Learn the major scale and learn it well.
Play it in many variations over various chords.
For example, in the key of A, use the A major scale starting on string 3, fret 2.
G string 2 - 4 (A B)
B string 2 - 3 - 5 (C# D E)
E string 2 - 4 - 5 (F# G# A)
play this over the A chord
Alternately, change to A mixolydian, by changing the above to
G string 2 - 4 (A B)
B string 2 - 3 - 5 (C# D E)
E string 2 - 3 - 5 (F# G A)
Notice that only the G# note on the E string has been changed, to G. This is known as the flatted 7th of the A scale. You are now actually playing all the notes of the D major scale. Since you start on A, it is called A mixolydian.
In a typical A - D - E progression, the mixolydian should work nicely.
In songs where the major 7th chord is used, stick with the major (example, Eyes of the World, with its famous Emaj7). E major scale is a great way to move around on the E major parts in that song.
As for playing over the chords, you will soon see the chord shape under your scales, and can strum them freely in between notes of the scale, or in a broken fashion, i.e. the arpeggios.
The arpeggios are scale tones 1,3,5 in the key, starting from the various notes of the A major scale.
In A major, for example, the arpeggios are
A C# E (A major)
B D F# (B minor)
C# E G# (C# minor)
D F# A (D major)
E G B (E major)
F# A C# (F# minor)
G# B D (G# diminished, dim because the 5 is D, not D#)
I hope this helps, and if I goof, just post and I'll fix it.
