A '''chord''' is a collection of notes with well-defined pitches sounding together, or sometimes suggested in some manner, such as arpeggiation. | A '''chord''' is a collection of notes with well-defined pitches sounding together, or sometimes suggested in some manner, such as arpeggiation. | ||
A chord's ''form'' is a description of its general structure, often using established categories (e.g. "[[major triad]]") or extensions thereof (e.g. "[[supermajor triad]]"), which summarize the intervals that constitute the chord. Most chord forms are named after the [[interval qualities]] of the intervals of the chord (e.g. "[[minor-major seventh chord]]"), while a few others are named after a {{w|Function (music)|harmonic function}} (e.g. "[[dominant seventh chord]]") or other composition techniques (e.g. "[[suspended second chord]]") when they are strongly associated. Chord forms do not provide precise tuning information, instead relying on [[interval region]]s to include a variety of similar chords. | |||
A chord's ''function'' is a description of the context in which a chord is used, including how it relates to neighboring chords and to the scale upon which it is built (e.g. "Neapolitan" for a chord built on the ♭II degree of a scale). | |||
