Lesson 1: The m7b5 Arpeggio...
Breaking out of the pentatonic boxes doesn’t mean that you have to totally change the way you play guitar and start all over again, in fact, it’s very much the opposite! It simply means that you use your pentatonic knowledge as the foundation to build a more varied library of ideas.
In this lesson we will be taking the C#m7b5 arpeggio (a half diminished arpeggio) and add it to the pentatonic box 2. We’ll get into the theory in a minute, first of all, let’s learn the shape:
Our second task is to layer this new shape on top of the B minor pentatonic shape 2. Theory aside for the moment, this layering effect will allow us to quickly call upon the m7b5 arpeggio without having to think too hard about it! The little exercise we looked at in the video is as follows:
So, for those of you who like to know what’s going on behind the scenes, let’s talk about the theory behind this concept. We are using the key of B minor for now. If you are a pentatonic player you probably know that if someone shouts B minor, you pop your first shape of the pentatonic on the fretboard on the 7th fret and away you go! Well, thew other thing that happens when the key is called is that you can harmonise the B minor scale to create a series of 7 chord shapes. These are <em>B minor, C#m7b5, D major, E minor, F# minor, G major, A major and finally back to B minor</em>. Each one of these chords uses only the notes from B minor to create the chord, and therefore they work perfectly together in key.
All we are doing is taking one of these chords (we could take any), in this case the C#m7b5, and playing through it over the B minor backing track. We know every note will work as the notes are built from the B minor scale. The cool effect you get is that of a bit of tension, as these notes spell out a chord that may not be playing underneath (unless you beautifully land it on the correct chord). This could be a bit dodgy sounding if you just keep going up and down it, but used conservatively and resolving to the pentatonics after each lick, provides a cool sound that adds a bit more spice to your playing and gets you out of those pentatonic boxes, even just for a moment!
