I have not been playing for long at all and Im trying to self teach myself. I figured out on my own that the strings are supposed to face away from the body....so I'm off to a good start. Sorry for my ignorance but.....I'm not 100%....well...probably not even 2% sure on what exactly the number beside a not stand for. For example D7. I know what a D note is. But the number throws me. And for more than just the bloody D note. Can someone explain it...in laymens terms.
