Ghanaian Gyil Scale Tuning - Woma pentatonic scale

My experience teaching enriches and enhances my musical pursuits. As a pianist first and mallet player second, I come from two traditions of training, jazz and classical; technique and improvisation.

My experience studying music and Ghanaian Xylophone, aka Gyil, in Ghana enhanced my studies by removing me from a familiar instrument, music and culture tradition, tonality, and scale. My Gyil has 14 wooden bars woven together by string, twine, and goat skin; amplified by gourds tuned to each prepared tuned bar.

Although some Gyils are tuned to a western pentatonic scale, most Gyils are tuned to the village master xylophonist's instrument. My gyil is tuned to master xylophonist Bernard Woma's scale. I like to call it the Woma pentatonic scale.

Here is the original tuning of the Woma pentatonic scale, as notes per bar from treble to bass:

  • C# +40 cents
  • B +20 cents
  • A -23 cents
  • F# +35-40 cents
  • E +15 cents
  • D 0 cents
  • C -35 cents
  • A +20-23 cents
  • G -15/20 cents
  • E +50 cents (or F -50 cents)
  • D# -2 cents
  • B +25 cents
  • A -2 cents
  • G -40 cents (almost Gb)

The music is a collaboration with myself on Gyil (with the Woma Scale) and Terry Dame (of Electric Gamelan Junkyard) on her hand-tuned hand-built Gb pentatonic Clayrimba:

Prof. Anku's Time Cycle Theory

Professor Willie Anku is a theorist/ethnomusicologist who focuses on rhythmic theory and travels giving numerous international conferences. This is from his course I took at the University of Ghana-Legon, and here are some examples of notated rhythms he discusses.

A focus of his themes include categorizing rhythms within mathmetical frames and notes how different groups of people, i.e. Yoruba, Bembe, and Ewe, perceive the "1" or "western downbeat". He describes African music theoretically within cyclicality, time and circles. Here is a photo of the time cycle example below...

Here is a link to his full dissertation online.
