If you want to know how to play the harmonica, you must know that this wind instrument is available in different versions. The basic rules for playing the harmonica are the same for all kinds: they have to blow air into the individual holes or reed chambers to create sound.
However, the similarities end here when the pitches for different types of harmonicas are pre-tuned according to the pitch and tone they are intended to produce. For example, a ChengGong harmonica is different from any other because it has a sliding mouthpiece and a main body. Gong Harmonica was named after a wordplay with the surname of its inventor Cheng Xuexue. As already mentioned, this type of harmonica is supplied with a body and a sliding mouthpiece. The body consists of an 24-hole diatonic harmonica, which includes three octaves and starts from b2 to d6. The 11 mouthpiece of this type of harmonica can slide on the front of the instrument.
This feature generates a variety of chord selections and voicings such as seven triads, seven 7. Chords, three 6. Chords and seven 9. Chords. Gong Harmonica can also play melodies with one note and double stops over three diatonic octaves. Unlike other types of harmonicas, blowing and removing air from the instrument can produce the same notes. This is because voicing this harmonica is more like the note layout of an Asian tremolo harmonica. When buying a harmonica of any kind, you must pay attention to some points. For starters, you will want to choose a harmonica whose top plate feels good in the mouth and the holes are accessible for easier tongue blocking. Look for a model that lets you blow from the sides of the mouth as you reach the holes with your tongue.
