The I-IV-V progression

The I-IV-V progression is a common pattern in music where three chords are played in a sequence. It starts with the I chord (the key's home note), moves to the IV chord (a fourth above the home note), and then to the V chord (a fifth above the home note). This progression creates a sense of movement and resolution, often forming the backbone of many songs. It provides a familiar, pleasing structure that feels natural to the ear, making it a fundamental building block in Western music across genres.
