How does a harmonica work?

Answer
There are many types of harmonicas. I will describe to you how a
diatonic harmonica works.
A harmonica has a chambered body with each chamber containing 2
small metal reeds. The reeds are flipped in alignment from each
other.
As you blow into one of the chambers air passes over the first
reed and causes it to vibrate and this vibration causes the sound
you hear. As you draw air in through a chamber ("suck on a
harmonica") the air passes through the chamber in reverse and
causes the second reed to vibrate. because the reeds are aligned
oppisately - the air direction will determine which reed
vibrates.
Harmonicas use a series of reeds lined up from longer to
shorter. The shorter the reed - the higher the pitch of the note
sounded.
Some harmonicas use a wood body and some use plastic. There are
also synthetic and metal reeds, which affects the pitch.
Asked in Harps
Is a harmonica and blues harp the same thing?

Playing Harmonica and playing blues harp can be the same thing.
An Harmonica is a musical instrument and blues harp is a style of
harmonica playing. There are many kinds of harmonicas. The most
common type of harmonica has 10 holes and 20 reeds. This kind of
harmonica is monochromatic, that is, made for a certain musical
key. When a harmonica player plays a song in that musical key, it's
called "Straight" harp. However, a practitioner of the blues harp
style will play in the tonic key (C for example) and what is called
"second position". For the straight or tonic key of G, a C
harmonica would be the harp for playing in second position and
getting the bluesy sound. The blues sound is created by bending the
reeds and thus changing the note played on that reed when played in
the tonic key. Bending a note by blowing or sucking is a technique
mastered by the harp player and has nothing to do with taking the
harp (harmonica) apart and physically bending the reeds prior to
play.

How do you clean hohner marine band harmonica?

The Hohner harmonica website says...
"For the most part, cleaning your harmonica is not necessary and
should not be attempted. Parts of the instrument, including
the reeds, reed plates, valves, and comb are very delicate and
could damage easily. If you wish to clean the exterior parts such
as the covers, mouthpiece, slide, etc, use a soft cloth with either
soapy water or rubbing (isopropyl) alcohol. If you disassemble your
harmonica before cleaning, wait until the parts are completely dry
before reassembling."
Also, "Never soak, rinse, or boil a harmonica. A number of
harmonica instruction books and other sources recommend this
practice. However, soaking or boiling a harmonica will make painted
surfaces peel, cause the wooden combs to warp or crack, promote
corrosion of metal reeds and the reed plate, destroy the wind
saving valves and void the warranty. In short, soaking or boiling
your harmonica will damage it beyond repair."
Asked in Harmonica
What part of harmonica vibrates to produce sound?

It has multiple, variably-tuned brass or bronze reeds which are
secured at one end over an airway slot into which it can freely
vibrate. The vibrating reeds repeatedly interrupt the airstream to
produce sound.
The player selects the notes by the placement of his or her
mouth over the proper airways. These holes are usually made up of
discrete holes in the front of the instrument. Each hole
communicates with one or more reeds, depending on the type of
harmonica. Because a reed mounted above a slot is made to vibrate
more easily by air from above, reeds accessed by a mouthpiece hole
often may be selected further by choice of breath direction
(blowing, drawing). Some harmonicas, primarily the chromatic
harmonica, also include a spring-loaded button-actuated slide that,
when depressed, redirects the airflow.
