Direct Fifths and Octaves

Definition

Direct fifths and octaves refer to consecutive perfect fifths or octaves that occur between two voices moving in parallel motion. They are considered undesirable in traditional voice leading because they can create a lack of independence between voices.

Analogy

Imagine you're playing soccer with your friends, but instead of passing the ball to different teammates, everyone kicks it at the same time in perfect synchronization. While it may look cool for a moment, it's not ideal because you lose the dynamic teamwork and individuality that makes soccer exciting - just like how direct fifths and octaves can diminish the independence and musicality between voices.
