“Die junge Nonne” (D. 828)

David Kopp has developed new strategies for music analysis that focus especially on relationships between adjacent chords. His reductions of a compositions chordal progressions, shown in music notation or with alphabet letters indicating chordal roots, are annotated using letters such as D (for a dominant relationship of a descending perfect fifth) and M (for a mediant relationship of a descending major third) between adjacent (or sometimes non-adjacent) roots. (The symbol-1 reverses the direction: D-1 indicates an ascending perfect fifth, thus the subdominant relationship.) Though his music examples lack Roman numerals, his written commentaries incorporate scale-step thinking, including tonicization.
