This is a lecture on the concepts of propositional music illustrated by my book chapter Illusions of Form and the compositions Quartet for the Beginning of a Time (string quartet), Zones of Influence (percussion and computer/electronics), Ringing Minds (hyper-brain scanning, computer, visuals, instruments), Zones of Coherence (trumpets), and Bell Solaris (piano).
