What are the different types of mallets?

There are several types of mallets, stretching from Bell kit plastic mallets, to yarn Marimba mallets, to Timpani Mallets, and all the way to Bass Drum Mallets. Marimba mallets come in different sizes so you can have a different echo and tone when you are playing. Bell Kit mallets are hard so the sound rings out, same with Timpani mallets, except they have soft ends that vibrate the heads of the Timpani, causing the echo all percussionists appreciate, and bass drum mallets have soft but firm ends so that when they strike the head of the drum, it delivers the BOOM all band directors love.
