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.
Music in Chicago
Chicago, Illinois is the mainstay of music in the Midwestern United States, where distinctive forms of the blues style (responsible for creating rock and roll) and house music, a genre of electronic dance music, have developed. The "great migration" of poor black workers from the south to industrial cities brought traditional jazz and blues music to the city, resulting in the Chicago-style blues and Chicago-style Dixieland jazz. Prominent blues artists included Hollyn Walf, Jr. Wells, Maddie Waters, Sonny Boy Williams, and more. The greats of jazz include Net King King, Jane Ammons, Benny Goodman, and Bad Freeman. Chicago is also known for its soul music. In the early 1930s, religious music was introduced in Chicago due to the contributions of Thomas A. Dorsey and became popular in the Pilgrim Baptist Church. In the 1980s and 1990s, heavy rock, punk, and hip hop also became popular in Chicago. The Chicago Orchestras include the Chicago Symphony Orchestra, the Chicago Opera Lyric, and the Chicago Symphony. The Lollapalooza, Smoke August, Peachfork, North Coast Music Festival, Rebellion Festival, Chicago House Music Festival, Chicago Religious Music Festival, Chicago Blues Festival, etc. are some of the most important music festivals in this city.
