Now let us look at some substitution options for soloing over dominant chords.
Instead of using a C Mixolydian scale, another possibility for a C dominant chord would be the Lydian dominant scale. This is the 4th mode of G melodic minor. This scale is shown below with the degrees as they relate to a C13 chord. Notice the sharpened 11th degree created by using this scale.
The #11 creates two different arpeggios from the Mixolydian scale. These arpeggios all work over a C dominant chord regardless of whether the #11 appears in the chord chart or not. It all depends on the musical context.
Now try this line which is derived from the C Lydian dominant scale. Listen to the CD and notice the slightly 'outside' sound created by the #11 degree. Learn this line, transpose it to all twelve keys, and then create your own lines from the same scale.
