What is the typical accompaniment in waltz?

In waltz, the typical accompaniment consists of a strong emphasis on the first beat of each measure. This is usually played by the bass or left hand in piano, and is often reinforced by the drums or other percussion instruments. The right hand in piano typically plays a melodic line that flows over the top of the strong beats. The tempo for waltz is usually between 60 and 80 beats per minute, although some pieces may be faster or slower.
