Fourth or fifth
One more look at what you missed.
A perfect fourth is five half steps.
C up to F is a fourth. It is two half steps smaller than the fifth, C up to G.
A fourth, then a fifth.
No sound? Check your volume, and that your phone is not on silent.
Two tunes that open with these leaps.
Amazing Grace opens with a fourth. Twinkle, Twinkle, Little Star leaps a fifth.
Amazing Grace is the perfect 4th. Twinkle, Twinkle is the perfect 5th.
The fifth is wider and steadier.
The fourth is a little narrower, and often sounds like a call waiting for an answer. If you hesitate, sing one of the tunes.
Both leaps from the same low note.
The same two leaps, lower down the keyboard.
A fourth and a fifth together make an octave.
C up to G is a fifth, and G up to the next C is a fourth. Five and seven half steps make twelve.
So what is G up to the next C?
You can tell a fourth from a fifth.
What you learned
- A perfect fourth is five half steps, like the start of Amazing Grace.
- A perfect fifth is seven half steps, like the leap in Twinkle, Twinkle.
