A method for calculating the unblown resonant frequencies of an ‘Oja’ (a traditional Nigerian musical instrument) is developed. Support for the theory is provided by data derived from experimentally measured spectra of typical oja tones. It is also shown that for resonant frequencies below about 2000Hz, the differences between the theoretical and experimental data are in qualitative agreement with the findings of earlier investigators with regard to the effect of a mouth-cavity resonance on the resonant frequencies of a wood-wind instrument.
