Example 1. BHMB Representation in current theory textbooks
“CPP %” indicates the percentage of examples that were drawn from music between roughly 1700–1900, the “common practice period” of tonal harmony; as can be seen, some texts include earlier and later musical examples and styles, while others focused exclusively on CPP (or nearly so). BHMB % refers to the percentage of CPP examples that are by Bach, Haydn, Mozart, and Beethoven; BHMB+ % adds examples by Chopin, Schubert, and Robert Schumann. Example counts are drawn from example indexes in each volume; Turek example counts are from the recorded example list. Examples that appear multiple times are only counted once, as per the indexing-note that counting every appearance of every example would inflate the BHMB %.
