Key Signatures
The key of C major was discussed in Lesson 10. Songs that use notes from the C major scale are said to be in the key of C. Similarly songs that use notes from the G major scale are said to be in the key of G major. Songs in the key of G will contain F sharp (F#) notes.
Instead of writing a sharp sign before every F note on the staff, it is easier to write just one sharp sign after each clef. This means that all the F notes on the staff are played as F#, even though there is no sharp sign written before them. This is called the key signature. Tab notation does not use a key signature.
C Major Key Signature
The C major scale contains no sharps or flats, therefore the key signature for the key of C major contains no sharps or flats.
G Major Key Signature
The G major scale contains one sharp, F#, therefore the key signature for the key of G major contains one sharp, F#.
Waltzing Matilda is the most popular and well known Australian folk song. It is in four four time in the key of G major. Remember that the key signature indicates that all F notes on the staff are played as F#.
Try accompanying this song both fingerstyle and pickstyle using bass notes on beats 1 and 3 of each bar. Play the F# note on the 4th string with your fourth finger and play the F# note on the 1st string with your second finger.
