Watch the Improvising over a Jam Track Using 3 Shapes Overview online guitar lesson by Rob Garland from Melodic Soloing: Major Scale

Here I'm improvising over a rock ballad jam combining major scale Shapes 2, 3, and 5 in the key of E major. The chords for the jam are:
|E6 |C#m7 |F#m9 |B7 |

The tempo is 90 BPM. Move between the shapes in a linear fashion as well as ascending and descending through the scale. Make sure you're aware of melodic elements such as bends and slides to connect the shapes.
