This blog post explores the key modulation techniques used by composer John Williams, detailing three levels of difficulty: direct modulation, melodic walks, and harmonic changes, with examples from his iconic scores.
In this blog post, we will delve into the fascinating world of key modulation as exemplified by the legendary composer John Williams. We will explore three distinct techniques he employs to change keys in his compositions, providing examples from his well-known tracks. Whether you are a budding composer or simply a music enthusiast, understanding these techniques can enhance your appreciation of film music.
Key modulation, or changing keys within a piece of music, serves various purposes, such as creating emotional shifts or enhancing narrative elements in film scores. If you are curious about the significance of changing keys, I recommend checking out a video that discusses this topic in detail.
The first technique we will examine is the direct modulation, which is often surprising and impactful. In traditional harmony studies, modulating between keys typically involves finding a common chord to serve as a pivot. However, John Williams frequently bypasses this method, opting instead for a more abrupt transition.
In the piece "Harry's Wondrous World," Williams transitions directly from D-flat major to C major without any preparatory chords. This sudden shift not only changes the key but also introduces a significant alteration in texture, tempo, and overall feel.
Another instance occurs in "Rey's Theme" from The Force Awakens, where he transitions from B-flat minor to B minor in a seamless manner. This technique can be particularly effective in film scoring, as it jolts the listener awake and emphasizes a dramatic moment in the narrative.
For those looking for an easy way to change keys, consider modulating up a minor third, which tends to work well without altering much else in the music.
While direct modulation is effective, a smoother transition is often desired. John Williams frequently employs a technique I refer to as the melodic walk, which involves ascending a scale or arpeggio to land on a strong chord tone in the new key.
In "Harry's Wondrous World," Williams modulates from A minor to C minor by having the melody walk up the notes A, B, and C. This straightforward approach highlights Williams' genius in utilizing clear and effective techniques.
At times, Williams incorporates the octatonic scale, which consists of alternating whole and half steps. This scale can create a sense of instability, making it an excellent choice for transitioning out of a key. For instance, in "Rey's Theme," he walks up an octatonic scale to modulate from B minor to D minor, landing firmly on D, which is not part of the octatonic scale used. This technique gives the modulation a sense of destination.
In "Fox and the Phoenix," Williams extends the octatonic walk over four bars to transition from A major to C major, landing on C, the tonic of the new key. This method reinforces the feeling of a solid arrival point in the new key.
The third level of modulation involves harmonic changes, which many might expect when discussing key changes. Interestingly, Williams uses harmony to modulate as frequently as he employs direct jumps to new keys.
In "Harry's Wondrous World," Williams transitions from C major to F major using a clever harmonic technique. The chords C and F are diatonic to C major, but he introduces the E7 chord, which is borrowed from the relative minor, A minor. This creates a deceptive cadence, where instead of resolving to the expected tonic, he surprises the listener by moving to the F major chord.
This modal borrowing adds an exotic and colorful quality to the music, enhancing the fantasy elements of the score. Additionally, the E7 chord is presented in second inversion, a technique that Williams also employs in other works, adding further depth to his harmonic language.
John Williams' mastery of key modulation showcases his innovative approach to composition. By utilizing direct modulation, melodic walks, and harmonic changes, he creates music that is both engaging and emotionally resonant. Understanding these techniques not only enriches our appreciation of his work but also provides valuable insights for aspiring composers.
Thank you for exploring these key modulation techniques with me. I hope you find inspiration in your own musical endeavors!
