12.2 String Instrument Techniques

String instruments offer a rich palette of techniques for composers. From bowing to pizzicato, these methods create diverse sounds and textures. Understanding these techniques allows composers to craft expressive and dynamic music for strings.

Exploring harmonics, glissando, and scordatura tuning expands the sonic possibilities even further. Multiple stops and vibrato add depth and emotion to string compositions. Mastering these techniques opens up a world of creative potential for string writing.

• Bowing techniques involve moving the bow across the strings to produce sound
• Detaché is a separate bow stroke for each note with no break between notes
• Legato connects several notes in a single bow stroke to create a smooth, connected sound
• Staccato uses short, crisp bow strokes to produce detached notes (spiccato, ricochet)

Tremolo and Col Legno

• Tremolo rapidly moves the bow back and forth on a single note to create a shimmering, trembling effect
• Measured tremolo alternates between two or more notes rapidly in a single bow stroke
• Col legno uses the wood of the bow to strike the strings, producing a percussive, tapping sound
• Col legno tratto involves drawing the wood of the bow across the strings for a rough, crunchy timbre

Sul Ponticello and Sul Tasto

• Sul ponticello plays near the bridge to create a thin, metallic, intense sound
• Ponticello can add an eerie or unsettling tone color to a passage
• Sul tasto bows over the fingerboard to produce a soft, flute-like, ethereal timbre
• Tasto works well for delicate, intimate passages or to create a distant, muted effect

Pizzicato and Extended Techniques

Pizzicato Techniques

• Pizzicato plucks the strings with the fingers instead of using the bow
• Snap pizzicato forcefully plucks the string so it snaps back against the fingerboard for a sharp, percussive attack
• Left-hand pizzicato plucks the strings with the left hand while the right hand bows or plucks other strings simultaneously
• Pizzicato can add rhythmic interest, punctuation, or a lighter texture to a passage (Debussy's String Quartet)

Harmonics and Glissando

• Harmonics lightly touch the string at specific nodal points to produce high, whistling overtones
• Natural harmonics use open strings while artificial harmonics involve stopped notes
• Glissando slides between two notes by moving the left hand finger along the string
• Glissando can create a dramatic, expressive effect or imitate sounds like sirens or wind (Ravel's Tzigane)

Scordatura Tuning

• Scordatura involves retuning one or more strings to different pitches than standard tuning
• Alternate tunings expand the range of available pitches and allow for unconventional chord voicings or sonorities
• Scordatura was common in Baroque music but can also create unique timbres in modern compositions (Ligeti's Sonata for Solo Viola)

Multiple Stops and Vibrato

Double Stops and Chords

• Double stops play two notes simultaneously on adjacent strings
• Triple and quadruple stops involve three or four notes at once to create chordal textures
• Chords can be rolled or arpeggiated by playing the notes in quick succession instead of simultaneously
• Multiple stops add harmony and depth to a melodic line (Bach's Chaconne for solo violin)

Vibrato Techniques

• Vibrato oscillates the pitch up and down slightly by rocking the left hand finger on the string
• Vibrato speed, width, and intensity can vary to create different expressive effects
• Arm vibrato uses the entire forearm for a wider, more powerful vibrato while finger vibrato isolates the motion to the fingers for more subtle inflections
• Continuous vibrato occurs on every note while selective vibrato adds vibrato to specific notes for emphasis (Elgar's Cello Concerto)

Portamento Sliding

• Portamento connects two notes by audibly sliding between them on the same string
• Sliding can occur with or without fingered notes in between the start and end pitches
• Portamento creates a vocal, singing quality and can heighten the emotional intensity of a melody
• Tasteful portamento was common in Romantic music but became less fashionable in the 20th century (Tchaikovsky's Violin Concerto)
