## TL;DR

Music theory gives names and relationships to musical materials such as pitch, rhythm, melody, harmony, scales, chords, notation, and key structure. This entry is a compact primer anchored to a single tonal-harmony textbook source, so its confidence is intentionally low.

## Core Explanation

In a tonal-harmony course, students usually learn how notes, scales, chords, and keys relate to one another. Notation makes those relationships visible on the staff, while rhythm and meter organize musical time. Harmony focuses on how simultaneous pitches form chords and how those chords move from one place to another.

The source used here is a textbook rather than a dataset or systematic review. That makes it useful for an introductory explanation, but not enough for broad claims about all music traditions or the most common patterns across global music.
