| Recent Developments |
- New Timbres
- Unfamiliar sounds produced by conventional instruments
- Flutter-tongue on wind instruments
- String techniques include col legno (playing
with the wood of the bow), harmonics, glissando.
- New instruments, including vibraphone, Ondes Martenot,
and an expansion of the percussion section of the orchestra.
- Edgard Varèse (18831965) considered timbre
more important than melody and harmony.
- Ionisation (1933) for a battery of conventional
percussion instruments plus chains, anvils, and sirens
- Blocks and masses of sound are the basis for form.
- Déserts (1954) and Poème Électronique
(1958) use electronic sounds (see Chapter 22).
- Electronic Resources
- Musique concrète of the late 1940s manipulated
recorded sounds that were then combined on tape.
- Sounds generated by electronic instruments, such as Stockhausen's
Gesang der Jünglinge (Song of the Youths, 1956),
used both musique concrète and electronic sounds.
- New technology
- By the 1980s electronic keyboards combined with computers
eliminated the need for tape splicing in the studio.
- Computers allowed the composer to control all aspects
of the composition: pitch, timbre, dynamics, rhythm.
- MIDI (Musical Instrument Digital Interface) allowed
composers to translate digitally encoded music directly
into an instrument.
- Many works are intended for live performer with computer-generated
music, or for the performer/composer to improvise using
synthesizers.
- Influence of Electronic Music
- Electronic instruments inspired composers to find new timbres
with traditional forces.
- Dispersing sounds throughout a hall by loudspeakers (e.g.,
Varèse's Poème Électronique)
could be accomplished by separating groups of performers.
- The pitch continuum (an unbroken range of sound from the
lowest to the highest audible frequencies, without distinguishing
separate tones of fixed pitch)
- Sprechstimme only approximated pitch, and Varèse's
sirens used a continuum of pitches.
- Krysztof Penderecki (b. 1933) uses the pitch continuum.
- Threnody for the Victims of Hiroshima (1960)
calls for instruments to play without definite pitches.
- Players choose pitches within a range notated by
the composer.
- György Ligeti (b. 1923) Atmosphères
(1961)
- Begins with fifty-six muted strings with woodwinds,
playing all the notes of the chromatic scale simultaneously,
with instruments dropping out to leave smaller groups
- The next section employs two types of tone clusters.
- Indeterminacy
- Leaves at least one element to the performer's discretion
- The degree of freedom is programmed for each composition.
- Composers may give performers a selection of choices.
- In an "open" form, performers may choose
for themselves or have their choices dictated by a device.
- Karlheinz Stockhausen (b. 1928) was influenced by John
Cage (see Chapter 22).
- Klavierstück XI (Piano Piece No. 11, 1956)
notates several short segments of music that are put together
as the player's eyes see them.
- Opus 1970 is for four players and four loudspeakers.
- Players start and stop a prerecorded tape.
- Fragments of music by Beethoven and other composers
("quotations") combine. (For more on quotation,
see Chapter 22.)
- Witold Lutos£awski (19131994) used indeterminacy
selectively.
- He was also influenced by Bartók and serialism.
- Symphony No. 3 (1983) combines individual improvisation
with harmonic blocks in sections (see CHWM, p.
537).
