Pizzicato (//; Italian: pizzicato, translated as pinched, and sometimes roughly as plucked) is a playing technique that involves plucking the strings of a string instrument. The exact technique varies somewhat depending on the type of stringed instrument.
When a string is struck or plucked, as with pizzicato, sound waves are generated that do not belong to a harmonic series as when a string is bowed. This complex timbre is called inharmonicity. The inharmonicity of a string depends on its physical characteristics, such as tension, stiffness, and length. The inharmonicity disappears when strings are bowed because the bow's stick-slip action is periodic, so it drives all of the resonances of the string at exactly harmonic ratios, even if it has to drive them slightly off their natural frequency.
The first recognised use of pizzicato in classical music is in Claudio Monteverdi's Il combattimento di Tancredi e Clorinda (around 1638), in which the players are instructed to use two fingers of their right hand to pluck the strings. However in Tobias Hume's Captain Humes Poeticall Musicke (1607) Hume instructs the viola da gamba player to use pizzicato ('thumpe'). Later, in 1756, Leopold Mozart in his Versuch einer gründlichen Violinschule instructs the player to use the index finger of the right hand. This has remained the most usual way to execute a pizzicato, though sometimes the middle finger is used. The bow is held in the hand at the same time unless there is enough time to put it down and pick it up again between bowed passages. Unless necessary, avoid picking the strings too hard, or else resulting in a unpleasing slap sound on the instrument.
In jazz and bluegrass, and the few popular music styles which use double bass (such as french modern chanson, american psychobilly and rockabilly), pizzicato is the usual way to play the double bass. This is unusual for a violin-family instrument, because regardless whether violin-family instruments are being used in jazz (e.g., jazz violin), popular, traditional (e.g., Bluegrass fiddle) or Classical music, they are usually played with the bow for most of a performance. In Classical double bass playing, pizzicato are often performed with the bow being held in the hand; as such, the string is usually only plucked with a single finger. In contrast, in jazz, bluegrass, and other non-Classical styles, the player is not usually holding a bow, so they are free to use two or three fingers to pluck the string.
In classical music, however, string instruments are most usually played with the bow, and composers give specific indications to play pizzicato where required. Pieces in classical music that are played entirely pizzicato include:
Antonio Vivaldi, in the "Ah Ch'Infelice Sempre" section of his cantata Cessate, omai cessate, combined both pizzicato and bowed instruments to create a unique sound. He also included pizzicato in the second movement of "Winter" from The Four Seasons.
In music notation, a composer will normally indicate the performer should use pizzicato with the abbreviation pizz. A return to bowing is indicated by the Italian term arco. A left hand pizzicato is usually indicated by writing a small cross above the note, and a Bartók pizzicato is often indicated by a circle with a small vertical line through the top of it above the note in question or by writing Bartók pizz at the start of the relevant passage.
If a string player has to play pizzicato for a long period of time, the performer may put down the bow. Violinists and violists may also hold the instrument in the "banjo position" (resting horizontally on the lap), and pluck the strings with the thumb of the right hand. This technique is rarely used, and usually only in movements which are pizzicato throughout. A technique similar to this, where the strings are actually strummed like a guitar, is called for in the 4th movement of Rimsky-Korsakov's Capriccio Espagnol (Scena e canto gitano), where the violins and cellos are instructed to play pizzicato "quasi guitara"; the music here consists of three- and four-note chords, which are fingered and strummed much like the instrument being imitated.
Another colorful pizzicato technique used in the same Rimsky-Korsakov piece mentioned above is two-handed pizzicato, indicated by the markings m.s. and m.d. (for mano sinistra, left hand, and mano destra, right hand); here, the open E string is plucked alternately in rapid succession by the left and right hands.
One can also use the left hand fingers for pizzicato, either when they are not in use or as they are leaving their previous position. This allows pizzicati in places where there would not normally be time to bring the right hand from or to the bowing position. Use of left-hand pizzicato is relatively uncommon and is most often found in the violin solo repertoire; two famous examples of left-hand pizzicato are Paganini's 24th Caprice and Sarasate's Zigeunerweisen. Left hand pizzicato can also be used while bowed notes are being held, an effect appearing primarily in repertoire of the late 19th century and beyond. Examples of this technique can be found in the works of Wieniawski, Berg (Violin Concerto), Stravinsky (Three Pieces for String Quartet) and many others.
Maurice Delage calls for slurred pizzicati in the cello part of his Quatre poèmes hindous for soprano and chamber orchestra. This is achieved by playing one note, and then stopping a new note on the same string without plucking the string again. This technique (known as "hammering-on" to guitarists) is rarely used on bowed instruments.
A further variation is a particularly strong pizzicato where the string is plucked vertically by snapping and rebounds off the fingerboard of the instrument. This is sometimes known as the Bartók pizzicato, after one of the first composers to use it extensively. Gustav Mahler famously employs a Bartók pizzicato in the third movement of his Seventh Symphony, in which he provides the cellos and double basses with the footnote 'pluck so hard that the strings hit the wood' (bar 401). On the double bass, this style of snap pizzicato, or "slapping", was used in jazz since the 1920s and later used in rockabilly. Because an unamplified double bass is generally the quietest instrument in a jazz band, many players of the 1920s and 1930s used the slap style, slapping and pulling the strings so that they make a rhythmic "slap" sound against the fingerboard. The slap style cuts through the sound of a band better than simply plucking the strings, and allowed the bass to be more easily heard on early sound recordings, as the recording equipment of that time did not favor low frequencies. Pizzicato is also known as plucking to many people; arco is playing with the regular horse-haired bow.
Bartók also made use of pizzicato glissandi, executed by plucking a note and then sliding the stopping finger up or down the string. This technique can be heard in his Music for Strings, Percussion and Celesta.
