Marching snare drums nowadays have a high tension snare on the bottom head. Snarelines can consist of 2-12 snare drummers. Usually, 4-5 are found in high schools bands, while 7-10 are common in drum corps.
The two main grips for a snare drummer are Matched Grip, which have the hands looking the same. The one that is used more is Traditional Grip, which makes for better diddle sound. This makes the left hand form different than the right.
