Theory IV is a continuation of the historical-analytical work of MUSC 251, focusing on study of chromatic harmony, as well as an introduction to form and analysis and 20th century compositional techniques. Specifically, application of chromatically altered chords (Neapolitan, borrowed, and augmented sixth chords) is followed by an introduction to form & analysis (a study of binary, ternary, rondo, variation and sonata forms). At the end of the semester, students will be introduced to atonal and serial music of the 20th century. Required course work includes analysis, aural skills training, sight singing, composition, and use of Finale and Noteflight music writing software. Prerequisite: 251. QL
