Music is written on a staff, which consists of five parallel lines between which there are four spaces.
All drum music begins with a bass clef sign. This is also used for low pitched instruments such as the bass guitar and the bass line of a piano music piece.
Bar Linesare drawn across the staff, which divide the music into sections called bars or measures. A double bar line signifies either the end of the music, or the end of an important section of it.
