Here are two licks which use the C Blues scale. Like the minor pentatonic, the Blues scale can be used against minor key progressions, Blues progressions and major key Rock progressions. Try using rt against the jam along progressions at the end of the book.
Although the Blues scale originated in Blues, it has been used in many styles including Rock, Metal, Funk, Hip-Hop and Jazz. Listen to the sound produced by the addition of the flattened 5th degree in this example.
