Music of Sub-Saharan Africa
General Principles of African Music
Call and Response is one form of interlocking
On the mbira the bass, midrange and high melodies create a polyphonic texture, and a listeners perception of the piece changes depending upon which line you are listening to.
Two players are needed to play separate and complementary parts.
Kushaura to lead, or play the basic piece
Kutsinhira accompanying part (both words are verbs, not nouns)
a. almost the same but played a beat or two behind.
b. completely different accompanying part is composed to interlock with kushaura
Hand clapping, dance movements and vocal melodies can be added. They do not reproduce the beat but each participant adds their own clapped patterns so that they fall inbetween or around the central beats and pitches in the spaces of other peoples parts.
A basic musical value is the ability to add ones own distinctive part to the ensemble while making it blend into whole.
African music is polyphonic and polyrhythmic created by overlapping different participants contributions.
Buzzing sounds are common gourds, bottle caps.
Community participation is valued, so repetition and long performances make it easier to join in
Classical mbira music has a melodic-harmonic cycle (ostinato) or 48 quick beats, divided into four 12 beat cycles. Small variations (formulas and improvised lines) are gradually added to and over the basic ostinato. It is not considered good playing to use overly apparent or dramatic contrasts. Rather one variation is built on the previous and subtly leads into the next cycle. Each variation is repeated several times before changing it.
Multiple layers creates tension and ambiguity listener can hear it many different ways.
Core parts are the foundation. Can be rhythm, basic melodic-harmonic ostinato, bass
Elaboration is the improvised variation clapped patterns, vocal lines, high melodies, bass variation, dancing.
Resources include harmonic, temporal and melodic character of the basic ostinato, a series of stock variations and motifs associated with the piece, certain sung melodies and lines of text.
Length will vary each performance, as will speed, character of development and improvisation pattern.
Often particular "pieces" are associated with specific people, moments or contexts.
