While beginning violin students often rely on tapes or markers placed on the fingerboard for correct placement of the left-hand fingers, more proficient and experienced players place their fingers on the right spots without such indications but from practice and experience. To attain good
intonation, violin players train their fingers to land in the right places, learning to hear when a pitch is in or out of tune, and cultivating the ability to correct the
pitch rapidly and automatically as they are being played. "Singing" the pitch mentally helps to land in the right spot. (In practice, intonation may be checked by sounding an adjacent open string, and listening for the
interval between the two notes.) Although adjusting to the desired pitch after landing the finger is indeed possible, the amount of adjustment needed may be greatly reduced by training the fingers to fall properly in the first place. The fingers are conventionally numbered 1 (index finger) to 4 (little finger). Especially in instructional editions of violin music, numbers over the notes may indicate which finger to use, with "0" above the note indicating "open" string, or playing on a string without manipulating the pitch using the left hand. The second finger may be either "low" or "high," corresponding to G or G on the E string in first position (no fingers on the string). Similarly, the first finger may reach a half-step down for the F, and the 3rd and 4th fingers reach up for A and C respectively, as shown on the chart of
Bornoff finger patterns on the left. (Pattern number five may be seen to be the same as pattern number three, but a half step lower, or in "half position".) The lower chart on the left shows the arrangement of notes reachable in first position. Left-hand finger placement is a matter of the ears and hand, not the eyes, that is, it has strong
aural and tactile/
kinesthetic components, with visual references being only marginally useful. Also (not shown on this chart), the spacing between note positions becomes closer as the fingers move "up" (in pitch) from the nut. The blue bars on the sides of the chart represent the usual possibilities for beginners' tape placements, at 1st, high 2nd, 3rd (and 4th) fingers, or Bornoff pattern number two. This particular pattern results in an A major scale on the A and E strings, which is a natural start for simple tunes like "Twinkle Twinkle Little Star".
Positions The placement of the left hand on the fingerboard is characterized by "positions". First position, where most beginners start (some methods start in third position) is nearest to the nut, or scroll end, and furthest from the player's face. The lowest note available in this position in standard tuning is an open G; the highest notes in first position are stopped with the fourth finger on the E-string, sounding a B. Thus, in
first position, the first finger placed on the E-string gives an F; from this position, the second finger can play a G or a G, the third finger an A, and - as previously mentioned - the fourth a B. Positioning the first finger so when pressed it gives a G (still on the E-string) is called
second position, from which position all the ascending notes up to C (by the fourth finger) may be played.
Third position is achieved when the first finger presses down on an A, and so on, with
fifth position on one string sounding the same notes as first position on the string above. There is also a "half position" where the first finger sounds a semitone above the open string and the other fingers a tone or semitone below their normal positions, e.g. (on the A string) A-B-C-D. The same notes could be played in first position with the first finger moving from "low first" (A) to B, but this would produce a sliding first finger, which is not always desirable. The upper limit of the violin's range is largely determined by the skill of the player. A skilled player can play more than two octaves on a single string, and four octaves on the instrument as a whole. All except the lowest and highest notes can be played on multiple strings in different positions. That is, the "high" B note referred to above can be played not only by the fourth finger on the E-string in first position, but also by the fourth finger in fifth position on the A-string, in ninth position on the D-string, and thirteenth position on the G-string. Violinists often change positions on the lower strings, sometimes to the consternation of composers and much to the confusion of beginners. This is usually done to handle a musical passage that would otherwise require fast switching (or "crossing") of strings. It is also done to produce a particular
timbre: the same note will sound substantially different depending on which string is used to play it. That "high" B, when played on the E-string (the highest, usually a mono-core metal string) can have a clear, even piercing timbre; the same "high" B played on the A-string or D-string or G-string (usually wrapped strings rather than mono-core) may sound "warmer" or less abrasive. For this reason, violinists often avoid playing a single note on the E-string within a phrase of notes on the A-string, as one E-string note would stand out with a different timbre. Different strings have different tone qualities, because of their different physical composition and their different resonances on the instrument. The choice of timbres on different strings is vital to the musicality of the instrument, and intermediate and advanced players will often deliberately play in a higher position on a lower string for effect. This effect is sometimes indicated by the composer or arranger. The most common indication uses the letter name of the string: for example, if a composer wants a passage that would otherwise be taken on the D-string to be played on the G-string, they write "sul G", "G-Saite", "auf G", "G corde", or "on G" in the part, the first two being the most commonly used notations. Occasionally, numbers or Roman numerals are used, so the example might be written "4. corde" or "IV corde" (as above, with the highest string being No. 1 and the lowest No. 4); the simplest way to indicate which string to play is to write the number (e.g., "IV" or "III") alone.
Open strings A special timbre results from playing a note without touching its string with a finger, thus sounding the lowest note on that string. Such a note is said to be played on an
open string. Open string notes (G, D, A, E) have a very distinct sound resulting from the absence of the damping action of a finger, and from the fact that vibrato (see below) is produced differently from on-fingered notes. Other than low G (which can be played in no other way), open strings are sometimes selected for special effects. One striking effect that employs open strings is
bariolage. This is the repeated alternation of notes played on two or more strings, where one of the notes is usually an open string. This string crossing is often rapid and is best executed with a sinuous movement of the bow arm. Sometimes the same pitch as an open string will be fingered on an adjacent string, so that the alternation is between the same note on two strings, one stopped, one open, giving a rhythmic pulsating effect. Bariolage was a favorite device of
Joseph Haydn, who used it for example in his
string quartet Opus 50 no. 6, and in the
"Farewell" Symphony. It is also prominently featured in the Preludium of Bach's
Partita No.3 in E major for solo violin. Playing an open string simultaneously with a stopped note on an adjacent string produces a
bagpipe-like a drone, often used by composers in imitation of
folk music. Sometimes the two notes are identical (for instance, playing a fingered A on the D string against the open A string), giving a ringing sort of "fiddling" sound.
Double stops and drones Double stopping is when stopped notes are played on two adjacent strings, producing a two-note harmony. This is more difficult than normal single-string playing, as fingers must be accurately placed on two strings simultaneously. Sometimes moving to a higher position is necessary for the left hand to be able to reach both notes at once.
Double stopping is also used to mean playing on three or all four strings at once, although such practices are more properly called
triple or
quadruple stopping. Collectively, double, triple and quadruple stopping is called
multiple stopping. However, triple or quadruple stopping is more commonly just called a chord. Sounding an open string alongside a fingered note is another way to get harmony. While sometimes also called a double stop, it is more properly called a
drone, as the drone note (the open string) may be sustained for a passage of different notes played on the adjacent string.
Vibrato Vibrato is a technique of the left hand and arm in which the pitch of a note varies in a pulsating rhythm. Mechanically, it is achieved by fingertip movements which alter the length of the vibrating string. There are several different styles of vibrato ranging from the use of just the fingers to the use of the wrist or even the whole forearm. By employing these different techniques both the speed and amplitude of vibrato oscillations can be varied for musical effect. Vibrato is often perceived to create a more emotional sound, and it is employed heavily in music of the
Romantic era. The acoustic effect of vibrato has largely to do with adding interest and warmth to the sound, in the form of a shimmer created by the variations in the projection of the strongest sound. A well-made violin virtually points its sound pattern in different directions depending on slight variations in pitch. Violinists oscillate backward, or lower in pitch from the actual note when using vibrato, since
aural perception favors the highest pitch in a varying sound. Vibrato does little if anything to disguise an out-of-tune note. Violin students, especially those of beginner level, are taught to use it only on extended notes and or during points of emotional tension. Vibrato can be difficult to learn and may take a student several months, if not years, to master.
Harmonics Lightly touching the string with a fingertip at a harmonic
node while bowing close to the bridge can create
harmonics. For the harmonics to produce the most consistent tone and volume, the bow needs to be making longer faster strokes. Instead of the normal solid tone a wispy-sounding overtone note of a higher pitch is heard. Each node is at an integer division of the string, for example exactly halfway along the length of the string, or exactly one-third along the length of the string. The pitch produced in these two cases will be an octave higher in the case of halves, and an octave and a fifth higher in the case of the string vibrating in thirds. A responsive instrument will provide numerous possible harmonic nodes along the length of the string. Harmonics are marked in music with a little circle above the note that determines the pitch of the harmonic. There are two types of harmonics:
natural and
artificial (also known as "false harmonics"). Artificial harmonics are more advanced than natural harmonics described above. Stopping a note on one string, for example, first finger "E" on the D string, and having another finger just touching the string a
fourth higher, in this case on the position of the note "A", produces the fourth harmonic of the "E", sounding a tone two octaves above the note that is stopped, in this case, E. Finger placement and pressure, as well as bow speed, pressure, and sounding point are all essential in getting the desired harmonic to sound. The "harmonic finger" can also touch at a major third above the pressed note or a fifth higher. These harmonics are less commonly used because they are more difficult to make sound well. In the case of the major third, the harmonic is higher in the overtone series, and does not speak as readily; in the case of the fifth, the stretch is greater than is comfortable for many violinists. The sounding pitch of the major third harmonic is two octaves and a major third above the lower note, and in the case of the fifth, it is an octave and a fifth above the lower note. Traditional notation of artificial harmonics uses two notes on one stem: the lower note employs a round note-head representing where the string is strongly stopped with the first finger, and the upper note uses an open
diamond note-head representing where the string is lightly touched with the fourth finger. Harmonics are also rarely played in double stops, where both notes are harmonics. Elaborate passages in artificial harmonics can be found in virtuoso violin literature, especially of the 19th and early 20th centuries. ==Right hand and tone color==
