1. Definitions of the elements of rhythmic organization.
2. Perception of Tempo and commonly used terms.
3. Mapping out meter (time signatures): the perception of Simple and
Compound Time.
4. How these elements interact in music.
We perceive the organization of time in music in terms of three fundamental
elements,
Pulse
,
Tempo
, and
Meter
. Use prompts to assist you in understanding these
elements:
•
Pulse
—“beat”: the background “heartbeat” of a piece of music.
•
Tempo
—“rate”: the relatively fast or slow speed at which we perceive
the
pulse
in a piece of music.
•
Meter
—“ratio”: how durational values are assigned to represent the
pulse
are organized in discrete segments in a piece of music.
Pulse and Tempo
Pulse
4
, or
beat
, is the regularly recurring underlying pulsation that we perceive that
compels music to progress through time. Pulse makes us react
kinesthetically
to
music: in other words, it compels motion. We tap our feet, we dance, we march, or
we may just “feel” the pulse internally.
In a piece of music, some durational value is assigned to be the pulse. All other
durations are proportionally related to that fundamental background pulse.
Tempo
5
(Latin:
tempus
-“time”) is the rate (or relative speed) at which the pulse
flows through time. This is determined by numerous methods:
1. A metronome marking: for example, MM=120 means the pulse
progresses at 120 beats per minute (two beats per second). Often, in
practice, the background durational value will be drawn and assigned a
4. Pulse (or beat) is the regularly
recurring background
pulsation in music.
5. Tempo is the rate at which we
perceive the pulse in time. This
is indicated by metronome
markings, pulse value
markings and terms.
