There are numerous techniques available for harmonica, including bending, overbending, and tongue blocking.
In addition to the 19 (draw 2 and blow 3 are the same pitch even though there are 10 holes) notes readily available on the diatonic harmonica, players can play other notes by adjusting their embouchure and forcing the reed to resonate at a different pitch. Although it is notoriously difficult and can be frustrating for beginners, one does this by relaxing and coordinating muscles in the throat, mouth, and lips. This technique is called "bending", a term borrowed from guitarists, who literally "bend" a string in order to create changes in pitch. Using bending, a player can reach all the notes on the chromatic scale. "Bending" also creates the glissando characteristic of much blues harp and country harmonica playing. Bending on a guitar bends the pitch upward. However, typically "bending" on a harmonica means the pitch falls downward. Bends are essential for most blues and rock harmonica due to the soulful sounds the instrument can bring out. The famous "wail" of the blues harp typically required bending.

The physics of bending are quite complex, but amount to this: a player can bend the pitch of the higher-tuned reed down toward the pitch of the lower-tuned reed in any given hole. In other words, on holes 1 through 6, the draw notes can be bent and on holes 7 through 10 the blow notes can be bent. Hole 3 allows for the most dramatic bending: in C, it is possible to bend 3 draw from a B down to a G♯, or anywhere in between.
In the 1970s, Howard Levy developed the "overbending" technique (also known as "overblowing" and "overdrawing"). Overbending, combined with bending, allowed players like Chris Michalek, Carlos del Junco, Otavio Castro and George Brooks to play the entire chromatic scale. When bending, the player forces the lower of the two reeds in a chamber to vibrate faster, while the higher pitched reed vibrates slower. When overbending, the player isolates the higher of the two reeds and by so doing can play higher pitched notes. By using both bending and overbending techniques a player can play the entire chromatic scale using a diatonic harmonica. This has allowed diatonic harmonica players to expand into areas traditionally viewed as inhospitable to the instrument such as jazz.
The overbend is a difficult technique to master. To facilitate overbending, many players use specially modified or customised harmonicas. Any harmonica can be set up for better overbending. The primary needs are tight tolerances between the reed and reed-plate and a general level of air-tightness between the reed-plate and comb. The former often necessitates lowering the "gap", the space between the tip of the reed and the reed-plate. Another often used technique called embossing is to make the space between the sides of the slots in the reed-plate and the reed itself as small as possible by drawing in the metal on the sides of the reed-plate slots towards the reed. While these modifications make the harmonica overbend more easily, overbending is often possible on stock diatonic harmonica, especially on an airtight design.

Although there are players who use precise overbends and bends to play the diatonic harmonica as a fully chromatic instrument, this is still very rare, not simply because the technique is very difficult, but also because it requires an extreme level of skill, as well as a perfectly setup instrument, to match the tone of an overbend to the sound of other normally played notes. Thus, even though a player could play any melody in any key (within a three octave range) on a C diatonic harmonica, most harmonica players (especially those who focus on blues and/or diatonic harmonicas) prefer to match the possibilities of glissandos, register and dynamics of a given melody to a harmonica. Thus, the common practice is still to use different keys of diatonic harmonicas; recently some also use valved diatonics or XB-40 for different songs. As for harmonica players who play mostly classical or jazz music, most would rather use chromatics, as those styles call for a more fully chromatic style.
However, more and more people are attempting to overblow, or at least trying to bend on all notes (using valves or the XB-40), on diatonics, since overbend and bending allow wailing, which is a desired aspect of many styles such as blues – something that is hard to simulate with chromatic harmonicas.
The vibrato might also be achieved via rapid glottal (vocal fold) opening and closing, especially on draws (inhalation) simultaneous to bending, or without bending. This obviates the need for cupping and waving the hands around the instrument during play.
Tongue blocking and lip pursing are two different ways of playing the harmonica with one's mouth. Tongue Blocking is when you put your mouth over three or more holes on the harmonica but you cover all the holes but one with your tongue. This technique gives you the ability to play a variety of sounds. Lip Pursing is playing a single note by pursing the lips and covering only one hole. The Tongue Blocking Technique is used by Little Walter, Sonny Boy Williamson I (John Lee Williamson), Sonny Boy Williamson II (Aleck Ford "Rice" Miller), Big Walter Horton, James Cotton, George Smith, Taj Mahal, among many others. The Lip Pursing Technique is used by Paul Butterfield, Junior Wells, Sugar Blue, Stevie Wonder, Jason Ricci among many others. [1]
In addition to playing the diatonic harmonica in its original key, it is also possible to play it in other keys by playing in other "positions", using different keynotes. Using just the basic notes on the instrument would mean playing in a specific mode for each position (e.g. playing in D Dorian or G mixolydian on a C Major harmonica), but techniques such as bending enable different modes to be used at each position (e.g. playing in E mixolydian on a C Major harmonica). Harmonica players (especially blues players) have developed a set of terminology around different "positions" which can be somewhat confusing to other musicians. There are twelve "natural positions" (one for each semitone), numbered from 1st position as given (on a standard 10-hole diatonic) by the note on the 1 blow and going up round the cycle of 5ths - so on a C harp, 1st position gives C, 2nd position G, 3rd D, 4th A etc. With this numbering system, positions 7-11 (on a C instrument, those having keynotes F♯, C♯, G♯, D♯, A♯) are based on notes only available by bending or overblowing. The terminology of positions is also applicable to chromatic harmonicas.
The first three positions cover the vast majority of harmonica playing, and these positions have names as well as numbers. They are:
The terminology for other positions is slightly more varied. It is possible, of course, to play in any of the modes and, using overblows and bends, it is possible to play in all 12 keys on a single diatonic harmonica, though this is very rarely done on a diatonic. Even if a player is capable of playing multiple keys on a single harmonica, they will usually switch harmonicas for different songs, choosing the right "position" for the right song so as to achieve the best sound. Even when the same notes can be achieved on a different key of harmonica, choosing different keys of harmonicas will offer a variety of options such as slides, bends, trills, overblows, overbends, and tongue splits. Breathing patterns are changed position to position, changing the difficulty of the transitions between one note to the next, and altering the ratio of blow notes and draw notes. The different starting place for each position limits or extends note options for the bottom and top octaves. Changing positions will allow the player to create a different sound overall.
Blues harp or cross harp denotes a playing technique that originated in the blues music culture, and refers to the diatonic harmonica itself, since this is the kind that is most commonly used to play blues. The traditional harmonica for blues playing was the Hohner Marine Band, which was affordable and easily obtainable in various keys even in the rural American South, and since its reeds could be "bent" (see below) without deteriorating at a too rapid rate.
A diatonic harmonica is designed to ease playing in one diatonic scale. Here is a standard diatonic harmonica's layout in the key of C (1 blow is middle C):
This layout easily allows the playing of notes most important in C major, that of the C major triad: C, E, and G. The tonic chord is played by blowing and the dominant chord is played by drawing.
Blues harp subverts the intention of this design with what is "perhaps the most striking example in all music of a thoroughly idiomatic technique that flatly contradicts everything that the instrument was designed for" (van der Merwe [2] p66), by making the "draw" notes the primary ones, since they are more easily bent (for holes 1-6) and consist (relative to the key of the harmonica) of II, V, VII, IV, and VI. In the case of a major C harmonica, this will be D, G, B, F, and A. This allows two things:
The player can play slurs or bends around the minor/major third of the scale and around the tritone/fifth of the scale, both of which are vital to many blues compositions. For a further discussion of "bending" on the harmonica, see the harmonica article.
The key played in this style is one fifth above the nominal tuning of the harmonica, e.g. a C harmonica is played in the key of G. Therefore, to be in tune with a normal guitar tuning of E, an A harmonica is often used. This is because by playing the C harmonica in G, or A harmonica in E, the dominant or seventh chord is produced in place of the tonic chord, and in the blues, all chords are typically played as dominant (seventh or ninth) chords.
This is playing in 2nd position, called "cross harp."
If we use a solo-tuned harmonica instead of richter-tuned, it will be in 3rd position, a ii-minor key. So in the case of a C harmonica, it will be in the key of D minor. This is called "slant harp." Minor keys can also be easily played in 4th and 5th positions.
Harmonica players disagree on the need to break-in the reeds of a new harmonica, and on break-in technique. Even among those that favor a break-in period, numerous techniques appear: some may prefer to play a new harmonica for several hours without bending notes; others prefer to play for many short periods of time with reasonable breaks in between, as recommended by acclaimed chromatic harmonica technician and player Douglas Tate. Some diatonic players use a 12 volt car vacuum to work the reeds, which is claimed to avoid premature stress cracks.
Although not generally recommended nowadays by either players or manufacturers, some past players have felt soaking their harmonicas in warm water, and even beer, whiskey, or vodka helped break them in, believing that this facilitates bending of the notes. This is done only with aged wood combed harmonicas; as the wood ages, it can shrink, and in the case of the Hohner Marine Band harmonica (or any harmonica with wooden parts) soaking causes the wood to swell and makes the instrument more airtight. The problem with this is that the wood has a tendency to swell and crack when it is soaked in any type of liquid.
In music theory, a diatonic scale is any heptatonic scale that includes five whole steps and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, depending on their position in the scale. This pattern ensures that, in a diatonic scale spanning more than one octave, all the half steps are maximally separated from each other.
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 distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep, bend, smear, rip, lip, plop, or falling hail.
The harmonica, also known as a French 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.
In music theory, the key of a piece is the group of pitches, or scale, that forms the basis of a musical composition in classical, Western art, and Western pop music.
Tonality or key: Music which uses the notes of a particular scale is said to be "in the key of" that scale or in the tonality of that scale.
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 harmonica; however, it lacks many characteristics of harmonicas.
A jazz scale is any musical scale used in jazz. Many "jazz scales" are common scales drawn from Western European classical music, including the diatonic, whole-tone, octatonic, and the modes of the ascending melodic minor. All of these scales were commonly used by late nineteenth and early twentieth-century composers such as Rimsky-Korsakov, Debussy, Ravel and Stravinsky, often in ways that directly anticipate jazz practice. Some jazz scales, such as the bebop scales, add additional chromatic passing tones to the familiar diatonic scales.
Chris "Buddha" Michalek was an American harmonica player.
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.
Chromaticism is a compositional technique interspersing the primary diatonic pitches and chords with other pitches of the chromatic scale. Chromaticism is in contrast or addition to tonality or diatonicism and modality. Chromatic elements are considered, "elaborations of or substitutions for diatonic scale members".
Not only at the beginning of a composition but also in the midst of it, each scale-step [degree] manifests an irresistible urge to attain the value of the tonic for itself as that of the strongest scale-step. If the composer yields to this urge of the scale-step within the diatonic system of which this scale-step forms part, I call this process tonicalization and the phenomenon itself chromatic.
Chromaticism is almost by definition an alteration of, an interpolation in or deviation from this basic diatonic organization.
Throughout the nineteenth century, composers felt free to alter any or all chord members of a given tertian structure [chord built from thirds] according to their compositional needs and dictates. Pronounced or continuous chordal alteration [and 'extension'] resulted in chromaticism. Chromaticism, together with frequent modulations and an abundance of non-harmonicism [non-chord tones], initially effected an expansion of the tertian system; the overuse of the procedures late in the century forewarned the decline and near collapse [atonality] of the system [tonality].
Chromaticism is the name given to the use of tones outside the major or minor scales. Chromatic tones began to appear in music long before the common-practice period, and by the beginning of that period were an important part of its melodic and harmonic resources. Chromatic tones arise in music partly from inflection [alteration] of scale degrees in the major and minor modes, partly from secondary dominant harmony, from a special vocabulary of altered chords, and from certain nonharmonic tones... Notes outside the scale do not necessarily affect the tonality...tonality is established by the progression of roots and the tonal functions of the chords, even though the details of the music may contain all the tones of the chromatic scale.
Sometimes...a melody based on a regular diatonic scale is laced with many accidentals, and although all 12 tones of the chromatic scale may appear, the tonal characteristics of the diatonic scale are maintained. ... Chromaticism [is t]he introduction of some pitches of the chromatic scale into music that is basically diatonic in orientation, or music that is based on the chromatic scale instead of the diatonic scales.
Mixolydian mode may refer to one of three things: the name applied to one of the ancient Greek harmoniai or tonoi, based on a particular octave species or scale; one of the medieval church modes; or a modern musical mode or diatonic scale, related to the medieval mode.
Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Since its foundation, and though known for its harmonicas, Hohner has manufactured a wide range of instruments, such as kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles
The Richter-tuned harmonica, or 10-hole harmonica or blues harp, is the most widely known type of harmonica. It is a variety of diatonic harmonica, with ten holes which offer the player 19 notes in a three-octave range.
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.
Tremolo harmonicas are 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".
Diatonic and chromatic are terms in music theory that are most often used to characterize scales, and 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.
Tablature is a form of musical notation indicating instrument fingering 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.
The Anglo or Anglo-German concertina is a member of the concertina family of free-reed instruments.
