Step 3
Hear the difference between perfect 4th and perfect 5th
This lesson teaches more spatial hearing inside the octave. The perfect 4th can feel balanced but slightly suspended, while the perfect 5th usually feels more complete and settled.
What to notice
- Perfect 4th: balanced, but often a little less final.
- Perfect 5th: open, stable, and more resolved.
- Compare both against the 3rds you already know.
Why this lesson matters
This step helps your ear move beyond simple bright-versus-dark contrast and start hearing position and space more clearly.
