Construction and Manner of Playing

The shamisen comes in a number of forms, including nagauta shamisen (used chiefly in kabuki, and in contexts related to the pleasure quarters), gidayû shamisen (used chiefly in the puppet theatre), and tsugaru shamisen (a more recently developed instrument central to a folk musical tradition of Aomori prefecture ). These differ mainly in the length and thickness of the neck, size of the body of the instrument, and in the tuning. For the most part, however, they all share the same basic form, namely that of a three-stringed wooden instrument with a square body, employing catskin on the body [2] , and struck with a large plectrum called a bachi . The various types of shamisen used in the kabuki theater differ in the thickness of their necks, and certain other aspects, but all have the same length neck, and hence the same length strings (roughly 62cm).

• The jiuta style is said to be a more refined style, "though still conveying a subtle understated eroticism."

• The gidayû shamisen has a heavier bachi , heavier strings, and thicker neck ( futozao ) than the nagauta shamisen , and is tuned to deeper (lower) pitches. It is said to have a more masculine sound, and is played in a sparser manner, which is said to be "the most evocative and sexy."

• The nagauta shamisen is the lightest of the major types of shamisen, with the narrowest neck ( hosozao ) and is said to allow for "more instrumental virtuosity." As the chief instrument used in kabuki, it is played in a wide range of modes, including very slow, regular songs, but can also be played quite rapidly, employing a variety of accenting techniques.

• The tokiwazu-bushi style, and some jôruri styles outside of gidayû-bushi , make use of a chûzao (medium-thickness necked) shamisen.

• The Tsugaru-jamisen is the largest and heaviest type of shamisen. It is only rarely accompanied by song, though vocal shouts and calls (such as yoo~ and hup ) are an integral part of its distinctive "densely textured and rhythmically complex" style. Tsugaru-jamisen incorporates more percussive elements (using the bachi to strike the skin of the instrument, or the strings, without playing a specific note) than most other shamisen styles, as well as playing the strings with the left (fingering) hand, without using the bachi .

The shamisen is largely a monophonic instrument, meaning that only one note is struck at once; it does not rely on chords as does the modern/Western guitar. Reverberations, known as sawari , which occur when the bachi strikes the strings, or the body of the instrument, are essential to the distinctive " shibui " (bittersweet) sound of the instrument, though this is generally considered undesirable in Western music. Such reverberations are strongest in the tokiwazu , kiyomoto , gidayû , and Tsugaru styles, and weakest in the nagauta , jiuta , and kouta modes. Shamisen music is also traditionally heterophonic, meaning that the pitches sung do not directly correspond to the notes played on the instrument at that moment; the Japanese term tsukazu hanarezu is used to refer to the way shamisen music and its accompanying vocals typically follow the same melody line, for the most part, but are off from one another by a half-beat or more. This is a typical feature not only of certain genres of shamisen music, but of Edo period popular songs in general, including as well those songs accompanied on the koto .

Shamisen players employ tabulature, not absolute pitch, in their notation, but the tuning of the instruments, naturally, corresponds to certain pitches as understood in Western notation. The most common tunings are called honchôshi (lit. "core/basic tuning"), in which the three strings are tuned to B-E-B on the Western scale; niagari , in which the second (middle) string is raised up to F sharp; and sansagari , in which the bottom (highest pitched) string is lowered, such that the three strings are tuned to B-E-A.

The shamisen is believed to have first emerged in Japan in the late 16th century, being developed out of the snakeskin sanshin introduced to Japan from Okinawa at that time; the sanshin derived, in turn, from the Chinese sanxian , likely introduced into Okinawa in the late 14th century. The Okinawan sanshin is believed to have been introduced to the Japanese port of Sakai (near Osaka ) sometime around 1558 - 1567 ; the Japanese form of the instrument developed and spread quickly, spreading throughout Japan by around 1595 .

Following its appearance, the shamisen quickly became incorporated into a variety of popular entertainment modes and traditions, eventually being adopted into the kabuki and puppet theatres, and geisha and courtesan teahouses, though it was never adopted into more elite contexts such as the Noh theatre. Some of the earliest genres that made use of the shamisen include jiuta and kouta (parlor songs often accompanying dances), zokkyoku (one of the chief styles of geisha music), and the sekkyô-bushi and jôruri storytelling modes. The ningyô jôruri puppet theater incorporated the shamisen from the very beginning, around the year 1600 , developing its own distinctive genre ( gidayû-bushi ) and indeed its own distinctive style of instrument (the gidayû shamisen ) by the early 18th century. Meanwhile, though it has been suggested that the shamisen was not initially incorporated into onna kabuki (women's kabuki) in the early 17th century, it became the central musical instrument in kabuki by the 1650s. [5]

The shamisen was strongly associated with the so-called "floating world" of Edo period urban popular culture, and with the popular aesthetic known as iki or sui . However, while it may have been a key element of the aesthetic of "cool" or "chic" in the Edo period, some scholars argue that it was because of this very same strong association with low-class, popular culture (and not elite culture) that shamisen music was during the Meiji period not raised up as a celebrated example of traditional Japanese music, and that Japan instead turned away from these traditions and embraced Western classical music as strongly as it did.

The shamisen is used in a wide variety of styles and genres of music, including popular and folk styles, as well as in the kabuki and puppet theatres, geisha traditions (and, formerly, in the red light districts), and traditional ( hôgaku ) and neo-traditional ( shin-hôgaku ) concert traditions.

Styles or genres employed in the kabuki theatre, and in traditional dance derived from kabuki ( Nihon buyô ) include nagauta , tokiwazu , kiyomoto , and gidayû-bushi ; the latter is the chief style employed in the ningyô jôruri ( bunraku ) puppet theater.

Styles of short lyric songs accompanied on shamisen which were popular in the licensed quarters of the Edo period included kouta , hauta , utazawa , dodoitsu , and zokkyoku , among others. Kouta , which formed the basis of kabuki music before the advent of nagauta , along with hauta , were later incorporated into nagauta , jôruri , folk, and popular music. Kouta remains a prominent element of the geisha musical repertoire today, and while a number of styles classified as kokyoku ("old songs") are no longer performed in the theater, they continue to be performed in concerts and recitals.

When performed in concert, nagauta is often accompanied by hayashi (an ensemble of drums, flutes, and sometimes other instruments, derived from kabuki); unlike many other theatrical musical styles, nagauta has grown into a musical style in its own right, with many schools and individual performers eschewing connections to theater and dance, viewing musical accompaniment as a lesser activity than performing concerts where the music is the primary focus. Though the tokiwazu and kiyomoto styles often serve as accompaniment for theater and dance, when these styles are performed in a concert context, they are much less likely than nagauta to incorporate hayashi or dance, focusing instead solely on the vocal singing and shamisen playing.
