What is a harmonica?

Harmonica a free reed wind instrument. It produces tones or notes when you blow air into or draw air out by placing lips over individual holes (reed chambers) or multiple holes. The wind pressure caused by blowing or drawing air into the reed chambers causes a reed or multiple reeds to vibrate up and down thus creating sound.

A harmonica contains many chambers. Each chamber has multiple, variable-tuned brass, bronze, or stainless steel reeds. The reeds are riveted at one end and loose on the other end. The loose end vibrates and creates sound.

Reeds are pre-tuned to individual tones. Each tone is determined according to the size of reed.

Longer reeds make deep, low sounds and short reeds make higher-pitched sounds. On certain types of harmonica the pre-tuned reed can be changed to another note by blowing or drawing air strongly into the chamber. This technique is called bending.

There are many types of harmonicas; Diatonic, Chromatic, Tremolo, Orchestral, Bass, each used for its own specific sound and can be played in many keys and many types of music.

You may use a harmonica to play blues, Malay joget, American folk music, jazz, classical music, country music, rock and roll, and pop music. The harmonica is also finding its place in more electronically generated music, such as dance and hip-hop, as well as funk and acid jazz.

The harmonica has other nicknames, especially in blues music, including: harp, blues harp, mouth organ (widely used in India), blues mouth organ, and bangsi (in Malay language).
