Today we are going to talk about interval.
Interval is simply the distance between 2 notes. As you can see on the keyboard in your house, there are white pieces and black pieces. So how we measure the distance between notes?
First, you must know the distance between 2 adjacent pieces is half tone or semi tone. Or in other words, distance between neighboring black and white pieces is semi tone.
Long story short, as you can see on the keyboard, the distance between C and D is 2 semi tone (because there is a black piece in between) or we call it tone. This interval is same with other neighboring white pieces (D to E, F to G, G to A, and A to B). Be careful for E to F and B to C. Because there is no black piece in between, so their distance must be semi tone.
To summarize this, the scale C D E F G A B Chas the following pattern of interval :
C (Tone) D (Tone) E (Semi tone) F (Tone) G (Tone) A (Tone) B (Semi tone) C or T T S T T T S for short.
Remember this pattern, because we are going to talk about Major scale next time!
