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.
