Editing Cadence (section)

====Perfect authentic cadence====
In a perfect authentic cadence (PAC), the chords are in [[root position]] – that is, the [[root (chord)|roots]] of both chords are in the bass – and the [[Tonic (music)|tonic]] is in the highest voice of the final chord. This is generally considered the strongest type of cadence and often found at structurally defining moments.<ref>Thomas Benjamin, Johann Sebastian Bach (2003). ''The Craft of Tonal Counterpoint'', p. 284. {{ISBN|0-415-94391-4}}.</ref> Music theorist [[William Caplin]] writes that the perfect authentic cadence "achieves complete harmonic and melodic closure."<ref>[[William Caplin|Caplin, William E]]. (2000). ''Classical Form: A Theory of Formal Functions for the Instrumental Music of Haydn, Mozart, and Beethoven'', p. 51. {{ISBN|0-19-514399-X}}.</ref>
