This thesis treats Daniel Read's music analytically to establish style characteristics. Read's fuging tunes are examined for metric placement and structural occurrence of dissonance, and dissonance as text painting. Read's comments on dissonance are extracted from his tunebook introductions. A historical chapter includes the English origins of the fuging tune and its American heyday. The creative life of Daniel Read is discussed. This thesis contributes to knowledge of Read's role in the development of the New England Psalmody idiom. Specifically, this work illustrates the importance of understanding and analyzing Read's use of dissonance as a style determinant, showing that Read's dissonance treatment is an immediate and central characteristic of his compositional practice.
