Vibrational frequencies and tuning of the African mbira

  title={Vibrational frequencies and tuning of the African mbira},
  author={L. E. and McNeila}
The acoustic spectrum of the mbira, a musical instrument from Africa that produces sound by the vibration of cantilevered metal rods, has been measured. It is found that the most prominent overtones present in the spectrum have frequencies that are approximately 5 and 14 times the lowest frequency. A finite-element model of the vibration of the key that takes into account the acoustic radiation efficiency of the various normal modes reveals that the far-field power spectrum is dominated by… Expand

Imperfect fifths pack into musical scales
Cross-cultural data shows musical scales evolved to maximise imperfect fifths.
