Cello technique

Vibrato is an expressive technique that is imitative of the voice in the wavering of the pitch up and down.[3] It is not created by an upper arm motion; rather, it is more of forearm motion. The fixed point of contact of the fingertip on the string absorbs this motion by rocking back and forth, with the thumb typically aligned with the middle finger. This change in the attitude of the fingertip to the string varies the pitch. The use of vibrato is also very personal, some may prefer doing it faster while others may prefer doing it slower. Since vibrato is usually considered a key expressive device, a well-developed vibrato technique is an essential element of a modern cellist's skill.

Harmonics played on the cello fall into two classes; natural and artificial.

Natural harmonics are produced by lightly touching (but not depressing) the string with the finger at certain places, and then bowing (or, rarely, plucking) the string. For example, the halfway point of the string will produce a harmonic that is one octave above the unfingered (open) string. Natural harmonics only produce notes that are part of the harmonic series on a particular string.

Artificial harmonics (also called false harmonics or stopped harmonics), in which the player depresses the string fully with one finger while touching the same string lightly with another finger, can produce any note above middle C. They usually appear with the touching note a perfect fourth above the stopped note, which produces a sound two octaves above the stopped note, although other intervals are available.

Glissando (Italian for "sliding") is an effect played by sliding the finger up or down the fingerboard without releasing the string. This causes the pitch to rise and fall smoothly, without separate, discernible steps.

Legato is a technique that requires notes to be bowed in a connected manner with no stoppage of sound between each note. It can be accomplished through détaché, by playing each note on a separate bow smoothly, with no breaks or accents between bow changes. It can also be accomplished by slurring,[4] or playing multiple successive notes in one bow, which is indicated in the music by a slur (curved line) marking above or below – depending on their position on the staff – the notes of the passage that is to be played legato.

In staccato, the player moves the bow a small distance and stops it on the string, making a short sound, the rest of the written duration being taken up by silence. In some instances, the note marked staccato is to be played at half its value, with the remaining half being a rest. In other words, a quarter note would become an eighth note with an eighth rest.[5] It is noted by writing a small dot above or below a note depending on its position on the staff.

In a fast tempo, it becomes difficult to use the bow to draw the sound out of the string for every note and becomes necessary to instead strike the string with the bow hair while still retaining some horizontal motion with the bow in order to play each note clearly. To play spiccato, the bow must be controlled with the wrist and fingers rather than with the whole arm as is the case when playing legato. As a result, the bow bounces off the string to produce a crisp, percussive sound, making each note audible even in fast-tempo passages.

Sautillé is a technique used for bowing notes in an upbeat tempo that is not quite fast enough to require spiccato. When tempi get too fast for controlled détaché, it becomes necessary for the bow to be bounced slightly off the string with the wrist in a manner similar to spiccato. However, when tempi are not fast enough for completely separated, crisp-sounding spiccato, notes remain slightly connected to create a brushing or scrubbing sound that results from the sautillé stroke.

Sul tasto

Sul ponticello ("on the bridge") refers to bowing closer to the bridge, while sul tasto ("on the fingerboard") calls for bowing nearer the end of the fingerboard. (While reading music, "tasto" can also mean to play with the bow in normal position when having been playing "ponticello") Ponticello calls for more bow weight and slower bow speed, and produces a "harder" sound, with strong overtone content. Sul tasto, in extreme cases called "flautando," produces a more flute-like sound, with more emphasis on the fundamental frequency of the note, and softer overtones.

A player using the col legno technique rubs the strings with the wood of the bow rather than the hair. There are two forms, col legno battuto and col legno tratto. Col legno battuto is performed as a percussive technique with no sustaining of the sound. The much less common alternative is col legno tratto, wherein the wood is drawn across the string as the hair is in a normal bow stroke.

In music pieces, con sord means "with mute" in Italian, and senza sord means "without mute". The mute is a device that is typically made of rubber, and serves to dampen the vibrations on string instruments. On the cello, it can be clipped on the bridge when needed, and can be taken off and attached to the strings below the bridge when not in use.[6]

In pizzicato playing, the string is plucked directly with the fingers or thumb rather than being played with the bow. Pizzicato is often abbreviated as "Pizz.". Position of the hand is slightly over the finger board and away from the bridge. Usually this is done with the right hand, while the bow is held away from the strings by the rest of the hand or (for extended passages) set down. A single string can be played pizzicato, or double, triple, or quadruple stops can be played. Occasionally, a player must bow one string with the right hand and simultaneously pluck another with the left, or even possibly strum with both hands at the same time. This is marked by a "+" above the note. Strumming of chords is also possible, in guitar fashion.

Double stops involve the playing of two notes at the same time. Two strings are fingered simultaneously, and the bow is drawn so as to sound them both at once. Triple and quadruple stops may also be played (in a "broken" fashion), but are difficult to sustain because of the change in slope of the bridge. To extend the technique in this area, Frances-Marie Uitti has invented a two-bow system: one bow plays above the strings and one below, allowing for sustained triple and quadruple stops. However, this technique is very rarely seen or used.

The cello is famous as its melodic, deep timbre. It is one of the most important instruments in symphony orchestra, chamber music, and even solo aspect. Different players in different countries have their own playing style. Usually the way cellists interpret the sound, and even how cellists use their fingerings, are influenced by their own music culture in their own countries.

The French School had a centuries-long impact, which continues today. French playing is often thought of in terms of refinement, finesse, and elegance. However, during the 18th Century in Northern Europe, the cello was still considered a lowly and rudimentary instrument compared to the viola da gamba. The French cello school evolved due to the exquisite playing of Martin Berteau (circa 1700–71). Despite maintaining the underhand bow-hold of the gamba, his sweet tone and depth of expression greatly influenced his students, Jean Pierre Duport, Tillière, and Jean Baptiste Cupis. Berteau developed an effortless fingering system, incorporating the use of the thumb, and introducing the use of both natural and artificial harmonics, which was quite unusual for the cello at the time. Cello fingering, he thought, ought to emulate violin playing where each finger plays a half step or semitone.[7]

There were originally two factions of styles in the German School of cello playing: those who followed Bernhard Romberg (1767–1841) in Germany and Friedrich Dotzauer (1783–1860) in Bonn. Bernhard Romberg, an outstanding performer, is responsible for simplifying cello notation. At the time, composers like Boccherini sometimes wrote cello parts in five different clefs. Beethoven and Mozart, when they wrote for cello in the treble clef, penned the music an octave higher than it was to sound. Romberg simplified notation, limiting cello music to three clefs—the bass, tenor, and treble clef (sounding where it was written). Romberg also introduced a longer fingerboard, with a longer neck on the instrument, allowing cellists to venture into higher positions by using the thumb. He established the notation for the thumb, a circle with a small line (see the diagram) and also modified the C string side of the cello so it could resonate more.[8]

Meanwhile, the Dresden court attracted some of the finest musicians, including Friedrich Dotzauer. Although Dotzauer still played without an endpin, he was the first to advocate holding the bow closer to the frog—the ebony end of the stick. This afforded more control of the right hand and production of sound. He also advocated limiting the use of vibrato. The beauty and purity of tone became paramount.[9]

Russian school developed slightly later than their French and German counterparts, with some influence from the German School. The first notable person to organize his style of playing was cellist Karl Davydov. He received instruction from Friedrich Grützmacher in Leipzig, giving him a strong base in which he further developed his technique. While German schools put more emphasis on the technique of the left hand, Davydov also contributed to the bow technique. He introduced a looser bow hold, and especially a relaxed wrist where the index finger was used to control the pressure.[10]
