Music is written on a staff, which consists of 5 parallel lines between which there are 4 spaces.
All drum music begins with a percussion clef sign. This sign distinguishes the difference between the treble clef and bass clef, used for low pitched instruments such as the bass guitar and the bass line of a piano part.
Bar Lines are drawn across the staff, which divide the music into sections called bars or measures. A double bar line signifies the end of an important section of music, while a final bar line is written at the end of a piece.
At the beginning of each piece of music, after the bass clef, is the time signature e.g.:
The Time Signature indicates the number of beats per bar (the top number) and the type of note receiving one beat (the bottom number).
* is the most common time signature and is sometimes represented by this symbol Q called common time.
Other time signatures used in this book are:%, ^, I, ) and U time.
