occur when notes are played simultaneously, creating "vertical" sonic behavior.

Considered highly stable and consonant; the backbone of traditional chord construction.

: Intervals are typically taught within the context of the major scale , relating each note to a numbered distance from the root (e.g., major 3rd, perfect 5th). Melodic vs. Harmonic :

Created by lowering a major interval; often used to evoke sadness or tension. 3. Harmonic Behavior: Consonance and Dissonance

The report "Intervals I" explores the foundational role of intervals as the building blocks of musical structure, focusing on their theoretical classification, physical properties, and emotional impact. 1. Fundamental Classification and Measurement

The perception of an interval changes based on its environment. For example, a may be perceived as "tense" in a consonant setting but "consonant" in a highly dissonant one.

: Effective composition relies on creating tension with dissonant intervals and providing "resolve" to stable ones.
