Improvements in a drum is disclosed. The improvements include the ability for a single drum center hoop to accommodate different end hoops to replicate the acoustical properties of the 39 snare drums that are commonly used. The drum hoops are each constructed with a key that allows mating pieces to connect in only one specific location or orientation. The keying ensures that the snare bed is properly oriented for optimal tone and function of the drum snare. Each side is individually changeable, nestable and stackable to make larger drums or drums with different cosmetic features. The materials and material thicknesses are also alterable to change the resulting tonal characteristics of the drum. The membrane edge support is alterable of changeable without requiring the entire drum to be replaced.
