Timpani were originally used in official bands. They can still be seen in the bands of the modern official as in the Household Cavalry of Queen Elizabeth II of the United Kingdom, in which the "kettle drums" (as they are called) are carried by large drumhorses. In the 1700s timpani became popular in orchestral music, and can be heard in the music of Handel, Beethoven and other 19th century composers wrote music that needed the timpani. Nowadays all large orchestras have timpani, and some bands that play popular music use them as well.
