Circle the correct choice below and cross out the incorrect choice. This is an important difference! How much time does a dot add to the length of a note or rest?

a) A dot adds half the original length

b) A dot adds a quarter of the original length
c) A dot adds the same length as the original length
d) A dot does not add any length

Circle the correct choice: a) A dot adds half the original length.
Cross out the incorrect choices: b) A dot adds a quarter of the original length, c) A dot adds the same length as the original length, d) A dot does not add any length.

To answer the question, we need to consider the effect of a dot on the length of a note or rest. A dot adds half the value of the original note or rest.

For example, if we have a quarter note (1 beat), adding a dot would extend its duration to 1.5 beats.

Therefore, to indicate the correct choice, circle "half" and cross out any other options that may be given.
