Music Theory : Lesson 2

Let me skip other theory which I think not that important (because its too boring) and come directly to scale.

Remember I said pitch is frequency? In music theory, pitch is indicate using C, D, E, F, G, A, B only. To get higher pitch, you need to repeat that again. C, D, E, F, G, A, B, C, D, E, F, G, A, B..........
Let me change that a bit for easier understanding C4, D4, E4, F4, G4, A4, B4, C5, D5, E5, F5, G5, A5, B5.... C5 is higher frequency than C4. C4 is middle C in this example.

C4 to C5 without touching the black key on the piano is called major C scale.
w indicate whole notes and h indicate half notes. whole notes means after this notes is black key. Half note means after this is white key as below:
This w w h w w w h is called major scale.

Below indicate minor scale:
So minor scale has pattern w h w w h w w.

With this formula, we can build our own major minor scale. For example, to build D Major scale, we need to start from D and have the w w h w w w h pattern and voila:
That's all for today. Hope you enjoy the lesson today.
