Week 3

We continue to discuss about the music theory. Jack had further elaborate about music Harmony. I learned something interesting which is Key signature. Key signature are made up of Sharp, Flat and Natural. They appear at the beginning of the music, but can also appear in other parts of the music. You can see key signature between the clef sign and the time signature. 



There are a lot of key signatures:





The picture below shows the sign of Sharp, Flat and Natural. 


A sharp sign means the note that is one half step higher than the natural note. A flat sign means the note that is one half step lower than the natural note. Most of the natural notes are a whole step apart. It cancels the sharp or flat and returns the note to its original pitch. 

For my own understanding, sharp and flat can be remembered in backwards and forwards order. And there are also rules apply when we played the key signature. When a sharp or flat appears in a key signature, all the notes on that line and all other notes with the same letter name are to be played sharp or flat. 

We also talked about music scales. There are many types of scales but we only focused on Major scale. Major scale is numbered from 1 to 8. For example, C major scale begins with a C note and ends with a C note. The same rule applies to every scales.
