Playing octaves on the chromatic can be difficult at first because the notes are four holes apart instead of three. This means you have to block three holes with your tongue instead of two. The following example is a demonstration of several pairs of octaves on the chromatic harmonica.
Practice the technique using exhale and inhale notes in one position before trying the whole exercise. It is difficult so be patient and practice it for a short time each day among your other exercises. Once you can do the basic exercise, try playing some scales in octaves as demonstrated in example 31.1.
The next step is to play some melodies in octaves as shown here. There are no breathing indications under the notes here, but you already know all the notes so this shouldn’t be a problem. If you have trouble, simply listen to the recording and imitate the sounds you hear.
This one is a Blues in third position in the key of D minor. It is similar to one you learnt earlier on the diatonic harp. All the positions are easier to play on the chromatic because there is no bending involved. Bending notes on the chromatic is not recommended as it can damage the harp!
