How can you make maracas have a high and low pitch?

To create maracas with a high pitch, use smaller, lightweight materials for the filling, such as beads or rice, and choose a smaller container for the maracas. For a lower pitch, opt for larger, heavier fillings like dried beans or larger stones, and use bigger containers. The shape and size of the maracas also influence the pitch, with narrower shapes generally producing higher sounds and wider shapes resulting in lower tones. Adjusting the amount of filling can further refine the pitch.
