ABSTRACT
Harmony is the vertical component of music. When two or more pitches are sounded simultaneously harmony is produced. Harmonic is the adjective that applies to pitches “sounded at the same time,” as opposed to melodic, which, as the reader knows, is the adjective that means note after note. Intervals were discussed in part 2, where the measuring of musical distances was considered in the context of melody. But one needs to discuss and measure pitch distances in the harmonic context, too.
