Harmonica structure
The harmonica is a wind and pocket instrument that consists of three main parts: a piece called the mouthpiece, a blade called a slide, and strips called wind saver valves. The tapes vibrate when the wind is blown through the mouth of the instrument. These straps are attached to the body at one end and are free at the other. The sound of the harmonica is very similar to other instruments of its family such as Melodica, Concertina, and Accordion. The similarity in the structures and the way the sound is produced has led to this similarity. The mouthpieces are divided into several groups based on their capabilities and the sound they produce, the most important of which are: • Thermo and octave oral instruments for folk and pop styles • Diatonic mouth instrument for folk, Irish, country, blues, and pop styles • Chromatic mouth instrument for Irish, jazz, classical, and pop styles • Bass and chord oral instrument for classical and pop styles The most famous oral musicians are Steve Wonder, Little Walter, Tutt Tillmans, John Popper, Bob Delaney, etc.
