In part one of my article about drumheads, I shared facts about the number of plies in drumheads and how they affect their durability and sound. This week, I'll cover three additional elements of drumheads: muffling, coatings, and bottom drumheads.

Pre-Muffled or Wide-Open Drumheads

Heads now exist with built-in muffling to prevent unwanted overtones, which is achieved is by applying a ring of material like Mylar to the drumhead's top or underside. Evans, a leading manufacturer of drumheads, offers a model with tiny-sized holes or vents along the perimeter that get rid of overtones by moving air through the membrane. Evans also offers a unique drumhead that employs a thin layer of oil between the two plies of their Hydraulic series to achieve a muffled tone.

Keep in mind that these pre-muffled heads don t change the pitch of the drum when it's tuned: they only remove unwanted extra frequencies. Pre-muffled heads can also help to remove the need for other means of muffling, like gaffer tape.

Clear or Coated Drumheads

Coated drumheads are spray-painted clear heads. While clear heads have more sustain than coated drumheads, coated heads have a sharper attack that emphasizes the sound of the stick striking the head surface (this is the primary reason why drummers traditionally use a coated head on their snare drum).

If you're playing with brushes, you definitely need to use a coated head for brush response. A coated head also has a more dampened tone than a clear drumhead - which makes sense since a coated drumhead has an extra layer of materiel applied to its surface.

Resonant or Bottom/Front Head

You get your pitch from the top or batter drumhead and your sustain from the bottom drumhead, so you'd usually only use a single-ply head on the bottom of your tom and snare drum and on the front of your bass drum.

Snare drum resonant drumheads are specifically made for the underside of your snare. They're ultra-thin and not made to be struck. This thinness helps to increase vibration and sensitivity to your snare wires.

(FYI, never install a single-ply batter head on the underside of your snare drum - unless you want it to sound like a choked cardboard box!)
