MUSC101 Lecture Notes - Lecture 3: Chromatic Scale, Microtonal Music, Subdominant
Document Summary
Harmony describes the vertical aspects of music: how notes (pitches) sound together. A chord is the simultaneous sounding of three or more pitches; chords are built from a particular scale, or sequence of pitches. The most common chord in western music is a triad, three alternate pitches of a scale. Most western music is based on major or minor scales, from which melody and harmony are derived. The tonic is the central path around which a melody and its harmonies are built ; this principle of organization is called tonality. Dissonance is created by an unstable, or discordant, combination of pitches . Consonance occurs with a resolution of dissonance, producing a stable or restful sound. Harmony adds depth, determines the relationships of intervals and chords. Not all musics rely on harmony; central a lot of western systeles intervals , the distance between any two notes, can occur successively or simultaneously. Three or more notes sounded together, chord is produced.
