What kinds of music have harmonica in them?
Harmonicas have been used in almost all styles of music. Of course pop, country, blues, folk music and jazz are the most obvious styles, but harmonicas are also heard in reggae and hip-hop settings. Also in classical music harmonicas are used, but unfortunately here the harmonica is often considered an inferior instrument. Also in classical music harmonica is a bit of an overloaded term. It can refer to lots of exotic instruments that can sound more notes at the same time, and that are not regularly found in a symphonic orchestra (glass harmonica).
