Take this backing track[0] and try using the A pentatonic minor scale or A blues scale from this website and practice soloing using the marked notes. Try staying "in the box" which are the highlighted areas where you don't have to move your hand a lot to play all the notes of the scale.

Here's an example of someone mostly staying "in the box[1]." Is that even the right term?
