If you look at example 13 on the following page, you will notice a line of letters and symbols above the staff(G, Em, Am etc.) These are chord symbols which indicate the harmony to be played by accompanying instruments such as keyboard or guitar.

This time signature is called the three four time signature. It tells you there are three beats in each bar. Three four time is also known as waltz time. There are three quarter notes in one bar of ^ time.
A dot written after a note extends its value by half.
A dot after a half note means that you hold it for three beats.
One dotted half note makes one bar of music in ^ time.
