Here are the five basic forms of the Blues scale. These should be easy to learn because the only difference between the Blues scale and the minor pentatonic scale is the addition of one note, the b5. You simply add this note to the pentatonic scale forms you already know. Examples 349-352 provide some licks that use all these forms of the Blues scale in various keys. Learn each one and then transpose them to all twelve keys. For an in depth study of the Blues scale, see Progressive Complete Learn to Play Blues Guitar Manual.
