accordo

This article describes musical chords in traditional Western styles. For information on non-Western styles, consult the articles specific to those styles. In music and music theory a chord (from Greek χορδή: gut, string) is three or more different notes that sound simultaneously. Most often, in European-influenced music, chords are tertian sonorities that can be constructed as stacks of thirds relative to some underlying scale. Two-note combinations are typically referred to as dyads or intervals.
