreciated.
