  • Implementation of melodic morphing based on generative theory of tonal music

    Open AccessMasatoshi Hamanaka, Keiji Hirata et al.ARTICLEJournal of New Music Research2022

    This paper proposes a new morphing method to generate a melody, given two melodies represented by time-span trees obtained from the generative theory of tonal music (GTTM). In this paper, we define a feature structure based on a time-span tree and the distance between two structures. Next, we construct a lattice of subsumption relations among these structures and define three algebraic operations: reduction, meet, and join. First, we conduct thes…

  • "Implementing "A Generative Theory of Tonal Music

    Masatoshi Hamanaka, Keiji Hirata et al.ARTICLEJournal of New Music Research2006Cited by: 4References: 6

    This paper proposes a music analysing system called the automatic time-span tree analyser (ATTA). ATTA derives a time-span tree that assigns a hierarchy of “structural importance” to the notes of a piece of music based on the generative theory of tonal music (GTTM). Although the time-span tree has been applied in music summarization and collaborative music creation systems, these systems use time-span trees manually analysed by experts in musicol…
