Music Theory Verification

Overview

Music theory code involves modular arithmetic (mod 12) and interval calculations. Small errors produce completely wrong notes that may not be obvious until heard.

Core principle: Verify calculations against known musical facts before trusting code.

When to Use

• Debugging incorrect note display
• Verifying new scale/chord implementations
• Troubleshooting Nashville number display
• Checking fretboard/keyboard generation
• Validating transposition logic
