Module 2: Tuning Systems and Theory

Explore various tuning systems and the theory behind microtonal music.

Lesson Content

1. Just Intonation

Understanding the principles of Just Intonation:

  • Ratios and harmonics
  • Advantages and limitations
  • Historical and contemporary uses

Audio Example: Just Intonation vs 12-TET

2. Equal Temperaments Beyond 12-TET

Exploring alternative equal temperaments:

  • 19-TET: A closer approximation of just intervals
  • 31-TET: Increased harmonic possibilities
  • Other EDOs (Equal Divisions of the Octave)

3. Non-Octave Tunings

Venturing beyond octave-based systems:

  • Bohlen-Pierce scale
  • Wendy Carlos's Alpha and Beta scales
  • Creating your own non-octave tunings

4. Theoretical Foundations

Understanding the mathematical and acoustic principles:

  • Frequency ratios and cents
  • Harmonic series and its relationship to tuning
  • Psychoacoustics of microtonal intervals
