Musicians of Akan of Ghana
- must have good and "pleasant" voice m must be strong or "heavy" (to be heard); "thin" voice unacceptable even if sweet
- must have good ear and the ability to concentrate
- must not suffer from "sweet ears,"
i.e., must not be distracted by parts of other performers (singers and instrumentalists)
- must have a knowledgeable command of language; ability to improvise texts;
to fit melodies to new words;
to memorize a large repertoire of songs
- must be expressive; to be able to involve and inspire others
- must have endurance
B. Recruitment
- many groups take active role in recruiting specialists who play vital roles
- Replacement of "official" drummer often seen as major ritual event
- Sometimes a specific family may be responsible for supplying a particular musical tradition
- In Dagomba country the son of every player of an hourglass drummer is expected to become a dancer
- daughter is released from this obligation but must eventually send a son to replace her
- if she has only daughters, one must marry a drummer
- If not hereditary, becoming a specialist is sometimes contingent on a "calling" (i.e., dream or spiritual experience)
C. Training
- Seldom formal or systematic
- Mothers usually inculcate basic music values
- Children rely on ability to imitate
- Some formal apprenticeships, but increasingly rare, as music-making in village is part-time job
Ensemble of balafons, flute and drum
VIII Organization of Instrumental Ensembles
A. Melodic instruments (definite pitch) performing in ensembles:
trumpet (natural, e.g., aluar horns, bungo horns etc.), flute, harp/lute, xylophone
- Example: Trumpet Ensemble (Dan)
- 6 ivory trps (accomp. by 4 drummers)
- lowest and highest produce 2 pitches, others only 1 pitch
- pitches organized in interlocking ostinato or "hocket" arrangement
- sung melodies picked up and "translated"
into trumpet patterns
- Example: Trumpet Ensemble (Senufo, Ivory Coast)
- Wooden cross-blown trumpets in simple interlocking ostinato
- Percussion accomp. provides cross-rhythms
Balafon
- Example: Xylophone Ensemble (Senufo)
- Example: Xylophone Ensemble (Chopi, South Africa)
B. Instruments of indefinite pitch: drums, bells, rattles, struck gourds, stick clappers etc.
- usually with varying sonorities in 4 different "voices" of drums
- lowest pitch usually considered "master drum" which determines patterns of others and sometimes improvises soloistically
- Example: Drums of the Women (Poro, West Africa)
- Example: Percussion Instruments of the Women (Poro)
- Example: Drum rhythm (traveling soloist) (Dan)
- Example: Drum rhythm No. 1 (Watusi, Ruanda)
- Example: Drum rhythm No. 2 (Watusi)
- Example: Drum rhythm with vocal (Yoruba, Nigeria)
- Example: Slit-log Talking Drum (Bambala, Congo)
Djembe
Talking Drums
VIII Melody, Polyphony and Rhythm in Instrumental Music
A. Scales between 4 and 7 notes
- depending on local traditions, instrument makers etc. (no universal pitch standard)
- pentatonic scales of various types frequent
- "hard" pentatonic: C-Eb-F-G-Bb
- "soft" pentatonic: C-D-E-G-A
- "other": e.g., C-D-E-G-Bb (typical of Ba-Mbuti)
- 7 note scales may resemble western "major" scale, but frequently do not
- Some melodies employ half steps in patterns completely unrelated to western manor or minor scales
B. Instrumental melodies may be ornamented variations of songs on which they are based
C. "Original" instrumental melodies often based on sequences of repeated patterns (e.g., music for mbira or xylophone) or melody from which "emerges" a pattern
D. Types of melody in instrumental music (typical contours)
- Mildly undulating, often beginning on low tone, rising, then returning
- Pendulum motion: swinging back and forth between high and low pitches or range
- Melodic contour sometimes based on tonal patterns of spoken language
E. Polyphony in instrumental music
- melody against ostinato
- layered motives (e.g., "hocket-like" distribution of short melodic motives)
- 2 equal parts in counterpoint
- Occasional use of "imitation" in Shona Mbira duets
- "Chords" from musical "fiddle"
F. Rhythmic basis of instrumental music
- Rhythm conceived in terms of abstract patterns or speech patterns (free or metric)
- types of patterns
- divisive: employing equal divisions of larger time units (i.e., subdividing units of time into several equal units)
e.g., a "measure" or "cycle" of 8 beats made up of 4 sub-units of 2 beats:
2+2+2+2
- additive: unequal units of time added together to make up a larger unit of time e.g., a "measure" or "cycle" of 8 beats with sub-units of 3+2+ 3
- Most African music includes some clearly apparent "Time Line," an "externalization" of the basic pulse or pattern against which other parts are measured
- Multilinear rhythms
- usually results from layering of interlocking parts ranging in "graded" levels of complexity
- "Cross-rhythms" (Hemiola?) often results from a combination of some layers which appear to be divisive and some which appear to be additive
IX Melody, Polyphony and Rhythm in Vocal Music
A. Scales similar to instrumental music but more variety and not necessarily equivalent in type, even within a tribe or community
- some vocal music appears to exploit "pitch areas" rather than the more precise pitch types of instrumental music
B. Types of melody in vocal music
- Undulating
- Sharply descending or terraced descent with undulating motion)
- Pendulum motion
C. Polyphony and harmony in vocal music
- songs basically conceived as monophonic may occasionally break into 4ths or 3rds for "decoration" or to "thicken" the tone
- Methodical use of polyphony/harmony in 3rds or 4ths (occas. 5ths) is rare
- use of voices in parallel 3rds or 6ths occasionally found by tribes frequently employing 7-note scales (e.g., Baoule-Kode, Ibo of Nigeria, some tribes in Ghana and the Congo, etc.)
- but even among groups using 7-note scale, the uses of 4ths (and occas. 5ths) is still often preferred or used alternately with thirds (e.g., some groups in Kenya or Tanzania)
- Parallel 4ths (and 5ths) more typical of groups using pentatonic scales (esp. East Africa)
- Parallel motion in 3rds in 3 parts (resulting in "triads") is rare (prior to Western influence)
- parallel motion in other intervals
(e.g., 2nds) found occasionally
- sometimes more complex polyphony resulting from a combination of multiple parts (e.g., layering or "hocket" texture)
D. Organization of vocal music
- melodies are frequently "strophic variations," i.e., the same melodic idea is repeated again and again but usually varied or ornamented in some way
- melodies may have contrasting sections, but patterns are usually simple, e.g., A B A
- Form sometimes consists of a series of solo "declamations" rounded of by recurring refrain
- Call and response interaction
- response to leader phrase(s) may be exact imitation, simplified imitation, or continuation
- occasionally leader and chorus phrase may both change
E. Great tendency for singers to "color" vocal quality or provide variety of vocal timbre during song
- Most traditions emphasize "open" vocal production; some prefer a more restricted tone
- Sometimes songs include "unusual" sonorities, e.g., falsetto, yodeling quality, humming, "growling," tremelo, vibrato, nasalization at phrase endings etc.
