✦ Synopsis

This paper is a sequel to reference [1]. In that paper, the dynamics of the steelpan notes were developed as systems of non-linear mode-localized oscillators. The present paper examines the coupled note-note and note-skirt systems on the steelpan modelled as a plexus of non-linear oscillators interconnected by linear mechanical filters. The tonal qualities of a note depend on the degree of coupling and the closeness in frequency of the excited modes on the interacting subsystems. Modes above the fundamental (the partials) are produced by internal and combination resonances.

By combining the method of multiple scales with the short-time Fourier transform, the vibrational motions of notes on the steelpan have been investigated analytically and experimentally. The motions on this musical instrument display many of the characteristics of non-linear dynamical systems, in pa

This paper is the third in the series on this topic. In the earlier papers, the dynamics of the steelpan notes were developed as systems of non-linear mode-localized oscillators which can show note-note and note-skirt coupling. The tonal qualities of a note depend on the coupling parameters and damp
