Here, we are going to talk about two things:
Make sure that you checkout my previous article how do music notes work
We will of course talk about intervals later!
Basically, semi-tones and whole-tones are easier to see on a keyboard, and intervals are easier to see on staves.
Try to remember the sound (by playing, singing ...) of a semi-tone, and the sound of a whole-tone, as they are the fundamental elements of western music theory.
A semi-tone is the smallest distance between two notes that you can see on the keyboard:
- C and C♯
- F♯ and G
- E and F
- G and A♭
- B and C
A whole-tone is equivalent to two semi-tones:
- C and D are a whole tone apart.
- F♯ and G♯ are a whole tone apart.
- E and F♯ are a whole tone apart.
- B♭ and C are a whole-tone apart.
