There are three types of harmonica, although there is more harmonica with more changed characteristics. We should base the correct choice of the required harmonica on the musical style. One will play and the effect one will put in. There are 3 basic types: diatonic harmonica, tremolo harmonica, and chromatic harmonica.
Overtone harmonics: This is the first harmonica created. Although they are most used to play blues. They can play a variety of popular music with a diatonic harmonica.
The diatonic harmonica has 10 holes, allowing the player to use a tone and semitone. Equivalent to the white notes on the piano (take the C major as an example). However, other notes can play using folding and over winding techniques.
Tremolo harmony: This harmonica suitable for playing traditional music because it can produce wonderful “tremolo” effects. Popular between the Gospel and the Old World. Folk, country, Scottish and Irish music.
The tremolo harmonics comprise two vertical holes placed. Each contains two reeds, one de-tuned to the other. When they vibrate together, these reeds produce a unique tremolo effect.
Sub-harmonics: Achromatic harmonica has compensated for missing notes in the dichromatic harmonica. You can play tonal and semitones with the help of a key swipe. (a semitone refers to the semitone when playing white and black notes; C, Db, D, Eb, E, etc.).
Some other harmonic types are:
Octave tuning: Octave tuning is like the Tremolo model in terms of cane design and musical range. However, instead of tuning the reeds to the same note. Each reed with two holes tuned an octave apart from each other.
Tuned diatonic scale: It is used to enjoy the advantages of other notes and scales. Not present in the chromatic harmonica.
Chords and metal harmonica: These are two or more harmonics used for ensemble performance.
There are thousands of different models on the market, diatonic or chromatic harmonica, and different models of different harmonics. We can make harmonics of metal or plastic.
