Key Signatures

In looking back at the previous posts, I realized that I didn't cover key signatures. Knowing your key signatures is important. If you look at a piece of music and see two sharps (#) on the right of the treble and bass clefs, you need to know what that means. It all goes back to major scales.

Remember the major scale pattern? WS, WS, HS, WS, WS, WS, HS (WH = whole step;HS = half step). This is why we have sharps and flats in a scale. Let's look at our G major scale:                    
G, A, B, C, D, E, F#, G - notice that this pattern gives us an F#. So if you see a piece of music with F# in the key signature, you know that the song is in the key of G major.

Now let's look at the Bb major scale, using the major scale pattern: Bb, C, D, Eb, F, G, A, Bb        
See the two flats(b)? So, a piece of music with two flats is in Bb major.

Start on any note and use the major scale pattern. You will find any major key you need. In the future, we will go more in depth and study the circle of fifths. Did I hear someone groan? Regardless of what many may think, the circle of fifths is you friend. ;)
