Explore Music Theory with clear music dictionary guides to notes, scales, chords, rhythm, harmony, melody, and musical structure.
A deceptive cadence is a harmonic progression that subverts the expected resolution from the dominant chord to the tonic, typically moving to the vi chord instead. It creates surprise and prolongs tension, and is a staple of tonal music from the Baroque era to contemporary pop.
A compound interval is a musical interval that spans more than an octave, such as a ninth or thirteenth. It is measured by counting the number of scale degrees and quality, extending the principles used for simple intervals.
Atonality is a compositional approach that deliberately avoids establishing a key centre, emerging in the early twentieth century and reshaping modern music theory and practice.
The Lydian mode is a diatonic musical scale that can be thought of as a major scale with a raised fourth degree, giving it a bright, floating quality.
Subdivision in music refers to the practice of breaking a beat or a larger rhythmic value into smaller, regular units, enabling precise timing and complex rhythmic patterns.
In music, a mode is a type of scale characterized by a specific pattern of intervals, forming the basis for melody and harmony. Modes have been used across cultures and eras, from ancient Greek theory to modern jazz and folk traditions.
A hemiola is a rhythmic device that temporarily shifts the perceived beat grouping, creating a feeling of two beats in the time of three (or vice‑versa). It is widely used across classical, folk, and popular music to add tension and variety.
Rhythm is the temporal pattern of sounds and silences that gives music its flow and structure. It involves the organization of beats, accents, and durations, shaping how listeners experience a piece.
A chord inversion rearranges the order of notes so that a note other than the root occupies the lowest pitch. This technique is fundamental to voice leading, harmonic variety, and bass‑line movement across many musical styles.
Monophony is a musical texture consisting of a single melodic line without harmonic accompaniment. It appears in chant, folk traditions, and certain modern styles, offering a clear, unison sound.
