<u>Quartal Harmony</u> uses == Pre-Reqs ==* [[C Major Chord]] for introduction to chords built on 4th intervals, rather than the common 3rds (called <u>Tertian Harmony</u>). For example, a common C major triad is (C E G), featuring a M3 between C and E and a m3 between E using tertian harmony* [[Atonality and G. A Serialism]] for possible applications of quartal chord would instead appear similar to (C F B{{b}}) - a P4 between C and F and another P4 between F and B{{b}}. Not only can we use the P4, but also the d4 and A4 intervals.harmony* [[Extended Chords]]

'''Quartal Harmony''' uses chords built on 4th intervals, rather than the common 3rds (called '''Tertian Harmony'''). For example, a common C major triad is (C E G), featuring a M3 between C and E and a m3 between E and G. A quartal chord would instead appear similar to (C F B{{Advanced Lesson Crumbs|12b}}) - a P4 between C and F and another P4 between F and B{{b}}. Not only can we use the P4, but also the d4 and A4 intervals.

== Quintal Harmony ==
Just as there is Quartal Harmony built on 4ths, there is <u>'''Quintal Harmony</u> ''' built on 5ths. However, I do not feel there is any necessity to explore it here, as it is essentially the inverse of Quartal Harmony. For example, look at the following chords:
{|class="wikitable"
! Quartal Chord !! Equivalent <br>Quintal Chord
|-
|
And since standard guitar tuning using 4ths, this makes quartal chords significantly eaiser to finger than quintal chords.
