Vocabulary for a Cross-Cultural Musical Analysis (Ethnomusicological Approach)
Ethnomusicological definition of music: "Music is sound which is organized
in a manner either dictated by or acceptable
to a particular culture and/or one of its populations"
Four characteristics of sound used to describe music:
1) Quality (tone color or timbre)
2) Intensity (softness or loudness)
3) Duration (length)
4) Pitch (highness or lowness)
1) Quality is determined by the sound source, whether instrumental or
vocal.
2) Intensity is the relative softness or loudness of sound. There are
no specific
terms for cross-cultural analysis (although it is possible to quantify this
parameter according to decibel level.)
3) Duration is the temporal aspect of music. The term rhythm is often
used in its
broadest sense to describe all temporal aspects of a composition.
The following terms may be used to describe duration in music:
Pulse One of a series of regular, recurrent, and precisely equivalent beats.
Stress Dynamic intensification of a beat, similar, but not exactly equivalent to-
Accent A beat marked for emphasis in some way.
Meter Measurement of pulses between accents; in some systems, the accents are irregular, or vary in a pattern.
Free rhythm No regular or recurrent pulse.
Parlando-rubato style Rhythms patterned after speech.
Tempo The rate of speed of the piece, or number of beats per minute (often measured by a metronome).
4) Pitch is the highness or lowness of sound. Pitch resources of various
cultures and/orstyles
vary (the intervals, or distance, between pitches differ according to cultural
convention.)
Pitches arranged in uniform order of ascent or descent are called a scale. Pitches
arranged in an order perceived as a unity are called a melody. Melody can be
described by its range (the total number of pitches it encompasses) as well
as by its contour, which may be conjunct (moving by small intervals) or disjunct
(moving in large intervals). The number of pitches in a scale are often described
by (Greek) termspentatonic (a five pitch system), hexatonic (a six
tone system), etc.
Form or structure is the result of the relationships of all characteristics
of sound on many levels within a music.
Forms employing the same, small melodic or rhythmic formula repeatedly can be
termed iterative; a repeated figure can also be called an ostinato. If a section
returns after a digression, the form may be termed rounded or reverting. If
the same melody is repeated with different text, it may be called a strophic
form.
