We must accurately measure the duration of silences in music, just as we measure the length of sounds. We call the symbols that indicate the duration of a silence rests.Just as we have symbols that indicate note values, we likewise have symbols that indicate rest values. Figure 24 shows the rests that will be used in the Grade 1 course:
The whole rest and the half rest look very similar, but the whole rest is written below the line, while the half rest is written above the line. Generally, the whole rest is written below the 4th line, and the half rest is written above the 3rd line, as shown in Figure 25:
The positions of the other rests are as follows (unless there is a particular reason for them to be placed higher or lower), as shown in Figure 26:
A completely silent bar can be indicated by a whole rest — not only in 4/4 time, but also in 2/4 and 3/4 time.
