The Richter-tuned harmonica, 10-hole harmonica (in Asia) or blues harp (in America), is the most widely known type of harmonica. It is a variety of diatonic harmonica, with ten holes which offer the player 19 notes (10 holes times a draw and a blow for each hole minus one repeated note) in a three-octave range.
The standard diatonic harmonica is designed to allow a player to play chords and melody in a single key. Because they are only designed to be played in a single key at a time, diatonic harmonicas are available in all keys. Harps labeled G through B start (on hole 1 blow) below middle C, while Harps labeled D♭ through F♯ start above middle C (C4). Here is the layout for a standard diatonic harmonica, labeled C, starting on middle C (C4).
Although there are three octaves between 1 and 10 "blow", there is only one full major scale available on the harmonica, between holes 4 and 7. The lower holes are designed around the tonic (C major) and dominant (G major) chords, allowing a player to play these chords underneath a melody by blocking or unblocking the lower holes with the tongue. The most important notes (the tonic triad C–E–G) are given the blow, and the secondary notes (B–D–F–A), the draw.
Valved diatonics
The valved diatonic is one of the most common ways of playing chromatic scales on diatonic harmonicas. While chromatic is available, valved diatonic is also common, and there are reasons to use a valved diatonic rather than chromatics. It does not have a slide assembly (so that it has less air leakage), and it has a wider tonal range and dynamic. As well, it has a smaller size and is much more suitable to use with microphone, and it is still cheaper than chromatic, even for a premade one like Hohner's Auto Valve or Suzuki's Promaster MR-350v.
Half-Valved diatonics are made by fitting windsavers on half the lower reed in each opening: draw holes 1–6 and blow holes 7–10; this way, all these reeds can be bent down a semitone at least, although most players can easily bend down a whole tone. Alternatively, one can simply buy a factory-made valved diatonic such as the Suzuki Promaster Valved.
Some disadvantages of the valved diatonic is that the valves prevent other bending techniques, such as overblowing, and sound different than traditional draw bends due to the valved bends being single-reed bends. One way to address the latter is by having an additional reed that activates when one bends a note; this is the philosophy of Hohner's XB-40 and Suzuki's SUB30 Ultrabend.
Development/Playing in different keys
Aside from bending, Richter-tuned harmonicas are modal.
Playing the harmonica in the key to which it is tuned is known as "straight harp" or "first position" playing. For example, playing music in the key of C on a C-tuned harmonica.
More common (especially in blues and rock) is "crossharp" or "second position" playing which involves playing in the key which is a perfect fourth below the key of the harmonica (for example, on a C tuned harmonica, a second position blues would be in G—resulting in the instrument playing in mixolydian mode). This is because the notes of the G pentatonic scale (a commonly used scale in blues and rock) are more easily accessible on a C-tuned harmonica. The lower notes of harps in the lower keys (G through C) are easier to bend, but take more wind. Since much of crossharp is played on the inhalation, every opportunity for exhalation must be capitalized upon—by heavily exhaling on every exhaled note and during every pause. Crossharp lends itself to seventh and ninth chords (particularly G7 and G9) as well as blue notes (particularly on D chords, where the harmonica is tuned to play D minor while the other instruments play D major).
Another method is to play in the key one whole tone above that of the harmonica. On a C-tuned harmonica, this would mean playing in the key of D. This is known as "slant harp" or "third position" playing, and results in the harmonica playing in dorian mode. This is much less intuitive as it requires the ability to bend notes completely accurately, and there are fewer useful chords available than in first or second-position playing. The technique offers many notes that are not achievable in the other positions without overblows, such as the blue note on the third degree, which may or may not be favorable depending on the circumstance. The bends available at the lower end of the instrument also make playing melodies in a D major scale relatively easy for those who have any semblance of proficiency at the bending technique, though most of the notes (all but the second and fourth, E and G) in the scale are on the draw, requiring great skill and strategy in exhaling, even more so than in crossharp.
Continuing along the circle of fifths, fourth position, fifth position, sixth position and zeroth positions can be played, with the scales played in those positions indicated as follows:
Note that using blue notes, any of the seven positions can be used over music in its corresponding major scale if only the notes in the corresponding pentatonic scale are played.
Specially tuned instruments
Some players prefer specially tuned variants of the diatonic harmonica. Several manufacturers, for instance Lee Oskar Harmonicas, make a variety of harmonicas to help players used to a "cross-harp" style to play in other styles. Cross-harp players usually base their play around a mixolydian scale starting on 2 draw and ending a 6 blow (with a bend needed to get the second tone of the scale; a full scale can be played from 6 blow to 9 blow). Lee Oskar specially tunes harmonicas to allow players to play a natural minor or major scale from 2 draw to 6 blow, or a harmonic minor scale from 4 blow to 7 blow. Below are some sample layouts (the key labels describe the scale from 2 draw to 6 blow, whereas traditional harmonicas are labelled according to the scale between 4 and 8 blow).

With the major second on 3 blow (where, in standard Richter tuning, the cross harp tonic would be repeated) and a major 7th (rather than a minor 7th) on 5 draw, the Melody Maker has a full major scale. This can be very useful for playing major key melodies, for example, fiddle tunes, quickly, without having to do a lot of precise bending or overblowing. This tuning, designed and marketed by Lee Oskar, is a particularly interesting evolution of the harmonica, since it allows a player accustomed to playing "cross harp" (in Mixolydian) to play in a major key (which is what the standard layout is designed for in the first place). Rather than providing the standard tonic C and dominant G7 chords, the Melody Maker provides a GM7 chord (2–5 draw), a C6 chord (1–4 blow), an Am or Am7 chord (3–5 or 3–6 blow), a D chord (4–6 draw) and a C chord (6–10 blow). If we are in the key of G, then, the melody maker provides the I chord, the IV chord, the V chord and the ii chord, allowing ii–V–I progressions as well as I–IV–V progressions.

It is also possible for harp players to tune the harmonica themselves. By making small scratches in a reed, the note played can be changed. It is possible to either get a higher or a lower note. Some harp players make extensive use of these modifications. One of the most famous examples is the harp solo on "On the Road Again" by Canned Heat,[1] on which the harmonicist, Alan "Blind Owl" Wilson, gets the minor third crossharp on the sixth drawn reed, which is normally the major second crossharp. There are books, toolkits and guides to tuning and harp customization available on the Internet; anyone interested in trying their hand at tuning should be prepared to sacrifice a few harmonicas during the learning process.
12-hole and 14-hole diatonic
Hohner had made a few non-standard harmonicas. All of them have more than 10 holes and are labeled "grosse richter". For 12 holes, Hohner makes the M364 Marine Band, as well as the M36460 Marine Band Soloist. The Marine Band Soloist is solo tuned, with 3 full diatonic octaves with all notes of the major scale of the key of C. Since it can bend notes in the same way as a regular diatonic harmonica in the middle octave, some players use this for blues (and even jazz) instead of the more well-known solo-tuned harmonica, the chromatic harmonica, since the bent notes sound very different from true semi-tones. (For layout, see below at Chromatic harmonica, key out) In this configuration, blues players usually play in the third position, the D-minor blue scale.
In addition to the M364 models with 12 holes, there is also the Hohner Marine Band M365 14-hole harmonica. The general dimensions of the 12- and 14- hole Hohner harmonicas are a bit bigger than regular diatonic harmonicas. The M36401 and M36501 harmonicas (in the key of C) are pitched one octave lower than the standard 10-hole C diatonic. Thus, hole-4 blow is the same pitch as hole-1 on a regular diatonic harmonica in the key of C. The Marine Band M36408 and M36508 (in G) are similar to a usual G diatonic, having the higher end expanded.
Holes 1 through 4 and 6 are draw-bendable, and holes 8 through 14 are blow-bendable. Note the extra holes 11–14 which in theory extend the bending capabilities a lot (from A down to E in hole-14, for example), although in practice these are quite limited.

This harmonica offers many interesting possibilities, especially for blues harmonica, like extended tongue-block octave playing, the possibility to play exactly the same second-position riffs in two octaves, etc.
Extra-reed harmonicas
Two harmonica models have been released with altered designs that allow for increased bending abilities, and in effect, chromatic playing on a diatonic harmonica. They are often referred to as "extra-reed" harmonicas, because they carry more than the usual 20 reeds of a diatonic harp.
The Hohner XB-40, invented by Rick Epping, features an entirely new body design, though in practice, it is still a Richter-tuned (diatonic) harmonica. Here the blow reeds and the draw reeds are sealed off one from another with valves, effectively creating two separate cells in the comb for each hole in the mouthpiece: one for blow and another for draw. A second reed is then placed in this cell at a zero-offset (no gapping) so that it does not sound under normal playing. However, it is placed on the opposite side of the reed-plate from the speaking reed and tuned so that it responds when the player “bends” the note downwards in pitch. This allows for every note on the XB-40 to be bent downwards a whole-tone or more, whereas on standard diatonics only certain notes (the higher-pitched in the cell) will bend at all.

Blues harp player
Sonny Boy Williamson I created basics of blues harp play style. He was killed during a robbery. After that Rice Miller, better known as Sonny Boy Williamson II, is one of the most important harmonicists of this era.[2] Using a full blues band, he became one of the most popular acts in the South due to his daily broadcasts on the 'King Biscuit Hour', originating live from Helena, Arkansas. He also helped make popular the cross-harp technique, opening the possibilities of harp playing to new heights. This technique has now become one of the most important blues harmonica methods. Sonny Boy Williamson II used hand effects to give a very talkative feel to his harp playing. A number of his compositions have also become standards in the blues world. Williamson had a powerful sound and extended his influence on the young British white blues rockers in the 1960s, recording with Eric Clapton and The Yardbirds and appearing on live British television.
But Williamson was not the only innovator of his time. A young harmonicist by the name of Marion "Little Walter" Jacobs would completely revolutionize the instrument. He had new idea of playing the harmonica near a microphone. Big Walter Horton, Carey Bell, Sonny Terry(1911 - 1986), Junior Wells (1934 - 1998), James Cotton, Sugar Blue, Snooky Pryor, and Little Sonny were blues harp players also. Blues guitarist Jimmy Reed (1925 - 1976) sometimes played blues harp.

In music, a glissando is a glide from one pitch to another. It is an Italianized musical term derived from the French glisser, "to glide". In some contexts, it is equivalent to portamento, which is a continuous, seamless glide between notes. In other contexts, it refers to discrete, stepped glides across notes, such as on a piano. Some terms that are similar or equivalent in some contexts are slide, sweepbend, smear, rip, lip, plop, or falling hail. On wind instruments, a scoop is a glissando ascending to the onset of a note achieved entirely with the embouchure, except on instruments that have a slide.
The harmonica, also known as a French harp, mouth harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth to direct air into or out of one holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound.
A pitch pipe is a small device used to provide a pitch reference for musicians. Although it may be described as a musical instrument, it is not typically used to play music as such. Technically, it is a tuning harmonica; however, it lacks many characteristics of harmonicas.
An autoharp or chord zither is a string instrument belonging to the zither family. It uses a series of bars individually configured to mute all strings other than those needed for the intended chord. The term autoharp was once a trademark of the Oscar Schmidt company, but has become a generic designation for all such instruments, regardless of manufacturer.
Overblowing is the manipulation of supplied air through a wind instrument that causes the sounded pitch to jump to a higher one without a fingering change or the operation of a slide. Overblowing may involve a change in the air pressure, in the point at which the air is directed, or in the resonance characteristics of the chamber formed by the mouth and throat of the player.
A mouth organ is any free reed aerophone with one or more air chambers fitted with a free reed. Though it spans many traditions, it is played universally the same way by the musician placing their lips over a chamber or holes in the instrument, and blowing or sucking air to create a sound. Many of the chambers can be played together or each individually.
Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). It is a subsidiary of Matth. Hohner AG. The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Hohner has manufactured a wide range of instruments, such as harmonicas, kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles. Hohner is known mostly for its harmonicas.
There are numerous techniques available for playing the harmonica, including bending, overbending, and tongue blocking.
A button accordion is a type of accordion on which the melody-side keyboard consists of a series of buttons. This differs from the piano accordion, which has piano-style keys. Erich von Hornbostel and Curt Sachs categorize it as a free reed aerophone in their classification of instruments, published in 1914. The sound from the instrument is produced by the vibration of air in reeds. Button accordions of various types are particularly common in European countries and countries where European people settled. The button accordion is often confused with the concertina; the button accordion's buttons are on the front of the instrument, where as the concertina's are on the sides and pushed in parallel with the bellows.
A melodeon or diatonic button accordion is a member of the free-reed aerophone family of musical instruments. It is a type of button accordion on which the melody-side keyboard contains one or more rows of buttons, with each row producing the notes of a single diatonic scale. The buttons on the bass-side keyboard are most commonly arranged in pairs, with one button of a pair sounding the fundamental of a chord and the other the corresponding major triad.
The chromatic harmonica is a type of harmonica that uses a button-activated sliding bar to redirect air from the hole in the mouthpiece to the selected reed-plate desired. When the button is not pressed, an altered diatonic major scale of the key of the harmonica is available, while depressing the button accesses the same scale a semitone higher in each hole. Thus, the instrument is capable of playing the 12 notes of the Western chromatic scale. The chromatic harmonica can thus be contrasted with a standard harmonica, which can play only the notes in a given musical key.
A tremolo harmonica is a type of diatonic harmonica, distinct by having two reeds per note. In a tremolo harmonica, the two reeds are tuned slightly off a reference pitch, one slightly sharp and the other slightly flat. This gives a unique wavering or warbling sound created by the two reeds being not exactly in tune with each other and difference in their subsequent waveforms acting against one another. The degree of beating can be varied depending on the desired effect. Instruments where the beating is faster due to the reeds being farther apart from the reference pitch are called "wet", whereas those where the beating is slower and less noticeable due to the reeds being more closely in tune are called "dry".
Christian August Seydel founded the C. A. Seydel Söhne harmonica factory in Klingenthal, Sachsen in 1847. The firm remains the oldest harmonica factory in the world and manufactures a wide range of harmonicas.
Diatonic and chromatic are terms in music theory that are used to characterize scales. The terms are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900.
A hydraulophone is a tonal acoustic musical instrument played by direct physical contact with water where sound is generated or affected hydraulically. The hydraulophone was described and named by Steve Mann in 2005, and patented in 2011. Typically, sound is produced by the same hydraulic fluid in contact with the player's fingers. It has been used as a sensory exploration device for low-vision individuals.
The Schwyzerörgeli is a type of diatonic button accordion used in Swiss folk music. The name derives from the town/canton of Schwyz where it was developed. Örgeli is the diminutive form of the word Orgel (organ). Outside of Switzerland the instrument is not well known and is hard to find.
Tablature is a form of musical notation indicating instrument fingering or the location of the played notes rather than musical pitches.
Richter tuning is a system of choosing the reeds for a diatonic wind instrument. It is named after Joseph Richter, a Bohemian instrument maker who adopted the tuning for his harmonicas in the early 19th century and is credited with inventing the blow/draw mechanism that allows the harmonica to play different notes when the air is drawn instead of blown.
Solo tuning is a system of choosing the reeds for a diatonic wind instrument to fit a pattern where blow notes repeat a sequence of
The Anglo or Anglo-German concertina is a member of the concertina family of free-reed instruments.
