Perfect intervals together
One more look at what you missed.
Played together, perfect intervals sound hollow.
They blend so well that they sound open and plain, with no bright or dark colour like a third.
A fourth, a fifth and an octave, together.
No sound? Check your volume, and that your phone is not on silent.
A rock guitar's power chord is a fifth.
Guitarists play a note and the fifth above it, often with the octave on top. That heavy, hollow sound is the fifth.
A power chord, then a third for contrast.
The third has a colour, bright or dark. The power chord has none.
Almost one note: octave. Two notes fused, strong: perfect 5th. A bit less settled: perfect 4th.
Listen for how much the two notes blend.
The octave sounds almost like one note, and the fifth like two notes fused. The fourth sounds a little less settled than the fifth.
A fifth and a fourth, side by side.
Just the two that sound alike: the fused perfect 5th, or the less settled perfect 4th.
You can hear perfect intervals played together.
