Peter R. Egbert MDProfessor of Ophthalmology, Emeritus
Department Chair, EmeritusStanford University
• I have no conflict of interest or financial disclosures for this presentation
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.
Hohner Harmonica Company Trossigen, Germany
• 1862-- first to export to North America• 1890-- 1,000,000/year• 1907-- 7,000,000 annually; 887,000
reeds from 15 tons of brass each day.–Many different models
• Today many competitors– Lee Oscar, Seydel, Huang, etc.
Most popular musical instrument?
• “The only thing rarer than a person who has never owned a harmonica is a person who does it justice.”
• “You cannot be everywhere unless you can go everywhere.”– Portable, sturdy
• “An accordion with soul.”– Draw and blow notes– Breathe and play

Standard tuning
The 10 hole diatonic harmonica is a transposing instrument with various keys.
Note that the chord degrees are the same on all the harmonicas.
Two main embouchures• Tongue block– The lips cover up to 4 holes.– The tongue blocks all but the right hole
(see MRI).
• Pucker or lip block. – The lips cover all but one hole.
