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 Cologne
Cologne, once home to the Popkomm pop show and the German rock center from BAP to Klaus Lage is now less active in the music industry. Many independent artists, such as Peter Leach, Kelly, or Erdobble, appreciate this far-fetched position for its freedom. The father of pop music in Cologne are members of the international rock band Can. The genre of rock in music, which originated in the early 1970s, is now world-renowned. In addition, the city is very popular due to various music carnivals.
