History• Many instruments have been called “harmonica” or

“mouth organ”, before the advent of the modern harmonica.

• 3000 BC: Free-reed instruments were used in China and Asia (e.g. the sheng)

• 1800’s: Modern diatonic harmonicas appeared .– 1821 Christian Buschman pitchpipe converted to instrument.– 1825-26 Richter 20 reeds in 10 holes ”mundharmonika”.– 1857 Matthias Hohner, a clock maker in Trossingen,

Germany, began manufacturing harmonicas full time.
