I, myself, used to play a lot with Harmonicas. Well, remember our post about HarmoNESca couple days ago?
Well, here’s some cool explanation on how Harmonicas are actually made and the workings.
The harmonica, or mouth organ, is a hand-held rectangular musical instrument. As the musician inhales and exhales into evenly spaced air channels, the metal reeds within produce musical tones. The length and thickness of the reed determines the note that is heard. Descended from the Jew’s harp and Chinese sheng of ancient times, the harmonica has engendered various nicknames, including blues harp, pocket piano and Mississippi saxophone. Since its beginnings in the early 1800s, the harmonica has been used in variety of musical forms, from classical to folk to country to rock to blues to jazz.
