In [[music theory]], an '''augmented sixth chord''' contains the [[interval (music)|interval]] of an [[augmented sixth]], usually above its [[bass note|bass tone]]. This [[chord (music)|chord]] has its origins in the [[Renaissance music|Renaissance]],{{sfn|Andrews|1950|pp=45–46}} was further developed in the [[Baroque music|Baroque]], and became a distinctive part of the musical style of the [[Classical period (music)|Classical]] and [[Romantic period (music)|Romantic]] periods.{{sfn|Andrews|1950|pp=46–52}}

Conventionally used with a [[predominant chord|predominant]] [[diatonic function|function]] ([[resolution (music)|resolving]] to the [[dominant (music)|dominant]]), the three most common types of augmented sixth chords are usually called the ''Italian sixth'', the ''French sixth'', and the ''German sixth''.
