 Okay, so now we've done our first lesson on fretboard geography and we've named all of the natural notes going up the fretboard. We're now going to take the time to make sure we know the names of all the flats going up the fretboard. So it's essentially all the stuff we just did, but now we're going to fill in the gaps in between. So, this isn't really difficult. When we have a gap, let's say between G and A, that fret in between when we're thinking flats is A-flat, okay? So we have to sort of think ahead to that next letter name as we're moving up the fretboard. So from the E string we have an E, F. Now G is here, so this is G-flat. This is G, A is here, so this is A-flat, A, B-flat, B. Now remember, there's only one fret between B and C, so this is just still C, D-flat, D, E-flat, and E. I'm sure you all get the idea. And once you have that squared away, then we'll do our little exercise, and this really forces you to think moving up the neck, we'll get our drum beat going again, and just do that exercise. Let's go on the E. E, F, G-flat, G. Say it along with me, A-flat, A, B-flat, B. C, D-flat, D, E-flat, E, A, B-flat, B, C, D-flat, D, E-flat, E, F, E-flat, E, E-flat, G-flat, G, A-flat, A, D, E-flat, E, F, G-flat, G, A-flat, A, B-flat, B, here's C, C, D, D-flat, D, G, A-flat, A, B-flat, D-flat, D, E-flat, F, G-flat. You want to get to the point where you really know the names of every single fret on the fretboard on all four strings. You get to the point as a bass player where this really starts feeling a bit like a graph with lines going this way and lines going this way and the longer we go through the lessons the more we're really going to talk about those relationships. So know those note names and it will make everything a lot easier. Give that a try. Make sure you've mastered all the flats on the bass fretboard.
