Just what exactly is a diminished 5th? For the title of Bach’s Halloween favorite, Toccata and Fugue in D Minor, just what does “in D Minor” mean? The answers can be found in music theory, the delineation and naming of a set of relationships between sounds that make up the toolkit of music. Here’s more from Icon Collective:
Music theory is a practice musicians use to understand and communicate the language of music. Musical theory examines the fundamentals of music. It also provides a system to interpret musical compositions.
For example, basic music theory defines the elements that form harmony, melody, and rhythm. It identifies compositional elements such as song form, tempo, notes, chords, key signatures, intervals, scales, and more. It also recognizes musical qualities such as pitch, tone, timbre, texture, dynamics, and others.
