Watch the Soloing Study #1 online guitar lesson by Jon Finn from Modal Rock Soloing
After a brief explanation of how the chords of this section work, Jon demonstrates the C Lydian scale, then solos freely over it. Note that he demonstrates a simple fingering, then goes all over the neck. Once the sound of the scale is really in your head, it's much easier to figure out where the notes are all over the neck. To start with shapes can be a bit like letting the tail wag the dog. Get the sound in your head first.
