I was looking at a tab on how to play Alivn Lee's I'm going home
and it said that he uses pentatonic and blues scales

but isn't a blues scale basically a modified pentatonic scale? so why wouldn't
they just say he plays blues scales which is all the notes he uses anyway?

also: can a pentatonic scale include any notes just as long as their is five
in the scale?

this has been burning in my head for about a week now
and i figured this would be the place to find the answer
cause wikipedia's explination of a pentatonic scale was a little weak.
