Define modulation between keys and give one short worked example.

# Modulation Between Keys **Modulation** is the process of changing from one key to another within a musical composition. It provides variety, drama, and forward motion to music. ## Short Worked Example **Modulating from C major to G major:** ``` C major → G major (I chord in C becomes IV chord in G) ``` **Progression:** 1. **C major** | C - F - G7 - C | 2. **Pivot chord** | Am (vi in C = ii in G) | 3. **G major** | D7 - G | **How it works:** - We start firmly in C major - **Am** serves as the **pivot chord** - it belongs to both keys - In C major: Am = vi chord - In G major: Am = ii chord - **D7** (the dominant of G) confirms we've arrived in the new key - We cadence on **G major**, now established as the tonic This is a common modulation because G major is the **dominant key** of C major (closely related keys - they differ by only one accidental).
