Generative theory of tonal music in the context of Charles Eliot Norton Lectures

Ray Jackendoff (born January 23, 1945) is an American linguist. He is professor of philosophy, Seth Merrin Chair in the Humanities and was, with Daniel Dennett, co-director of the Center for Cognitive Studies at Tufts University. He has always straddled the boundary between generative linguistics and cognitive linguistics, committed to both the existence of an innate universal grammar (an important thesis of generative linguistics) and to giving an account of language that is consistent with the current understanding of the human mind and cognition (the main purpose of cognitive linguistics).

Jackendoff's research deals with the semantics of natural language, its bearing on the formal structure of cognition, and its lexical and syntactic expression. He has conducted extensive research on the relationship between conscious awareness and the computational theory of mind, on syntactic theory, and, with Fred Lerdahl, on musical cognition, culminating in their generative theory of tonal music. His theory of conceptual semantics developed into a comprehensive theory on the foundations of language, which indeed is the title of a monograph (2002): Foundations of Language. Brain, Meaning, Grammar, Evolution. In his 1983 Semantics and Cognition, he was one of the first linguists to integrate the visual faculty into his account of meaning and human language.

Alfred Whitford (Fred) Lerdahl (born March 10, 1943) is an American music theorist and composer. Best known for his work on musical grammar, cognition, rhythmic theory, and pitch space, he and the linguist Ray Jackendoff developed the Chomsky-inspired generative theory of tonal music.

Lerdahl has written numerous orchestral and chamber works, three of which were finalists for the Pulitzer Prize for Music: Time after Time in 2001, String Quartet No. 3 in 2010, and Arches in 2011. He is a Professor Emeritus of Musical Composition at Columbia University.
