The Ikoro or Ekwe, is a wooden slit drum, a percussion instrument of the idiophone family, which by virtue of its functions and its predominance in the eastern parts of Nigeria with the Igbo’s and plays an important role in the Igbo musical culture and settings. The Ekwe being a drum made of wood has pitches, and produces a very deep rich bass sound which can be heard from a distance and has a sustained reverberation rendering a background beat to music or sound of warning. This paper looks at frequency domain of the sustained reverberation, measuring and analyzing the dynamics responses of the structure upon an excitation, describes the historical and constructional process of the Ekwe, and examines the isomorphism between Ekwe music and mathematics by applying the narrative of mathematical music theory developed by Richard Cohn (Yale). This work explores how the rhythm, meter and pitch of Ekwe music, can be represented through using various techniques such as visualizations and sonifications, by applying Cohn’s beat-class set theory with Andrew Milne’s (WSU) instruments of mathematical music theory, the cyclic graph XronoBeat, and SkiHill apps. These analyses provide a deep understanding of the distinct sound of the Ekwe.
