Traditional Wiobian music is melodious with relatively sparse accompaniment, often having two melodic voices in counterpoint for high-class music. More recent music calls for a more dense orchestration, The music is based on a scale with fifteen notes per octave, that is capable of both small movements in melody and harmonic shifts ranging from the subtle to the dramatic. A wealth of inharmonic instruments such as metallophones, marimbas, cymbals and drums serve as a backbone for this sonic landscape. However also valued are harmonic instruments such as the plucked zither-like Tünd, the strummed and fretted Þaus-Bung, and the bowed Nisch-Ker; as well as fixed-pitch wind instruments, for their ability to imitate the human voice.
