Matthias Hohner was apparently not a very good harmonica player, however he was an excellent businessman. He bought out his competitors, and in 1862 began exporting harmonicas to the United States, which soon became his largest market. Hohner continued to expand the business, and in 1900 he handed it over to his 5 sons.
Throughout the first half of the 20th century, the popularity of the harmonica continue to grow. In particular, harmonica bands, with many people playing together, were very popular. The Chromatic harmonica, which include a buttom on the side, allowing all notes to be played, was developed by Hohner. In the 1930’s, Larry Adler became the most famous player of this instrument, and remained so until his death in 2001.
The
Blues
In the United States, the harmonica became very popular as a blues instrument. In the 1930’s and early 1940’s a man named John Lee "Sonny Boy" Williamson became well known. After the second world war, Chicago became a major centre for blues, with great players such as Rice Miller (Sonny Boy Williamsom II) and Little Walter. Many people consider Little Walter to be the greatest blues harmonica player. He died in 1968, a sad day in the history of the harmonica.
While the harmonica has been known mostly as a blues instrument, many people were introduced to the harmonica in the 1960’s through the folk music of Bob Dylan.
