Harmonica

The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument loved all around the world. It is a key part of many music styles, including blues, American folk music, classical music, jazz, country, and rock. There are several types of harmonicas, such as diatonic, chromatic, tremolo, octave, orchestral, and bass versions.

To play the harmonica, you use your lips and tongue to control the air moving in and out of holes on the mouthpiece. Each hole leads to a chamber with at least one reed—a thin, spring-like strip usually made of brass or steel. When you blow or draw air through a hole, the reed vibrates to create sound.

The reeds in a harmonica are tuned to specific notes by changing their length, weight, or stiffness. Longer, heavier, or more flexible reeds make lower notes, while shorter, lighter, or stiffer reeds make higher notes. Players can change the pitch of a note by adjusting their embouchure, or the way they hold their mouth and lips, a technique known as bending. This makes the harmonica a very expressive and versatile instrument.

Parts

The harmonica has three basic parts: the comb, reed plates, and cover plates.

Comb

The comb is the main body of the harmonica. It forms air chambers for the reeds when put together with the reed plates. Traditionally made from wood, combs are now also made from plastic or metal, like titanium for high-end instruments. Some players think the comb material changes the sound, while others do not. Wooden combs can absorb moisture from the player's breath, which might make the instrument uncomfortable to play.

Reed plate

The reed plate holds several reeds. Reeds are usually made of brass but can also be steel, aluminum, or plastic. Reeds on the inside of the plate respond to blowing, while those on the outside respond to sucking air in. Most harmonicas have reed plates screwed or bolted to the comb. This allows individual reeds to be replaced when they go out of tune.

Cover plates

Cover plates protect the reed plates and are usually made of metal, though wood and plastic are also used. They help project the sound and affect the harmonica's tone. There are open designs and enclosed designs, each offering different sound qualities.

Wind-savers

Wind-savers are small valves made from plastic, paper, leather, or Teflon. They are used in some harmonicas to stop air from leaking through unused reeds, helping to keep the sound clear.

Mouthpiece

The mouthpiece sits between the air chambers and the player's mouth. It can be part of the comb, part of the cover, or a separate piece. In some harmonicas, it helps hold a slide for changing notes.

Accessories

Amplification devices

Since the 1950s, many harmonica players have used microphones and amplifiers to make their sound louder. Early players used special microphones to give their harmonica a strong, clear sound. Amplifiers can add extra effects to the sound, making it richer and more powerful. Some players also use effects units like reverb and delay to change their tone.

Rack or holder

Some harmonica players use a special holder to keep the harmonica in place while they play other instruments, like a guitar. This holder clips the harmonica to the player's neck, freeing their hands for other instruments. Many famous musicians use these holders while performing.

Types

Chromatic

Main article: Chromatic harmonica

The chromatic harmonica can play all the notes, including flats and sharps, unlike other types. It has a sliding bar that changes which notes you can play. Some models let you change notes by moving the mouthpiece with your lips. The smaller models play in one key, but larger ones can play in any key. This type of harmonica is used in many styles of music.

Diatonic

Diatonic harmonicas are made to play in one key, but players can sometimes make it play in other keys by forcing certain notes. In different places, the term "diatonic harmonica" might mean different styles of harmonicas.

Here is the note layout for a standard diatonic in the key of G major:

Each hole is spaced the same distance apart, which helps determine the notes you can play.

Tremolo-tuned

Main article: Tremolo harmonica

The tremolo-tuned harmonica has two notes for each hole, one slightly higher and one slightly lower in pitch. This creates a special wavering sound. The version used in East Asia can play all 12 notes and is often used in rock and pop music.

Orchestral

Orchestral harmonicas are made for playing in groups.

Melody

There are several types of orchestral melody harmonicas. The most common are horn harmonicas, often found in East Asia. These have a single large part with notes on the top and bottom. Some versions are laid out like a piano. Horn harmonicas can play notes from two to three octaves and are often used in East Asian harmonica orchestras. They have a different sound and can replace brass instruments.

Another type is the polyphonia, which has all 12 notes in a row. Some of these can play both when you blow and when you draw.

Chord

The chord harmonica can play up to 48 different chords, such as major, minor, and seventh chords, for group playing. Each hole can play different chords when you blow or draw. Some models can also play bass notes along with chords. There are different kinds of chord harmonicas, including ones that work like chromatic harmonicas.

The Suzuki SSCH-56 Compact Chord harmonica is a 48-chord harmonica that uses a chromatic harmonica body. It plays different chords on each hole, repeating the pattern multiple times.

ChengGong

The ChengGong harmonica has a main body and a sliding mouthpiece. The body has 24 holes and can play notes from B₂ to D₆. The sliding mouthpiece gives many chord options and can also play single notes and double stops over three octaves. Blowing and drawing produce the same notes on this harmonica.

Pitch pipe

The pitch pipe is a special type of harmonica that gives a reference note for singers and other instruments. Some early pitch-pipes are very similar to harmonicas but are named differently based on who they were made for. Chromatic pitch pipes give a full octave of notes and are used by singers and choirs. Other pitch pipes are made for string players like violinists and guitarists, providing notes matching their instrument's open strings.

Techniques

Vibrato is a fun way to make your harmonica notes sound shaky. You can do this by moving your hands around the harmonica quickly or by using your voice to change the sound while you play. Another way to make a shaky sound is by moving your lips fast between two holes, like shaking your head or moving the harmonica side to side.

Players can make new notes by changing how they hold their mouth and making the harmonica sound at different pitches. This is called bending. Bending helps create special sounds in blues and rock music. In the 1970s, a player named Howard Levy invented over bending, which lets musicians play many different notes.

Players can also change the sound by playing the harmonica in different ways, called "positions". Each position gives a different musical feel. Some players like to change the size of their mouth to bring out certain sounds, but they need to be careful to keep the music sounding good.

When harmonica players use microphones, they can make their sound even bigger by how they hold their hands and how they breathe into the microphone.

History

The harmonica was created in Europe during the early 1800s. Instruments that used free reeds, like the Chinese sheng, had been played in East Asia for a very long time. These instruments became better known in Europe after a French priest named Jean Joseph Marie Amiot shared them. Around 1820, people in Europe began making new designs. Christian Friedrich Ludwig Buschmann is often called the inventor of the harmonica in 1821, but others made similar instruments around the same time. In 1829, Charles Wheatstone made a mouth organ called the "Aeolina."

The harmonica first appeared in Vienna, where people sold harmonicas with special chambers before 1824. A tuning method called Richter tuning was invented in 1826 and became very popular. In Germany, a violin maker named Johann Georg Meisel copied harmonicas and began making them. Other places like Bohemia also started making harmonicas.

In 1857, a clockmaker named Matthias Hohner began making harmonicas and was the first to make them on a large scale. By the 1920s, the diatonic harmonica looked much like it does today. New types like tremolo and octave harmonicas came later.

By the late 1800s, making harmonicas was a big business. In the 1900s, new designs like the chromatic harmonica were made. Today, new designs continue to appear.

Some famous people, like US president Abraham Lincoln, played harmonicas. During World War II, making harmonicas was hard because materials were needed for the war. A man named Finn Haakon Magnus created plastic harmonicas, which were easier to make and became popular, especially with children.

Medical use

Playing the harmonica can help build strong breathing muscles. It’s like doing special exercises that doctors use to help people who have trouble breathing. This can be very useful for patients learning to breathe better after an illness.

When President Ronald Reagan had a health problem in 1981, his breathing therapist used a harmonica to help him practice. The therapist hoped to play at the White House with his orchestra, but this did not happen.

Related instruments

The concertina, diatonic and chromatic accordions, and the melodica are all instruments like the harmonica. They make sound in a similar way. In some languages, these instruments have names that sound very similar to each other.

The glass harmonica, invented by Benjamin Franklin in 1761, has "harmonica" in its name but works very differently. It uses glass cups that spin and make music when touched with wet fingers.
