In this first post, I am going to talk about the differences between letter and number representation of musical notes which often being mistaken. This case happens in most of my friends who worked in music for the first time.
Look at this picture :
There are two different representations of the musical note. The piano shows where the C D E F G A B stands. Below you can see the numbers representing it. The number below is representing the “do re mi fa sol la ti”. So what is the difference?
Okay, the sole difference of these two representation is their position on the musical notation or keyboard. C D E F G A B is always in the same place on the notation (E is always on the first line from below, F is always on the first space from below, G is always on the second line from below, and so on) while “do re mi fa sol la ti” or 1 2 3 4 5 6 7 can be on different places at different time.
For example, if you are a choir singer, you may find in your music sheet:
Do = G
This means that “do” or 1 is the same sound as you play G note on the piano. Therefore, “do” or 1 is on the second line from below in this song. The other number will follow–“re”(2) is A, “mi” (3) is B, “fa” is C, and so on. But be careful, in this song, “ti” (7) will be F#. We will talk about it later.
You may find other notation like Do = A, Do = D, or any other. So theoretically, “do re mi fa sol la ti” refers to the notes in major scale (which we will talk about it later) and its interval relation.
I hope this explanation can clear your mind about the differences. So, when you read the musical notation, make sure to read it C D E F G A B than “do re mi fa sol la ti”.
