Watch the Bossa Integrated Solo online guitar lesson by Mimi Fox from Flying Solo
Another thing that guitarists worry about is sounding "empty" and not filling up the "space". This is also a mistake. If you listen to my solo here you'll see that I start very simply and leave tons of room. This accomplishes two things: First it gives the listener a chance to relax into the groove without a lot of complicated ideas happening. Second, it lays a foundation for the more complex lines to follow. This results in a successful story being told. It develops naturally and spills out in a relaxed fashion.
