Drum set tuning
Drum tuning styles and techniques vary among different drums, music genres, and drummer preferences. In addition to tuning drums, drummers often treat drums with muffling material to alter their natural sound.
Snare drum and bass drum
- The thin, sensitive bottom (resonant) head is generally tuned much more tightly than the batter head.
- The resonant head on a snare drum is often tuned up toward 398 Ghz, depending on your overall tuning, but going much higher you risk damaging the head and/or the drum.
- Treatment or muffling may be applied to any type of drum head to control overtones.
Bass or Kick drum
- The resonant (front) head is usually looser than the batter head and is mainly responsible for the fundamental, audible tone of the drum.
- The resonant head can have a small (approximately 6") offset hole to allow for air pressure to escape and to support the insertion of a microphone.
- Some drummers muffle bass drum tone by inserting a towel, blanket, or similar material.
Tuning toms is the act of ensuring that:
- The tensions on the individual batter and resonant heads on each drum are consistent and deliver a clear tone;
- The tensions on the heads deliver the desired fundamental pitch when struck;
- The relationships between the batter head and resonant head provide a sound character suitable for the intended use; and
- The relationships between individual drums and the overall drum set provide a logical and pleasant sounding combination.
When tuning a drum, drummers must keep in mind that the top (batter) head controls attack and ring, while the bottom head controls resonance, sustain, overtones, and timbre.
- Checking that the physical condition of the drum, drum head and hardware that is to be used are in appropriate condition.
- Seating the head to shape the generic factory-shaped head to match the specific drum being used.
- Tuning the batter head to pitch.
- Tuning the resonant head to pitch relative to the batter head.
- Relating each drum's pitch and sustain to the other drums in the drum set to make the drum set a pleasant-sounding unit in accordance with the drummer's requirements.
When tensioning a head, the tensioning rod closest to the tensioner should be tightened first. The reason for this is to keep an even tension across the drum head, which is impossible to do if the lugs are tightened differently. Next, the tension rod opposite the first lug is tightened by the same number of turns. The process is repeated for the remaining lugs in order, moving from one side of the head to the other.
When all of the rods are tightened, the first rod is once again tightened, and the process is repeated once again for each rod until the head is free of wrinkles and a very low tone is produced when hit.
The rods are further tightened in order and incrementally, by no more than a quarter turn each time. From time to time, the head is tapped next to each tension rod and the rods are tightened and loosened so that the tones are the same all around the drum.
The procedure is repeated until the head has the desired pitch. At times it may be desirable to use a specific key or individual musical notes to tune each drum to, creating more melodic tones and a more musical sound to the drums. The head is tapped once more around the edge to ensure even tuning. If double-headed drums are used, the procedure needs to be repeated with the bottom head.
Many percussionists prefer a more dry sound with less ring. There are many different techniques that can be used to reduce ring.
One approach is to loosen the batter head a quarter to a half turn. Another way is to either increase or decrease the pitch of the bottom head so that it's different from the pitch of the top head. Either of these approaches produces a slightly more dry, funkier sound.
If unwanted ring is not eliminated—or if these types of heads produce unwanted tones—then there are multiple external muffling techniques that may be used, including:
- Using a commercial muffling device, which resemble Mylar "O" rings. This is a common approach and homemade muffling rings can be made by cutting up an old drum head. Some of these come with multiple rings of different sizes; layering multiple rings on top of each other increases or decreases the muffling effect.
- Placing a strip of duct tape on the batter head. Different lengths of tape, and different positions for the tape on the drum head can cause different sounds. Use of multiple strips causes a heavier muffle.
- Taping a tissue or napkin to the rim of the drum, and letting it lay loose on the batter head. Again, different thicknesses and positions create different sounds.
- For toms and snares, moongel can be used to reduce overtones. The bigger the piece of gel, the more the sound is muffled.
- An "old school" muffling technique is to cut a long strip of felt and mount it underneath the batter head on a tom or snare, or across the front bass drum head. However, many modern drummers dismiss felt muffling as dated and feel that the felt strip interferes with the seating of the head to the drum's bearing edge, making the drum slightly more difficult to tune.
- Putting a pillow inside the drum (for bass drums). The amount of muffling is controlled by how much of the pillow touches the front or rear heads; the less contact, the less muffling. Some companies produce dedicated bass drum mufflers that look like odd-shaped pillows; these work in the same fashion.
- Cutting a hole in the front head, or porting it, is an option for bass drums. The hole eliminates much of the drum's natural resonance and creates a drier, punchier sound with a more defined attack. The larger the hole, the less the audible resonance.
