Vibrato is a musical effect, produced in singing and on musical instruments by a regular pulsating change of pitch, and is used to add expression and vocal-like qualities to instrumental music. Pitch represents the perceived Fundamental frequency of a sound Vibrato can be characterised by the amount of pitch variation ("depth of vibrato") and speed with which the pitch is varied ("speed of vibrato").

Instrumental vibrato

The extent of the variation in pitch in instrumental vibrato is usually decided by the performer, but does not usually exceed a semitone either way from the note itself. A semitone, also called a half step or a half tone, is the smallest Musical interval commonly used in Western tonal music and it is considered the Many string players vary the pitch from below, only up to the nominal note and not above it. The effect is intended to add warmth to a note, and in the case of bowed strings, adds a shimmer to the sound, as the sound pattern emitted by a well-made instrument virtually "points" in different directions with slight variations in pitch. A string instrument (or stringed instrument) is a Musical instrument that produces Sound by means of Vibrating strings In the Hornbostel-Sachs This effect interacts with the room acoustics to add interest to the sound, in much the same way as an acoustic guitarist may swing the box around on a final sustain, or the rotating baffle of a Leslie speaker will spin the sound around the room. The Leslie speaker is a specially constructed amplifier/ Loudspeaker used to create special audio effects utilizing the Doppler effect.

Not all instruments can produce vibrato, as some have fixed pitches which can not be varied by sufficiently small degrees. Most percussion instruments are examples of this, such as the piano. The piano is a Musical instrument played by means of a keyboard that produces sound by striking steel strings with Felt covered hammers Some types of organ however, can produce the effect by altering the pressure of the air passing through the pipes, or by various mechanical devices (see the Hammond or Wurlitzer Organs for example). The organ (from Greek όργανον – organon "organ instrument tool" is a Keyboard instrument of one or more divisions each The Hammond organ is an electric organ which was invented by Laurens Hammond in 1934 and manufactured by the Hammond Organ Company The Rudolph Wurlitzer Company, usually referred to simply as Wurlitzer, is an American company formerly a producer of stringed instruments woodwind brass instruments The clavichord, though technically a fixed-pitch keyboard instrument, is capable of producing a type of vibrato known as Bebung by varying the pressure on the key as the note sounds. The clavichord is a European stringed Keyboard instrument known from the late Medieval, through the Renaissance, Baroque and Classical Bebung may also refer to a musical composition by Michael Jarrell.

The method of producing vibrato on other instruments varies. On string instruments, for example, the finger used to stop the string can be wobbled on the fingerboard, or actually moved up and down the string for a wider vibrato. A string instrument (or stringed instrument) is a Musical instrument that produces Sound by means of Vibrating strings In the Hornbostel-Sachs To create vibrato on flutes, players usually modulate the air flow through the instrument using the diaphragm. On reed woodwinds such as clarinets and saxophones, players tend to create vibrato by repeatedly moving their jaw up and down slightly. Brass instrument players produce a vibrato by gently shaking the horn which varies the pressure of the mouthpiece against the lip. A brass instrument is a Musical instrument whose tone is produced by vibration of the lips as the player blows into a tubular Resonator. Alternatively, the embouchure can be rapidly altered, essentially repeatedly "bending" the note. The embouchure is the use of facial muscles and the shaping of the lips to the Mouthpiece of a Wind instrument.

The guqin, a Chinese bridgeless zither, has documents describing over 25 different types of vibrato that can be executed. The (simplified/traditional 古琴; Pinyin: gǔqín Most peculiar is the vibrato ting yin (literally "still vibrato"); ancient manuals state that the finger on the left hand that is pressing the string should only move or rock ever so slightly so as to alter the pitch minutely, and some manuals say that the finger should not move at all but let the pulse of the finger do the vibrato.

Some instruments can only be played with constant, mechanical vibrato (or none at all), notably the vibraphone and the Leslie speaker used by many electric organists. The vibraphone, sometimes called the vibraharp or simply the vibes, is a Musical instrument in the mallet subfamily of the percussion family The Leslie speaker is a specially constructed amplifier/ Loudspeaker used to create special audio effects utilizing the Doppler effect. Vibrato on the theremin, which is a continuously variable-pitch instrument with no "stops", can range from delicate to extravagant, and often serves to mask the small pitch adjustments that instrument requires.

In pop music the effect is sometimes heard on the guitar and some, but not all, singers use it (in some pop ballads, the vibrato can be so wide as to be a pronounced wobble). Pop music as a genre features a noticeable rhythmic element catchy melodies and hooks, a mainstream style and conventional structure The guitar is a Musical instrument with ancient roots that is used in a wide variety of musical styles The use of vibrato in some folk music is rare, or at least less pronounced than in other forms of music, although in Eastern European gypsy music, for example, it can be very wide. Folk music can have a number of different meanings including Traditional music: The original meaning of the term "folk music" was synonymous

Wide vibrato, as wide as a whole-tone, is commonly used among electric guitar players and adds a vocal-like expressiveness to the sound. An electric guitar is a type of Guitar that uses pickups to convert the vibration of its steel-cored strings into an electrical current which is made louder

Most jazz players through the 20th century and up to the present day have used vibrato more or less continuously. Jazz is an American Musical art form which originated in the beginning of the 20th century in African American communities in the Southern United States The twentieth century of the Common Era began on From around the 1950s, however, some players in more avant garde styles, many following the example of Miles Davis, began to use it more selectively, playing without vibrato as a rule. The 1950s Decade refers to the years of 1950 to 1959 inclusive Miles Dewey Davis III (May 26 1926 &ndash September 28 1991 was an American Jazz Trumpeter, Bandleader, and Composer. Davis frequently used a mute, which also alters the tone of the instrument. A mute is a device fitted to a Musical instrument to alter the sound produced by affecting the Timbre, reducing the volume or most commonly both

Vibrato is sometimes thought of as an effect added onto the note itself, but in some cases it is so fully a part of the style of the music that it can be very difficult for some performers to play without it. The jazz tenor sax player Coleman Hawkins found he had this difficulty when requested to play a passage both with and without vibrato by the producer of a children's jazz album to demonstrate the difference between the two. Jazz is an American Musical art form which originated in the beginning of the 20th century in African American communities in the Southern United States The saxophone (commonly referred to simply as sax) is a conical- bored transposing Musical instrument considered a member of the Woodwind Coleman Randolph Hawkins ( November 21 1904 - May 19 1969) Nicknamed "Hawk" and sometimes "Bean" was a prominent Despite his otherwise exemplary technique, he was unable to play without vibrato. A symphony saxophonist was brought in to play the part.

Many classical musicians, especially singers and string players, have a similar problem. A string instrument (or stringed instrument) is a Musical instrument that produces Sound by means of Vibrating strings In the Hornbostel-Sachs The violinist and teacher Leopold Auer, writing in his book Violin Playing as I Teach It (1920), advised violinists to practice playing completely without vibrato, and to stop playing for a few minutes as soon as they noticed themselves playing with vibrato in order for them to gain complete control over their technique. Leopold Auer (In Hungarian Auer Lipót) ( June 7, 1845 – July 15, 1930) was a Hungarian Violinist, teacher

Vibrato in classical music

The use of vibrato in classical music is a matter of some dispute. For much of the 20th century it was used almost continuously in the performance of pieces from all eras from the Baroque onwards, especially by singers and string players. The twentieth century of the Common Era began on Baroque music describes an era and a set of styles of European classical music which were in widespread use between approximately 1600 and 1750. A drastic change in approach cannot be understood wholly without regarding the rise of notionally historically accurate ("period") performance from the 1970s onwards. However, there is no actual proof that singers performed without vibrato in the baroque era.

Vocal music of the renaissance is almost never sung with vibrato as a rule, and it seems unlikely it ever was. Renaissance music is European music written during the Renaissance, approximately 1400 - 1600 There are only a few texts from the period on vocal production, but they all condemn the use of vibrato.

Leopold Mozart's Versuch einer gründlichen Violinschule (1756) provides an indication of the state of vibrato in string playing at the end of the baroque period. Johann Georg Leopold Mozart ( November 14, 1719 &ndash May 28, 1787) was a composer conductor teacher and violinist Versuch einer gründlichen Violinschule (English A Treatise on the Fundamental Principles of Violin Playing) is a textbook for instruction in the Violin In it, he concedes that "there are performers who tremble consistently on each note as if they had the permanent fever", but condemns the practice, suggesting instead that vibrato should be used only on sustained notes and at the ends of phrases. This however, does not give anything more than an indication of Mozart's own personal taste, based on the fact that he was an educated late Rococo/Classical composer. Rococo is a style of 18th century French art and Interior design. There is no proof, as audio recordings were not around for more than 150 years, that string players in Europe did not use vibrato.

In wind playing too, it seems that vibrato in music up to the 19th century was seen as an ornament to be used selectively. In Music, ornaments are musical flourishes that are not necessary to carry the overall line of the melody (or harmony but serve instead to decorate or "ornament" Martin Agricola writing in his Musica instrumentalis deudch (1529) writes of vibrato in this way. See Agricola for several other people of the same name Martin Agricola ( January 6, 1486 &ndash June 10, Occasionally, composers up to the baroque period indicated vibrato with a wavy line in the sheet music, which strongly suggests it was not desired for the rest of the piece. Sheet music is a hand-written or printed form of Musical notation; like its analogs -- books pamphlets etc

Music by late Romantic composers such as Richard Wagner and Johannes Brahms is now played with a fairly continuous vibrato. Romantic Music is a Musicological term referring to a particular period theory compositional practice and canon in European music history from about 1815 to 1910 Johannes Brahms ( pronounced ˈbʁaːms (May 7 1833 &ndash April 3 1897 was a German Composer However, some musicians specialising in historically informed performances such as the conductor Roger Norrington argue that it is unlikely that Brahms, Wagner, and their contemporaries, would have expected it to be played in this way. Sir Roger Arthur Carver Norrington, CBE (born March 16, 1934) is a British conductor. This is a somewhat controversial view, although Arnold Schoenberg, a considerably later composer, seems to have disliked vibrato as well, likening it to the bleating of a goat. Arnold Schoenberg ( pronounced ˈʃøːnbɛrk (13 September 1874 &ndash 13 July 1951 was an Austrian and later American Composer, associated with Norrington, who is not a string player, is unaware of the fact that continuous vibrato on fast notes is impossible anyway. The curious idea that continuous vibrato was invented by Fritz Kreisler and some of his colleagues seems to be caused by the development of sound recordings which left some people with the impression that vibrato appeared but in the 20th century. Fritz Kreisler ( February 2, 1875 &ndash January 29, 1962) was an Austria -born American Violinist and However the sources unanimously prove that Viennese early 19th century string players like Franz Clement and Joseph Mayseder were noted for their tasteful use of vibrato. Franz Joseph Clement (1780–1842 was an Austrian violinist pianist composer conductor of Vienna's Theater an der Wien and friend of Ludwig van Beethoven. These musicians (and the two Hellmesbergers) represent the school that Fritz Kreisler actually based his stylistic approach on.

The growth of vibrato in 20th century orchestral playing that has allegedly been traced by Norrington by studying early recordings, is not supported by actual samples. An orchestra is an instrumental ensemble, usually fairly large with string brass woodwind sections and possibly a percussion section as well Norrington claims that vibrato in the earliest recordings is used only selectively, as an expressive device; the Berlin Philharmonic Orchestra were not recorded using vibrato comparable to modern vibrato until 1935, and the Vienna Philharmonic Orchestra not until 1940. The Berlin Philharmonic (in German: Die Berliner Philharmoniker) is an Orchestra based in Berlin, Germany. The Vienna Philharmonic (in German: die Wiener Philharmoniker) is an Orchestra in Austria, regularly considered one of the finest in the French orchestras seem to have played with continuous vibrato somewhat earlier, from the 1920s.

It should be stressed in this connection that the sonic limitations of older recordings, particularly with respect to overtones and high frequency information, make an uncontroversial assessment of earlier playing techniques very difficult. In addition, a distinction needs to be made between the kind of vibrato used by a solo player, and the sectional vibrato of an entire string ensemble, which can't be heard as a uniform quantity as such. Rather, it manifests itself in terms of the the warmth and amplitude of the sound produced, as opposed to a perceptible wavering of pitch. The fact that as early as the 1880s composers such as Richard Strauss (in his tone poems "Don Juan" and "Death and Transfiguration") as well as Camille Saint-Saëns (Symphony No. Charles-Camille Saint-Saëns (/ʃaʁl kamij sɛ̃sɑ̃s/ (9 October 1835 &ndash 16 December 1921 was a French Composer, Organist, conductor, and 3 "Organ") asked string players to perform certain passages "without expression" or "without nuance" strongly suggests the general use of vibrato within the orchestra as a matter of course.

Despite this, the use of indiscriminate vibrato in late Romantic music goes largely uncontested (although performances of Beethoven with limited vibrato are now not uncommon). Ludwig van Beethoven ( English ˈlʊdvɪg væn ˈbeɪtoʊvən, 16 December 1770 &ndash 26 March 1827 was a German Composer and Pianist. Many people take the view that even though it may not be what the composer envisioned, vibrato adds an emotional depth which improves the sound of the music. Others feel that the leaner sound of vibratoless playing is preferable.

In 20th century classical music, written at a time when the use of vibrato was widespread, there is sometimes a specific instruction not to use it (in some of the string quartets of Béla Bartók for example). At the turn of the 20th century classical music was characteristically late Romantic in style while at the same time the Impressionist movement spearheaded by Claude Debussy A string quartet is a Musical ensemble of four String instruments &mdash usually two Violins a Viola and Cello &mdash or a piece Béla Viktor János Bartók (March 25 1881&ndashSeptember 26 1945 was a Hungarian Composer and Pianist, considered to be one of the greatest Furthermore, some modern classical composers, especially minimalist composers, are against the use of vibrato at all times. Minimalism describes movements in various forms of art and design especially Visual art and music, where the work is stripped down to its most fundamental features In the 21st century some orchestras are now playing with noticeably less vibrato. The 21st century is the current century of the Christian Era or Common Era in accordance with the Gregorian calendar.

Vibrato and tremolo

The terms vibrato and tremolo are sometimes used interchangeably or inappropriately, although the strict definitions of each describe them as separate effects: vibrato is a periodic variation in the pitch (frequency) of a musical note, whereas tremolo usually refers to periodic variations in the volume (amplitude) of a musical note. Tremolo, or tremolando, is a Musical term with several meanings A regular and repetitive variation in Amplitude for the duration In practice, it is difficult for a singer or musical instrument player to achieve a pure vibrato or tremolo (where only the pitch or only the volume is varied), and variations in both pitch and volume will often be achieved at the same time. Electronic manipulation or generation of signals makes it easier to achieve or demonstrate pure tremolo and/or vibrato.

There are some instances where one of the terms (vibrato, tremolo) is used to describe the effect normally associated with the other term. For example, vibrato is sometimes referred to as tremolo, notably in the context of a tremolo arm of an electric guitar, which produces variations of pitch. A tremolo arm or tremolo bar (also called a "whammy bar" or "wang bar" is a lever attached to the bridge and/or the Tailpiece of An electric guitar is a type of Guitar that uses pickups to convert the vibration of its steel-cored strings into an electrical current which is made louder Pitch represents the perceived Fundamental frequency of a sound Conversely, the so-called vibrato unit built in to many guitar amplifiers produces what is known as tremolo in all other contexts. A vibrato unit is an Effects unit used to modify the sound of an Electric guitar by producing a regular variation in the Amplitude (volume of the sound A guitar amplifier is an Electronic amplifier designed for use with an electric or electronic Musical instrument, such as an Electric guitar.
