Replacing drum heads is an important part of maintaining
both the aesthetic appearance, and the acoustic performance
of the drum. Over time, the drum head develops concavity

from the repeated strikes of the drum sticks. The sound
quality and the responsiveness decreases as the drum head
deforms. Although some musical experience is useful in
tuning the drum after replacement of the head, little
technical ability is needed to perform the basic steps. This
task may take up to 30 minutes the first time it is performed.
These instructions are intended for someone with little
background working with drums. Tuning a drum is a skill
that is acquired with practice. These instructions will lead
to the development of this skill. After some practice, this
task can be completed quickly and easily.

Before you start
        Gather all listed Materials:
            □ New drum head
            □ Drum key                                           Photo 1. Snare Drum with 8 tension rods and a drum

            □ Drumstick
            □ Soft cleaning cloth
A. Removing the old drum Head
    1. If the drum is on a stand then disassemble the drum
       from the stand.
    2. Place the drum on a table covered with a blanket or a
       carpeted floor that will allow easy access to all the
       tension rods. The level surface underneath the drum
       protects the shell while turning and pushing on the
       rods.
    3. Choose one tension rod to loosen. For example, refer
       to #1 in Photo 1. Any one may be chosen as the first      Photo 2. Loosening a tension rod with the drum key.

    4. Loosen the rod with the drum key in a counter-
       clockwise direction—loosen enough so that it can be        Note

       being subjected to needless uneven stress. (See Note
       for an explanation of the importance of
       loosening in opposing pairs).

                                                                                                                         1
  7. Finish loosening the rods by hand. Remove them
     from shell housing and leave them in the rim. The
     order is not important here. Refer to Photo 3.
  8. Remove the rim and tension rods by lifting it off the
     drum (Photo 4 (a)). It will lift easily. Wipe the rim
     and the rods clean of any wood splinters with a soft
     cleaning cloth.
  9. Remove the old drum head (Photo 4 (b)) from the
     drum and clean out the inside of the drum. A simple
     wipe-down cleaning with a soft cloth is sufficient to
     remove the dust and wood splinters.


B. Installing the new drum head.

  1. Seat new drum head over drum shell. Line up shell
     and drum head logos for aesthetic appeal. Make sure
     there is nothing between the head and the shell.
  2. Place rim over drum head, align tension rods and
     ensure there is nothing between the rim and the head.
  3. Firmly hand-tighten the tension rods in any order
     until it is hard to turn them any more.
  4. Follow the tightening pattern shown below in Photo
     5 and tighten each rod one full (360 degree) turn.
     Proceed around the drum following the pattern from                     (a)                   (b)

                                                                 of the drum head while applying tension.

           warping the drum head.


  5. After the drum head is tightened onto the shell, strike
     the drum with a drumstick and listen to the pitch.
  6. If the pitch is near the desired final pitch then
     proceed on to tuning, if not then go to step 8. The
     desired pitch is solely dependent on your preference
     and application.

    7. If the pitch is too low then repeat steps 5-7 with ¼
       clockwise turns on each tension rod, instead of full
       turns. If the pitch is too high then turn counter-
       clockwise.


C. Tuning the localized drum pitch
Although a drum may have the overall pitch desired, it may
have different pitches in localized areas of the face. This is
due to uneven tension on the surface of the drum head from
the tension rods. The following procedure will allow you to
attain a uniform pitch on the whole drum head surface.

    1. Place a finger on the center of the drum as shown in       Photo 8. Tuning the drum by checking the pitch
       Photo 8. Just rest your finger and do not apply much               between a tension rod and finger.
       pressure.
    2. Tap the drum with a drumstick midway between
       your finger and one of the tension rods (Photo 8) and
       listen to the pitch.
    3. Next, tap the drum midway between your finger and
       the opposite tension rod (Photo 9) and listen to the
       pitch.
    4. If one pitch is lower than the other, the tension rod
       on that side needs tightened. Test each side again
       and repeat until a uniform pitch is achieved.
    5. Continue around the drum in this manner, checking
       the tension rods in opposing pairs, until all the
       pitches are the same.
    6. Remove the finger and tap the drum to check overall
       pitch.
                                                                  Photo 9. Checking pitch between opposite tension rod

small adjustments to the tension rods until the desired tone
is acquired. If the overall pitch is too high, then the tension
rods are too tight and they need to be adjusted counter-
clockwise. On the other hand, if the pitch is too low, then
the rods are too loose and they need to be adjusted
clockwise. It is important that every part of the drum has a
uniform tone.
The replacement of the drum head is complete! Enjoy the
new and improved sound. The new head will be more
responsive and the sound more crisp. Regular care and
maintenance, such as changing the drum head, will keep the
drum in good condition and allow peak performance.
