If you read the line, “Chestnuts roasting on an open fire, Jack Frost nipping at your nose”, would you sing it?

For many, these words will have you singing the opening lyrics to The Christmas Song, a classic festive work written in 1945 by Robert Wells and Mel Tormé.

According to the American broadcast rights company, Broadcast Music, Inc., it is the most performed Christmas song, and classic covers include renditions by Nat King Cole, Bing Crosby, Christina Aguilera, and most recently Jacob Collier’s cover was nominated for Best Arrangement, Instrumental and Vocals at the 64th Annual Grammy Awards.

But what if we told you that this timeless classic was also a great way to brush up on your music theory knowledge? Take a listen and we’ll explain more below...

The music theory song

Listening to The Christmas Song, you could be forgiven for thinking it’s a simple melody.

Chances are, you’ve sung it many times and are so familiar with the tune, so don’t think twice about the makeup of this famous work.

However, American composer David Rakowski would say otherwise. Rakowski, a former student of Luciano Berio, wrote alternative lyrics to The Christmas Song, which encapsulate the multiple fundamentals of music theory which appear throughout the melody of the Christmas classic. Further lyrics were added by former music theory teacher, Dave Swenson.

The Music Theory Song (Intervals Roasting)

In the song, the lyrics highlight intervalic patterns, and different types of scales and cadences. The song even quotes a line from the theme song of the 1960s animated television series, The Flintstones.

Opening with a defiant example of a perfect octave (middle C, to the C above, are the first two notes of the piece), the song throws the listener straight into music theory land. Scales are also quickly illustrated in the second line of the piece, with both examples of a diatonic scale (G-F-E-D-C), and a chromatic alteration of the same scale a bar earlier.

The idea of a motif is also introduced to the listener (a phrase of music which comes back repeatedly in a piece) and is easy to identify as the opening melody when it comes back at the end of the song, by the helpful lyrics ‘A motif used to build this simple phrase’.

Attaching lyrics to famous pieces of music, or creating mnemonics, have long been a part of music teachers’ syllabuses, to teach young musicians fundamentals.

For example, the mnemonic ‘Every Good Boy Deserves Fudge’, is commonly used to teach those new to music, how to read the lines on a treble clef staff.
