This pattern continues up and down the keyboard.
The note names of the white keys are:
This key pattern repeats on the keyboard so that the note names of the white keys keep repeating: CDEFGAB-CDEFGAB-CDEFGAB and so on.
Sharps and Flats:
If we take a white key, D for example, and we go up (to the right) to the adjacent black key we are now on the note D-sharp. If we go down (to the left) to the adjacent black key from D we end up on the note D-flat. This is how we determine the names of the black keys and therefore all black keys will be a sharp or flat note.
You may have noticed that black keys can have more than one note name. For example C-sharp and D-flat are on the same black key, but which name we should use depends upon context, such as the Key Signature.
Half-steps and Whole-steps:
A Half-step is the distance of two adjacent notes, such as D to D-sharp, E to F, or A-flat to G. (A half-step is also known as a minor second.)
A Whole-step is the distance of two Half-steps, such as C to D, E to F-sharp, or B-flat to A-flat. (A whole-step is also known as a Major second.)
