Yellow Bell Calculation Method

• Set 1, multiply by 3 nine times (3^9 = 19683) as divisor
• The result is 1 寸
• Total: 9 寸 = Yellow Bell standard

Key Principles

• 音始於宫，穷於角
• 数始於一，终於十，成於三
• 气始於冬至，周而复生

Application

Use this standard to:

• Calibrate musical instruments
• Establish weights and measures
• Determine seasonal timing

Validation

1. Confirm the base calculation produces 3^9 = 19683 as the divisor and 9 寸 as the Yellow Bell standard
2. Verify each successive pitch is correctly derived using powers of 3 from the base unit
3. Check that the derived standard is consistent across its three application domains: musical tuning, weights/measures, and seasonal timing
