What is tritone substitution?

Tritone substitution involves replacing a dominant seventh chord with another dominant seventh chord, tritone (three whole steps or six half steps) away. It’s like a musical sleight of hand that adds a captivating sense of tension and chromatic movement to your compositions.

To grasp the essence of tritone substitution, let’s break it down into bite-sized chunks:

The secret behind the substitution

  • A dominant seventh chord consists of the root, major third, perfect fifth, and minor seventh intervals.
  • In tritone substitution, you replace the original dominant seventh chord with another dominant seventh chord whose root is a tritone away.
  • The tritone interval creates a unique dissonance, making the substitution intriguing and captivating.

Jazz’s best-kept secret

Now, you might be wondering, “Where does tritone substitution shine the brightest? The tritone substitution is extensively used in jazz music, adding a touch of sophistication to harmonic progressions. Here’s why it’s jazz’s go-to trick:

  • It creates smooth voice leading, allowing for seamless transitions between chords.
  • It adds richness and complexity to chord progressions, expanding the harmonic palette.
  • It provides opportunities for exciting improvisation, opening doors to new melodic possibilities.

What is the i-iV-iii-Vi to ii-V-i turnaround?

The i-iv-iii-vi to ii-v-i turnaround is a common chord progression used in jazz music. It serves as a transitional sequence that leads back to the beginning of a song or moves from a bridge section back to the A section. The progression creates a sense of forward motion and tension, ultimately resolving to the tonic chord. It is a nifty chord substitution technique that breathes new life into your music.

Let’s unravel the secrets behind this transformation:

Rewriting the Progression

  • The I-IV-III-VI progression represents a common chord sequence often found in pop, rock, and other popular music genres. It provides a solid foundation for many catchy tunes.
  • By substituting the I-IV-iii-VI with an ii-V-I progression, you infuse your music with a smoother harmonic flow, enhancing the overall structure and musical journey.

The Power of the ii-V-I Substitution

  • ii (the supertonic) sets up tension and prepares for resolution.
  • V (the dominant) adds a layer of anticipation and pulls the listener toward the tonic.
  • I (the tonic) bring resolution and a sense of stability, concluding the progression with a satisfying resolution

What are chromatic ii-V’s?

Chromatic ii-V’s are like the hidden gems of chord substitutions, injecting a burst of color and tension into your progressions. So, let’s break it down, shall we?

Going Beyond Diatonic Boundaries

  • Chromatic ii-V’s take things up a notch by adding chromaticism, which means incorporating notes outside the key signature.
  • These chromatic infusions spice up your progressions, bringing unexpected twists and turn to captivate your listeners.

The Art of Chromatic ii-V Substitutions

Now, you might be wondering, “How can I wield the Power of chromatic ii-V’s in my music? Here are some tips to get you started:

  • Experiment with chromatic ii-V’s to create tension and resolution in your progressions.
  • Utilize chromatic passing chords to add interesting chromatic movement between your primary chords.
