The Twentieth Century
Twentieth Century Music
• The Common Practice Period is now
over.
• Composers (and listeners) must now
find something other than key to
organize their music.
• The “Organization of Sound in Time”
Musical style of the Twentieth
Century.
• Harmony - much more dissonant, now
that we have left Common Practice
• Melody - angular, disjunct, harder to
discern - maybe not primary importance
Musical style of the Twentieth
Century.
Duration - rhythm is the feature that has been
the most changed by 20th century music
Dynamics - volume changes are sometimes the
only constant in the form!
Timbre - many new sounds are created. Most
notably: traditional instruments used in nontraditional ways
Musical style of the Twentieth
Century.
Form - very often, the forms in use during
the 20th century mirror those of earlier
times. However, new forms are also
being created.
Arnold Schoenberg
• 1874-1951
• Following the German tradition of
weakening harmony, polyphonic
texture.
• Weakened tonality by creating the 12tone Serialism method of composition.
• He and his followers are called the
“Second Viennese School”.
Serialism
• 12-tone music (dodecaphonic serialism)
• More rational control of the finished
product
• All 12 pitches are used once, no
repeats, no omissions.
• All 12-tone music is atonal, but not all
atonal music is 12-tone.

Commerical vs Art Music
• Split that occurs for the first time in the
20th century
• Commercial music - music created
primarily with profit as its driving force.
• Art music - music that is not created
primarily for profit.
Modern vs traditional
• Modern - serial, atonal, musique
concrete, etc.
• Traditional - Neoclassical. Composers
follow forms from previous periods.
Sonata allegro form, sonata cycle,
fugue, etc.
Tonal vs atonal
• Some 20th century art music is still
written with a heavy emphasis and
awareness of key. Key relationships
are still built and explored.
• NOT ALL 20th CENTURY MUSIC IS
ATONAL!!
More control vs less control
• More rational control over the final
composition. Serialism - the pitches are
already determined before the
composition is started.
• Less rational control - Indeterminacy.
The work is different with each
performance.
Indeterminacy
• Something about the work is left to
chance
• Aleatoric music “Alea” means “roll of the
dice”
• “In C” by Terry Riley
• Unanswered Question by Charles Ives
John Cage (1912-1992)
