One of the most important sounds you can train your ear to recognize. Perfect fifths are important because they’re stable, open, and show up constantly in real music, which makes them a reliable reference point for hearing harmony and melody. As you listen, pay attention to how clean and grounded the interval feels, there’s no tension, just strength and space. You’ll hear perfect fifths in bass lines, melodies, power chords, and even in how instruments are tuned, so once your ear locks into this sound, you’ll start noticing it everywhere.

May the force be with you, always.
