Sharps and Flats
We just learned that the musical alphabet consists of the notes A, B, C, D, E, F and G. It is also important to know that there are 'sharps and flats' (also called accidentals) between most of these letters. We use the hash mark (#) to indicate a sharp and the letter ‘b’ to indicate a flat.
Sharps and flats can be applied in two ways. When we want to make note, for example a C, sharp, we end up with C#. On a piano keyboard, this is exactly the same key as 'D flat' or Db. Likewise, D# is the same key as Eb and so on. Practice this using the picture above; try to name each black key. You will find the correct results below.
Did you succeed? Feel free to repeat the exercise a few times until you have fully mastered the principle. We will come back to this later in this chapter. First, we will go deeper into musical intervals and discover how to start building notes within a certain key. Once we've reached that point, you can create different musical families and we're off!
