Move
the dryer around constantly in a circular motion, so that you will
be heating the outer perimeter of the entire head without stopping
anywhere. Check the temperature with your hands; you’re just
trying to make the plastic warm, not hot. If it feels warm, then
you’re ok to stop. You can also try this trick I figured out:
while circulating the dryer, tap constantly with your finger on
the outer edge of the head (visible in Photo 3). When you hear the
pitch drop, you’re done. This process doesn’t take very
long, and if you do it too long, you can easily melt the plastic
and make the new head unusable, so keep in mind that it’s
safer to under-heat than to over-heat. If done properly, the new
head is instantly seated and can be tuned right away.
Loosen
all of the tension rods so that the head is back down to no tension.
Tighten the rods now with your fingers until you feel that the tension
rods start to make contact with the hoop (this is referred to as
“finger-tight”). Then, using either two keys at a time
on opposite sides of the drum, or a single key going to opposite
tension rods, turn the keys by a half-turn, and repeat this for
the other rods. Listen for pitches from the outer edge of the head,
and try to make sure you hear the same pitch all around. This indicates
that the head is pretty evenly tensioned, which makes tuning easier,
and makes the drum speak freely. Another way is to use a device
called the “Drum Dial,” which is a small device that
sits on the drumhead and measures surface tension. It can really
cut tuning time down, especially in a noisy environment where you
can’t hear pitches, or if you’re in a hurry, or inexperienced.
Drum torques are devices that measure the amount of torque on each
of the drum’s tension rods. I DON’T recommend these
because it’s not only possible, but also quite common, to
have a head that is evenly tensioned, yet have tension rods with
all kinds of different torque readings on them. It’s the head
tension that matters, not the rods.
Every
drum has a range in which it sounds good. Your ears will tell you
if you’ve tuned the drum too low (it will sound floppy and
not produce a clear tone) or too high (it will sound boxy and choked).
When a drum is tuned in a place that it’s happy, you’ll
be able to hear a nice, distinct, clear tone that resonates freely
and doesn’t require a lot of effort. In other words, it should
“speak” well whether you’re playing quietly or
loudly. These are very ambiguous terms, but the only way to fully
understand all of these principles is to experiment. A good way
to start the process of getting familiar with your drum and what
it’s capable of is to start by tuning the heads at the lowest
pitch that they will produce a clear, undistorted tone while tapping
at the edges. You can make changes from there to see how your drum
reacts to different tensions. I won’t go into the whole discussion
of Bob Gatzen’s “Tuning Regions” here, but I do
recommend that you go out and buy his video, “Drum Tuning
and Design.” It has a TON of information packed into it, and
you’ll be able to tune your drums for any style of music or
personal taste.
Now,
a question I get asked at the store often is: “Should both
top & bottom heads be tuned to the same pitch?” The answer
is: It depends on your style and desired sound. There are three
possibilities. The first is to tune the top and bottom heads to
the same pitch. This will give your drum maximum volume, tone and
sustain. This is useful if you want an open, singing quality from
the toms. The second: tune the top head a little tighter than the
bottom head. This will enable you to keep a lively stick action
on the drum, but the sustain will be shorter and the volume somewhat
lessened. At lower pitches, the drum will also have a “pitch
bend” effect, and the note will dip after the initial attack.
The third: bottom head tighter than the top. This will give the
most attack, and the drumhead will feel soft and yielding when you
play. It will also give you shorter sustain, lower volume, and pitch
bend at lower tunings. The latter two methods work well with busy
playing styles and close miking, although remember that as long
as it sounds good and feels comfortable, then do it.
Another
question: “Should the drums be tuned to specific notes?”
Drums are unique in that they aren’t really pitched instruments;
their function is in the realm of rhythm and color. They also have
2 vibrating membranes, which makes their sound extremely complex,
and difficult to get to a specific note (tone). What you should
try to shoot for is a good relationship of intervals (differences
of notes/tones) between all the drums, while keeping a consistent
“flavor” with all of them. In other words, for example,
one tom shouldn’t sound floppy while the rest sound full and
resonant just for the sake of keeping consistent intervals across
the whole set.
If
you have a large, multi-tom set, you can afford to go for smaller
intervals between the “notes” on your toms. For smaller
sets (four or five drums total), go for larger intervals. With just
two toms tuned quite far apart, you can really cover a lot of sonic
space.
After
a while, when the heads start to get a little worn, or if you decide
that you need to change the tonality for a different gig, you can
still use them if you do some maintenance tuning. Plastic distorts
over time as you hit it, so if your toms start to sound a little
unpleasant, start with one tension rod, and loosen it completely
(referred to as “dumping” it). Then re-tension the rod
back to its former pitch. Do this on a couple of rods until the
drum’s sound improves. If you want to tune higher, simply
tension the drum higher. If you want to tune lower, dump the rods
and then tune up to the desired pitch. Remember: you should always
tune up to a pitch, not down. If you can’t get a good sound
out of an aging head, no matter how many times you dump lugs and
re-tune, then it’s time to replace it.
DON’T
FORGET THE BOTTOM HEADS! Even though you’re not hitting
them, they get old & tired, too. They should be changed at least
every third batter/top head change (unless you’re a basher
and you’re changing the batter heads once a month). Speaking
of bottom (resonant) heads, they are a large part of the toms’
overall sound. The attack characteristic of a drum is governed by
the batter head, but the sustain after the attack is influenced
greatly by the resonant head.
Here’s
a quick guide to help you find the heads you need to give you the
sound you want. Bear in mind that this is a short list, and it doesn’t
cover all the different head types available, so check with the
(hopefully) knowledgeable people at your local drum/instrument shop. |
