Sommaire.

Préface.

Note.

Part one.

I. Introduction : geographical, cultural, and language areas outlined.

II. The music and some preliminary considerations.

Terminology defined : "primitive", "simple", "complex", "high civilization".

Harmony : parallel thirds as precursors of functional harmony; comparison with protoharmony of European gymel and European folk music; chronology of intervals of third, fourth, fifth.

Rythm : misconceptions concerning African rhythm; the African hemiola style and its relationship to the traditional European hemiola; relationship to additive rhythms of Orient; Western offbeat syncopation versus the African hemiola style.

Scale make-up and terminology : "diatonic" as indicating a scale comprising only tones and semitones; "chasmatonic" as indicating a scale comprising one or more intervals grater than a tone; "pentatonic" as a special species of chasmatonic, within the octave span.

Antiphonal and responsorial singing : clarification of terminology.

Names of Instruments : the significance of similar names in different areas.

III. Musical ethnology of Central Africa.

Music for the ceremonial : healing; initiation (puberty circumcision, secret society, royal); birth; marriage; hunting; new year and new moon.

The work song.

Music for entertainement : group participation, professionalism.

Music for litigation : vocal music as a vehicle for criticism and airing of grievances.

The dance : realistic, entrovert versus abstract, introvert.

Speech melody and the "talking" drum.

IV. The music - analysis and discussion.

Melody types (diatonic, chasmatonic, short-lined, long-lined) : one- or two-step nucleus; descending tetrachord; rising pentachord fanfare; hexachord; minor seventh with tritone effect; octave (descending and ascending; zig-zag thirds); supra-octave ladder of thirds; non-tempered intervals.

Rhythm : the African emiola style; horizontal hemiola (close-paced; sectional); vertical hemiola (instrumental, vocal, vocal-instrumental); tempo (rapid gamut).

Polyphony and form : parallelism (thirds, fourths, fifths); overlapping antiphonal and responsorial singing (canon at fifth and at unison; elongated cadence); ostinato and dron-ostinato; contrapuntal movement (drual- or triple-melody type; interjectionvariation type); "hanging chords"; combination of polyphonic devices; raised "leading-tone"; litany form; rondo form; sequence or lai form; development in melody or in overall form.

V. Singing style.

Problem of identifying factors comprising a vocal style : structure of music; voice-production components.

Physio-acoustical terms defined : registration (use of the two groups of muscles, arytenoid and thyroid, contolling the vocal cords); upper register (timbre resulting from the functioning of the arytenoid group of muscles); lower register (timbre resulting from the functioning of the thyroid group of muscles); isolated register (timbre resulting from the functioning of one group of laryngeal muscles without the other); resonance (amplification of sound in atuned cavity, notably the pharynx).

African female singing : combined registration with lower register predominationg; high intensities; lower pitch range; result equals typical stridency of low register at maximum.

African male singing : combined registration with upper register predominating; high intensities; lower pitch range; rsult equals typical hoarse-guttural "tenor" quality of hupper register at maximum.

Gutturalness : especially in men's voices; resulting from upper register at high intensity, from pressure of neck constrictor-muscles on larynx, and from tongue hyoid-muscle pressed towards rear of oral pharynx.

Resonance : non-pharyngeal; mouth resonance (in both men and women).

Absence of vibrato : occasional tremolo.

Emphatic, Outdoor, group style : shouting and screaming; dynamic and timbre accents (point of excessive breathiness, gutturalness, nasality).

Ornaments : not common except in Arab-style singing; different-pitched and same-pitched grace note before the beat; "Scotch-snap", mordent; double-mordent; note-clusters between two tones; double grace-notes before beat.

special effects : yodelling; humming; Sprechstimme; hocket; glissando; whistling; drum duplication of vocal melody.

Syllabic, non-melismatic style.

VI. Conclusion.
Possibility of "musical map" : common, widespread style elements; sporadic elements. Symmetry and Asymmetry in Central African art forms.
