Test #1 Flashcards
Additive Synthesis
creates timbres by adding sine waves
Aerophones
Any instrument that makes sound by causing air to vibrate
Alternating Current
electric charge periodically reverses direction
Amplitude
height of a wave
Analog
non quantized variations; any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. For example, in an analog audio signal, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves.
Attack
Initiation of a sound
Milton Babbit
Associated with the Colombia-Princeton Electronic Music Center
Luciano Berio
Founded Studio di Fonologia in Milan, Italy
Cahill
Founder of the Telharmonium
Channels
different layers of sounds/inputs/outputs in all electronic work
Chordophones
instruments that make sounds via vibrating strings
Cologne Studio
the city in Germany where WDR (Westdeutscher Rundfunk, radio station) was created in 1951 and Elektronishe Musik with Stockhausen and Meyer-Eppler
Colombia University Studio
Ussachevsky in charge and Luening associated
Colombia-Princeton Electronic Music Center
created with a grant from the Rockefeller Foundation and got the RCA Mark II; it came after the Columbia University Studio; Ussachevsky and Luening of Columbia and Babbitt and Sessions from Princeton
Compression
affects volume/dynamics
Cut-off frequency
a boundary in which energy flowing through a system begins to reduce
Decay
end of a sound
Delay
sound played again after a period of time
Depth of Field
front to back portion of the “cube”
Direct Variation
turning the tape around; retrograde
3 Types of Echo
Single channel reflection, dual channel reflection, and head-slap
Elektronishe Musik
Developed at Cologne Studio/WDR
Electrophones
Instruments involving electricity
Envelope
Attack, sustain, and decay
EQ
Balances the highs, mids, and lows
Erase Head
erases content on a reel of magnetic tape
Fader
controls the volume on a mixer
Filter
an electrical circuit that emphasizes or eliminates some frequencies from a signal
Fourier
combined sine waves to make new sounds
Frequency
determines pitch
