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 ''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).

== Chord inversion, or rotation ==
{{Wikipedia|Inversion (music) #Chords}}
An '''inversion''' of a chord typically refers to a [[rotation]] of a chord, that is, a setting where one of the pitch classes is chosen as the lowest note. For example, a C major triad contains the tones C, E and G; its inversion is determined by which of these tones is the lowest note in the chord.
== Melodic inversion ==
{{Wikipedia|Inversion (music) #Melodies}}
'''Melodic inversion''', by contrast, describes literally ''inverting'' a chord, i.e. putting a chord upside-down. The two chords are ''inverses'' of each other. A chord whose inverse is itself is a ''palindromic chord'', or ''palindrome''. In {{w|negative harmony}} theory, chords are inverted with respect to the midpoint of the tonic and the fifth.
