Music Theory Rules

Introduction

  • Music theory does not have strict rules as law or legislative bodies do.
  • Music theorists do not enforce legal standards for music.
  • The concept of rules in music exists but varies in rigidity.

Spectrum of Music Rules

Immutable Rules

  • Rules of Limitations
    • Instruments have physical limitations (e.g., certain notes not possible).
    • Human physical limitations (e.g., need to breathe, finger movement restrictions).
  • Rules of Physics
    • Physical constants in music (e.g., harmonic series).

Rules of Style

  • Certain styles aim for specific aesthetics and have their own rules.
  • Counterpoint Rules
    • Example rules: Avoid parallel fifths, no melodic tritones.
    • Often perceived as universal but specific to a style.
  • Breaking rules is possible and historical (e.g., J.S. Bach's use of parallel fifths).

Subjective Rules

  • Emotions and descriptive terms in music are subjective (e.g., happy, sad).
  • Subjective interpretation varies widely among listeners.
  • Conventions can seem like rules but aren't (e.g., minor key perceived as sad).

Conventions in Music

  • Conventions of Style/Genre
    • Instrumentation expectations (e.g., rock band instruments).
    • Chord progressions differ by style (e.g., Baroque vs. modern loops).
  • Tendency Tones
    • Notes/chords often resolve a certain way but don't have to.
    • Following or breaking these tendencies can create effects.
  • Naming Conventions
    • Musical terminology is agreed-upon and can change over time.
    • Standard nomenclature aids communication.

Good Ideas

  • Best practices based on practicality and experience.
    • Examples: Vocal range, orchestral balance, instrument capabilities.

Conclusion

  • Music theory should examine music on its own terms, not impose hierarchies.
  • Encourages creativity and breaking rules for artistic expression.
  • Music theory: a set of analytical tools, not restrictive rules.
