[. . . ] However, new heads will tend to stretch gradually during shipping and storage, resulting in a tuning deviation when you receive the instrument. Therefore, please perform the steps below to restore the tuning to the factory setting prior to shipment: 1 The area between the kettle edge and the inner circle of the counter hoop is called the collar. Please make sure that the width of this collar is uniform, as shown in the illustration titled "Correct". Correct Wrong 3 If the heel of the pedal is fully lowered as in Fig. [. . . ] G Pitch of highest sound lower than tuning note ¡ Go to step 4. I Standard Tonal Ranges for Yamaha Timpani 32" (81cm) 29" (74cm) 26" (66cm) 23" (58cm) 20" (51cm) Keep the heel of the pedal fully lowered during the tuning procedure (steps 2 through 7 below) if not specified otherwise. 2 Strike the head and check the sound. The standard striking point is shown below. The standard striking point lies at distance B from the kettle edge, which corresponds to 1/4 to 1/3 of distance A (distance between kettle edge and center of head). 4 Striking point Pedal G Sound lower than tuning note ¡ Go to step 3. G Sound higher than tuning note ¡ Loosen tuning bolts by an equal amount in the order shown in the figure of step 5 on page 5. Tighten the other bolts little by little (by about 1/ 16 to 1/8 of a turn) until the sounds at the corresponding striking points match the pitch of the highest sound. Please note that tightening of one bolt will also raise the pitch at the neighboring and opposite tuning bolts. Thus, after tightening the tuning bolt with the lowest sound, first reconfirm the sound at the other tuning bolts before tightening the tuning bolt with the next lower sound. While alternately tightening the other bolts, do not touch the tuning bolt with the highest sound (reference pitch). Loosen all overtightened bolts according to the procedure described in step 3. When the pitch is approximately the same at each bolt, repeatedly depress the toe and heel of the pedal several times. 5 6 Adjusting The Sound Of Your Timpani x Pedal Adjustment 6 7 Repeat steps 3 through 5 until the pitch at each bolt is exactly the same. G Sound lower than tuning note ¡ Tune the instrument by tightening all tuning bolts by an equal amount (max. G Sound higher than tuning note ¡ Tune the instrument by loosening all tuning bolts by an equal amount (max. 1/16 of a turn) according to the procedure described in step 3. After depressing the toe and heel of the pedal, turn the spring tension adjustment bolt as described below. G Heel moves up when releasing the foot from the pedal after depressing the heel, or heel feels heavier than toe ¡ Turn the spring tension adjustment bolt to the left (counterclockwise) G Toe moves up when releasing the foot from the pedal after depressing the toe, or toe feels heavier than heel ¡ Turn the spring tension adjustment bolt to the right (clockwise) Turning the spring tension adjustment bolt is performed using the timpani key. Do not turn by too many full rotations at once, but re-check the adjustment state every 2 turns by depressing the toe and heel of the pedal. Note 8 Operate the pedal as described in step 5. (If the pitch changes, repeat from step 7. ) The instrument is now tuned to the lowest sound (note) of its tonal range. Depress the toe of the pedal to change to a higher pitch (note). Do not loosen the spring tension adjustment bolt by more 3 rotations at a time, as the toe of the pedal tends to drop abruptly after a specific point. under the pedal. 9 After tuning, perform x Pedal Adjustment and then c Tuning Indicator Adjustment. Caution Spring tension adjustment bolt Spring Timpani key G Pedal balance spring mechanism Your Yamaha pedal timpani is equipped with a unique pedal balance spring mechanism (a coil spring counteracting the tension of the head) which allows you to freely change the pitch (note) of the instrument at an instant. [. . . ] For precise tuning, refer to the section "Adjusting The Sound Of Your Timpani" on page 6. 4 Caution Never put your hands etc. under the pedal. 2 After removing all tuning bolts, mark the pedal side of the hoop with cellophane tape etc. At this time, be careful not to lose any of the tuning bolts and prevent dust from adhering.
