This study explores advanced synthesis models for spectral manipulation and non-definitive tonality induction, addressing a gap in psychoacoustics research regarding the interaction of bandpass noise and tonal elements within hierarchical tonality frameworks. Drawing on hierarchical processing, pitch salience, and psychoacoustic perception theories, this research uses intonation and pitch recognition tasks to investigate how trained and untrained listeners interpret spectral modifications and tonal ambiguity; possible opportunities for application in musical composition and performance are examined. The study advances the discourse on tonal hierarchy by incorporating noise-based pitch induction as a compositional tool, with implications for both music theory and synthesis technology.
