Basic Elements of Music Theory Flashcards
Section I of USAD Music Resource Guide terms and definitions
Music
Sound organized in time
Sound
A wave of energy consisting of both amplitude and frequency
440 Hz
Sounds like an A above middle C
Between which cycles per second will the human ear hear a single, sustained pitch?
20 and 20,000 cycles per second
Percussion instruments provide most of these sounds in music
Non-pitched sounds
Ethnomusicologist
The modern term for scholars who study the music of other cultures, or who study multiple cultures comparatively
Curt Sachs and Erich von Hornbostel
Created the four Sachs/Hornbostel classifications for instruments
Chordophones
Have one or more strings, which are plucked, bowed, or struck (violins, harps, guitars, violas, cellos, double bass, lute, etc.)
Aerophones
Brass and wind instruments that feature a vibrating column of air (horns and lutes)
Membranophones
Have a skin or other membrane stretched across some frame; the membrane vibrates when struck (timpani, bass drum, snare, tambourines, etc.)
Idiophones
The body of the instrument itself vibrates when struck (marimba, xylophone, vibraphone, tubular bells, gongs, cymbals, triangle, wood block, etc.)
Electrophones
A later-added fifth category to the Sachs/Hornbostel classifications, which create sound waves using an oscillator and are dependent upon electricity (synthesizers, etc.)
Centuries before Sachs and Hornbostel, Western orchestral instruments were grouped into
Families
Strings
Usually bowed or plucked; correlate closely to chordophones
Brass
Aerophones made of metal, and are sounded by the performer’s buzzing lips (trumpet, trombone, French horn, tuba, flugelhorn, baritone, bugle, etc.)
Woodwinds
Aerophones in which the column of air is moved by breath alone or by one or two vibrating reeds made from wood (flutes, recorders, piccolos, oboes, clarinets, bassoons, saxophones, etc.)
Percussion
Includes membranophones and idiophones, plus some chordophones that are struck rather than bowed or plucked, such as the piano
Theremin
One of the best-known early electronic instruments in which the performer regulates frequency with one hand and amplitude with the other
Musique concrete
Electronically generated sounds and sound produced by live instruments were recorded on tape, where they could be edited, manipulated, and mechanically recombined to form collages of sound that were “performed” via loudspeaker
Where were the first practitioners of musique concreté based?
Paris
What are the basic techniques of tape music?
Looping and splicing
Which four cities had famous postwar centers for electronic music?
Rome, Paris, Cologne and New York City
Pitch
The highness or lowness of a sound, which consists of a steadily oscillating sound wave
What happens when halve the length of a string on a guitar and play it?
The string vibrates twice as fast and plays a pitch that is twice as high
