Upbeat (music)
In music, an upbeat (also called a pickup or anacrusis) is the unaccented portion of a phrase that precedes the first strong beat of a measure. It appears in notation as notes before the bar line and serves as a preparatory cue for performers.
Triad (music)
A triad is a three‑note chord built from stacked thirds, forming the basic harmonic unit in Western music. Its quality—major, minor, diminished, or augmented—determines its emotional character and functional role within a key.
Deceptive Cadence
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.
Compound Interval
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
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.
Lydian mode
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 (music)
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.
Mode (music)
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.
Hemiola
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.
