Choose from tools from well-known companies – Suzuki (Japan), Hohner (Germany), Seydel (Germany). These are the largest manufacturers of labial harmonica, which produce not only high-end harmonica, but also good instruments for beginners. Already for 800-1000 rubles you can buy an instrument on which it will be nice and convenient to play a beginner. Cheaper harmonics by unknown Chinese manufacturers are just pieces of plastic, not musical instruments.
Decide on the type of lip harmonica. Although there are many varieties of harmonics, most of them are used only by professional musicians who play in orchestras. For an amateur, the choice is significantly narrowed: it is only necessary to decide which, diatonic or chromatic, harmonica you need.
The most common variant is the 10-hole diatonic labial harmonica, it has only pure notes, that is missing semitones, but also they can be played if you master the special techniques of the game. Diatonic labial harmonica is the best choice for beginners, it is perfect for blues. On chromatic labial harmonica you can play all the notes of the sound without using special techniques, on such harmonica you can play classical works fully.
Harmonica tongues can be made of copper or of steel. Copper tongues are most common, they give an excellent sound but often break, especially in beginners who may overdo it in blowing sounds. Seydel offers harmonics with steel tongues, they are almost impossible to break.
Diatonic labial harmonics have different tonality. Beginner should stop at the instrument in “before major”, since it is for harmonics of this tone that most self-teachers are written, instructional videos are also usually recorded using such a harmonies.
Be sure to check the labial harmonica in the store, all holes should be well blown both on breath and on exhalation, the sound should be clean, without ringing and noises.
