DESCRIPTION:Title: Tone-Clock Theory and Jazz: A New Framework for Post-Ton
 al Improvisation and Composition\n\nJonathan Lindhorst\, current Jazz Perf
 ormance PhD\, finalist of the 2025–2026 Research Alive Student Prize\n\n 
 \n\nDespite jazz’s openness to diverse influences\, it has resisted twelve
 -tone music in improvised contexts. Over the past 30 years\, a small group
  of improvisers and composers have turned to Tone-Clock Theory (TCT)\, a r
 adical post-tonal system first codified by Dutch composer Peter Schat and 
 later expanded by New Zealand composer Jenny McLeod. TCT maps all of chrom
 aticism through the lens of twelve ‘chromatic tonalities\,’ or ‘Hours\,’ o
 ffering a flexible\, non-prescriptive framework for organizing chromatic m
 aterial. In the mid-1990s\, musicians from New York and Amsterdam\, notabl
 y saxophonist John O’Gallagher\, began adapting TCT to jazz\, connecting i
 t to the improvisational language of late-period John Coltrane and codifyi
 ng their approach in pedagogical materials for improvisers\, influencing a
 n emerging global community of Tone-Clock influenced musicians. In this pr
 esentation\, I outline key features of TCT\, demonstrate its applications 
 in my improvisation and composition\, and argue for its potential as pract
 ical post-tonal framework for jazz.\n\nDescribed as “an imperious presence
  on tenor sax” (Eddie Myer\, Jazzwise)\, Canadian saxophonist\, composer\,
  and researcher Jonathan Lindhorst works between jazz\, free improvisation
 \, and New Music. A D.Mus. candidate at 91˿����Ƶ’s Schulich School of Music\
 , he researches Tone-Clock Theory and early women in jazz\, regularly pres
 ents and teaches on these topics internationally\, and has been published 
 in the Zeitschrift der Gesellschaft f?r Musiktheorie. \n\n \n\nThe Researc
 h Alive Student Prize is made possible by a generous donation from Ms. Jil
 l de Villafranca and Dr. David Kostiuk.\n\nPresented as part of the Doctor
 al Colloquium Series. \n\nThis event will be webcast on our YouTube channe
 l.\n
