Choosing an appropriate acoustic drum kit for a studio, school, or church can lead to a number of questions. This guide will help you understand the fundamental characteristics of drums so that you can make an informed choice. As always, your BAJAAO Sales Engineer has loads of information about drum-related issues.
Top (batter) head
The most basic component of a drum, the head is a round membrane — made of plastic or animal hide — that is stretched across a shell, with varying degrees of tension (tightness).
A modern drum hoop is most often made of either cast or stamped metal (although many drummers prefer wood hoops), and it contains a flange shaped to hold the head on the shell for tensioning.
Tension rods mount through holes in the hoop and thread into the lug to maintain the desired tension.
Lugs are normally made of metal and mount on the shell to receive the tension rods. Lug designs can vary from simple to very complex, and they often contain alignment springs and other features.
Other than the head, the shell has the most significant impact on the drum’s tone. Most shells are made of wood, but fiberglass, acrylic, and more exotic shells can be found.
A vent is simply a hole that allows air pressure to be released when the drumhead is struck. Not all drums have vents.
Bottom (resonant) head
A drum’s resonant head plays an important role in defining both the attack and the tone. Most resonant heads are thinner than the top (batter) head.
The bottom hoop holds the bottom head on the drum. On snare drums, the bottom hoop includes slots to accommodate the snares (see below).
The snares — a series of coiled wires stretched across the bottom head — give the snare drum its characteristic “snappy” sound.
This lever-and-thread device allows the drummer to adjust the snare tension and also to disengage the snares entirely from the head for a tom sound.
This specialized hoop contains slots in its sides to allow the cords or straps holding the snares to pass through.
Although there can be dozens of different drum kit configurations, most begin with these components:
A shell pack most often includes only the bass drum and the toms. Items such as the snare drum, the stands, and the pedals must be purchased separately. Shell packs are popular because most drummers have very specific preferences for the snare drum, pedals, and other hardware they use.
You may have seen drummers in concert or on the screen whose kits included a multitude of toms. The reality is that the bass drum and the snare drum are the primary components of a drum kit. Toms are most often used for “fills” — rhythmic phrases that provide a transition from one part of a song to the next. The number of toms used is largely a matter of a drummer’s personal preference, but a basic kit should include at least one small tom (usually mounted on the bass drum) and one large tom (often called a floor tom).
From their early incarnation as animal skins stretched across logs, drum heads and their technology have leaped forward, beginning with the invention of the first plastic head 50 years ago. Available in thick or thin, single- or multi-ply, coated or clear, with reinforced centers or edges, the range of head types can seem overwhelming. However, when forced to choose, you should remember that moderation is the key: a general-purpose, medium-weight head will usually do the job. For a hard-hitting, loud drummer, a heavier- weight or double-ply head can withstand the pressure. If tuning out overtones and controlling ring is important, then heads treated with sound-controlling centers or edges will help.
Most drum shells are constructed of several thin plies of wood that are glued together and bent into shape, often with the assistance of steam. Much like the tonewoods used in making guitars, the types of wood that a shell can be made of produce different characteristics of attack and tone. Here are some of the most common shell woods:
Regardless of the type, drum shell woods can be stained, painted, or wrapped in just about any finish imaginable.
The scope and characteristics of cymbals are too broad to cover here. Cymbals provide a metallic “soprano” range of tones to complement the “thuddy” characteristics of drums. Here are three of the most commonly used cymbals:
Ride – A medium-weight cymbal that helps outline the rhythmic framework of a song, along with the kick and the snare. Ride cymbals can generally withstand repeated strikes without building up too much of a roar.
Crash – A thin, often small-diameter cymbal that produces an explosive “crash” when struck on its edge. Crash-cymbal overtones normally die away quickly, which gets them out of the way of the rest of the music.
Hi-hat – Actually two cymbals, with one inverted atop the other on a special stand. Hi-hat cymbals are very versatile, able to be played “closed” with the stand’s foot pedal pressed down, “open” with the pedal up, and everywhere in between. Simply pushing down the pedal without striking the cymbals produces a nice “chick” sound.
