This is a textbook for advanced players of the diatonic harmonica that includes 5-hole and chromatic playing techniques.
It also includes explanations on key changes and how to use minor harmonicas.
First, following the intermediate level, you will practice bass playing (simultaneous bass, large and small bass), and then you will learn the ``5-holes playing'' technique.
The next technique, "chromatic playing," is used when playing songs that contain semitones (sharp and flat) that cannot be produced on a single diatonic harmonica.
Once you have mastered the chromatic playing practice pieces using "tuplets," you can move on to learning about key changes and the minor harmonica.
