Composition for Comparison: "Twist and Shout" by the Beatles and "Surfer Girl" by the Beach Boys

The elegant melodies of Binchois inspired a generation of musicians and Dufay's epic compositions elicit awe and respect even from modern listeners, but the real revolution of Renaissance music began with John Dunstaple. This great English composer is credited with introducing a technique that is often taken for granted by the 21st-century ear: triadic harmony.

In short, a musical triad consists of the root, third, and fifth of a major scale and contains intervals of a third between successive notes. For you music-theory beginners out there, I've selected some modern, well-known songs to demonstrate what this sounds like. The first is "Twist and Shout" as performed by the Beatles, a rendition that should be familiar to anyone who has seen Ferris Bueller's Day Off. The majority of the song uses a single lead vocal with a pair of backing harmonies, but if you play to 1:25 into the recording, you'll hear the Beatles build into a triadic harmony, one note at a time. It begins with John Lennon singing the root note ("Ahhh...") over the twanging of George Harrison's lead guitar. Next George chimes in with the third, followed soon after by Paul with the fifth. At 1:28, they're in a full triadic harmony. It only holds a complete triad for the few seconds after 1:28 -- the sequence continues after that to the seventh, breaking the triad. The notes of a triad can also be struck simultaneously: C Triad.

It's not uncommon to hear full triadic harmony in modern music, particularly in pop music of the '50s and '60s. In "Surfer Girl," a song by the Beach Boys from 1963, they utilize it throughout much of the song, crafting the melody over top of the moving triads. In fact, the arrangement is in many ways similar to that of "Quam Pulchra Es," one of John Dunstaple's motets from the mid-15th century. This motet is one of the more blatant examples of how the interval of a third was being gradually promoted to the status of a consonance (that is, a stable musical interval) in the early Renaissance period. For those that have been following my Journey, this sudden addition of musical triads should be a very noticeable (and very welcome) change to early polyphony. Compare it to this early mass movement by Guillaume de Machaut, where fourths, fifths, and octaves dominate the harmonic structure. Although such intervals achieve a more "pure" sound, they are almost too easy for the human brain to process and we may be left feeling like something is missing.

Triadic harmonies were commonplace through most of the 15th century in England, but it won't be until the late 15th and early 16th centuries that the musical changes initiated by John Dunstaple and his English contemporaries begin to permeate the music coming from continental Europe. Unfortunately, because of Henry the VIII's dissolution of the monasteries in the 1530's, very little music survives from England in the preceding century and the process by which triadic harmony was introduced into polyphony may forever remain a mystery. Dunstaple was famous enough that some of his music has come down to us from continental sources, but the catalog of surviving music doesn't even approach that of contemporaries like Dufay and Binchois. This is indeed a shame, as many argue that John Dunstaple was the most influential English composer of all time.
