meter

9

a group of beats

a measure, or bar

10

music with groups of 2 or 4 beats

duple meter

11

a note that falls before the downbeat of the first measure

pickup, or anacrusis

12

What THREE elements of notation indicate the duration of a note?

the note head, the flags on the stem, and dots

13

How many numbers do time signatures contain?

2

14

what does the top number of a time signature represent

the number of beats in a measure

15

what does the bottom number of a time signiture represent?

how long one beat is

16

compound meter

17

measures with different meters occurring in succession

mixed meter

18

two or more meters occurring simultaneously

polymeter

19

emphasizing notes that fall on weak beats or in between beats

syncopation

20

two or more conflicting rhythmic patterns occurring simultaneously

polyrhythm

21

two or more tones sounding simultaneously

harmony

22

23

3 or more

how many notes must there be in a chord

24

30

WHAT IS THE HIGHEST NOTE OF A TIRAD KNOWN AS??????????????????????????

the fifth

31

Under what circumstance can the human ear not hear beats?

Beats cannot be detected by the human ear if they become too fast. If two interfering pitches are far apart in frequency, there will be too many beats per second for the ear to perceive them.

32

What scientist extensively studied the frequencies of interfering waves and the beats they produce?

Hermann von Helmholtz

33

According to Helmholtz, which three ratios between frequencies and corresponding intervals create the "smoothest" sounds?

1:1 (two notes of the same pitch), 1:2 (an octave(, 2:3 (a fifth)

34

What is the difference between consonance and dissonance?

Consonance occurs when interacting pitches and their overtones are complementary so do not produce audible beats; dissonance is when overtones clash with one another and create beats.

35

In addition to harmonics and beats, what quality of a n instrument affects its timbre?

The material of which the instrument is constructed affects its timbre.

36

When a material is forced into vibrating at one of its naturally occurring frequencies, what do we call this response?

resonance

37

what is polyphone

polyphonic music inclues two or more separate melodies occurring simultaneously

38

what term is used to describe the texture of music that has a single melody accompanied by music hat is written in the same key as the primary melody

both feauture extensive polyphony and melodic repetition

48

ethnomusicology
