Imagine that you're going to a parade to watch soldiers march by. You might notice that some of the soldiers have drums with them. These soldiers are called the "corps of drums."
The corps of drums is a group of soldiers who play percussion instruments like drums and cymbals as part of a bigger military band. They march alongside the soldiers and help keep the rhythm of the music.
Drums come in lots of different shapes and sizes, and the corps of drums might have all kinds of them in their group. There are big bass drums that you hit with a special mallet, snare drums that are smaller and have a tighter sound, and cymbals that make a loud crashing noise.
Being part of the corps of drums means that you have to be really good at playing your instrument and following directions. When the commander says to start playing, everyone in the corps of drums has to do it at the same time. If someone makes a mistake, it could throw off the whole band and ruin the performance!
Overall, the corps of drums is a really important part of any military band. They add a bold, exciting sound to the music and help keep the soldiers in step.
