Chordsthat

Chordsthat is a term used to describe a conceptual reference, database, or tool in music theory and education that focuses on chords and the relationships between them. In different contexts, chordsthat can denote a collection of chord definitions, examples of progressions, or a framework for exploring how chords typically follow one another in tonal harmony and other musical systems.

A chordsthat resource typically categorizes chords by root note, quality (major, minor, diminished, augmented, seventh and extended forms), and harmonic function (tonic, subdominant, dominant). It emphasizes voice-leading considerations, inversions, and the role of scale context, often incorporating circle-of-fifths relationships and common modulation patterns.

Users leverage chordsthat to learn which chords are likely to succeed after a given chord, to generate plausible progressions, and to study substitutions and variations. Educators use it to illustrate functional harmony, while composers and arrangers reference it for inspiration or to test alternative voicings and tonal paths. Interactive features may include search, playback, and transposition.

Data for a chordsthat resource may be drawn from standard music-theory literature, published chord dictionaries, and user-contributed examples. Implementations may combine rule-based constraints with heuristic similarity measures to suggest chords that fit a functional or stylistic goal, while allowing users to modify voicing and rhythm.
