How to Play the Harmonica
There are various methods of playing, depending on the type
Set the instrument in front of your mouth and move the instrument left and right
When playing the harmonica, take the instrument in your hand, set in front of your mouth, and then blow and draw through the mouthpiece while moving the instrument left and right, vibrating the reeds and producing notes.
How to play chords
With any harmonica, you can produce a note that you want to play by setting the hole for the note in front of your mouth and playing. Chords are played similarly: Typically, you bring all holes required for the chord in front of your mouth and close off the holes that are not needed with your tongue. When you want to insert accompanying notes into the chord, play with your tongue removed from the holes for those notes.
Incidentally, harmonica performances with chords are typically played with double-reed harmonicas or 10-hole harmonicas.
One single harmonica which provided twice enjoyment
Yamaha built for some time a fairly special harmonica named the Melo Chord, which offered twice the enjoyment from one single instrument. It was constructed with a mouthpiece on either side, one of which was for a single-reed C, D, E, F, G, A, B, C harmonica, whose counterpart was that of a chord harmonica that could easily produce five chords including C-E-F, F-A-C and G-B-D. The central portion was partitioned at an angle, and breath came out of holes in the center. When both sides were played, ensemble was produced with one single instrument because of the way in which it was devised.
The chord harmonica side also provided unique performances. In groups of three holes each, the leftmost was the low note. Thus, if the player started by blowing into the left hole and then moved on to blowing into all three holes, he or she could create a thud-cha-cha-cha rhythm.
* Yamaha has now discontinued production of harmonicas.

Various ways of performing
The harmonica can produce notes reminiscent of a brass instrument or the accordion. This section will explain various methods of playing that produce notes that one would not think were played on a harmonica.
Hand vibrato method
This expressive method adds emotion to the notes played by shaking the instrument with the palm of the hand.
Just the top row of a double-reed harmonica is used to play, producing tones that sound like a violin.
A method by which a melody can be played while beating a rhythm. All by yourself, play the melody toward your right cheek, while, from the left, strike the mouthpiece with your tongue to block the holes of notes you do not want to sound. Leave the tongue there moving, striking the front of the mouthpiece, and creating a rhythm as you play.
Playing chromatic-scale notes on non-chromatic double-reed harmonicas
A feature of the chromatic harmonica is that it is able to play chromatic-scale notes, but these can also be played on regular double-reed harmonicas. In this case, two instruments are played, one playing the notes that would be the white keys on a piano, and the other playing the notes for the black keys.
While playing, the harmonicas are raised and lowered, as necessary, with the harmonica being played placed in front and the harmonica not being played lowered toward the back. The mouthpieces become narrower on the oblique. Therefore, four holes are stuck together, which is supposed to be easier to play once one is used to it.
Playing with the left and right sides reversed
The layout of the notes is such that the lower notes are lined up to the left and the higher notes to the right, but the instrument can also be played turned upside down. Holding the instrument so that the notes get higher the farther to the left you go might be a good mental exercise.
