So now we're going to take a look at our A major scale and it's listed right here, even though it says A flat, that's a typo. So I can't have copyists do your work. So we have A major scale, and we start here on the fifth fret, five, seven, nine, five, seven, nine, six, seven. So five, seven, nine, five, seven, nine, six, seven. And you want to write this down at home, and the scale's written below it, A, B, C sharp D, E, F sharp, G sharp, A. And you know you are in the key of A major when you have three sharps. And that's how you know you are in A major. So you have five, seven, nine, five, seven, nine, six, seven. If we look at the fretboard, it falls really easy. Five, seven, nine, five, seven, nine, six, seven. And we only have to learn up to there because we're only applying chords on these three strings. So now we can go through and find any chord, and no matter what chord it is it's going to fall within these three strings between these two frets right there on the fretboard. There to there. So we're really boiling it down to this little section of the fretboard. But again, we could play all twelve notes there and we can apply different chords to any one of those notes.
