[. . . ] Serious injury can result if fingers or feet become pinched. Transporting/Setup • Never place the timpani on unstable surfaces such as an unstable riser or sloped surface. • When rolling the timpani on its casters, grip it by its frame and move it only on smooth, flat surfaces. It may be difficult to stop the instrument which can cause injury or damage. • If the timpani must be carried, do so with two or more persons, make sure to grip the timpani by its frame. • Except for when moving the instrument, always engage both caster brakes. [. . . ] Please perform the following steps to check and, if necessary, readjust your instrument. 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” . 2 Fully depress the heel end of the pedal. While holding the pedal in this position, use the supplied tuning wrench to tighten the tuning bolts one by one ¼ of a turn (90°) in the order shown in the illustration below. It is very important that all tuning bolts be turned the same amount. [Correct] [Wrong] KettleEdge Counter Hoop Collar Kettle Edge Counter Hoop Collar If collar width is not uniform, fully depress the heel end of the pedal. While holding the pedal in this position, realign the head and hoop as shown in the “Correct” illustration. Tuning Key Caution Never place your fingers or feet into the spaces underneath the pedal, the base portion of the instrument, or between moving parts such as the casters. Serious injury can result if fingers or feet become pinched. 26” 27” 29” 32” , , , 20” 23” 24” , , 3 Take your foot off the pedal. • Heel still moves up Repeat steps 2 through 3. g • Heel stays down Go g to step 4. 18 Initial Preparation 4 Put your foot on the pedal and fully depress it in either direction (toe and heel). • Heel feels lighter than toe (*1) Head is too tight and should be loosened. g Keeping the heel of the pedal depressed, loosen the first tuning bolt by 1/2 turn and then re-tighten it by 1/4 of a turn. Perform this operation for all other tuning bolts in the order shown in step 2. Repeat this procedure until proper head tension is obtained then go to step 5. 6 Tap the head lightly with the mallet. The standard striking point is shown below. The standard striking point lies at distance B from the kettle edge, which corresponds approximately to 1/4 to 1/3 of the distance between the kettle edge and the center of the head. Striking point Pedal As the toe of the pedal is pressed down, the pitch is raised. • Heel feels heavier than toe Head is not tight enough. Keeping the g heel end of the pedal depressed, tighten each of the tuning bolts another 1/8 (45°) turn in the same order as in step 3. Repeat this procedure until proper head tension is obtained then go to step 5. For details on precise tuning refer to “Adjusting the Pitch” on the following page. 5 Move the pedal into an intermediate position, as shown below, and remove your foot from the pedal. Confirm that the pedal stays in this position and does not move. As the head will stretch over time, readjustment should be performed periodically (starting with step 4 ). • If the pedal remains in the same position adjustment is complete. Loosen the head usg ing the procedure described in step 4 (*1). 19 Adjusting the Pitch When using the timpani for the first time, be sure to set it up according to the instructions of “Initial Preparation” on pages 18 and 19. n Head Tuning 1 Tuning is adjusted on the lowest note of the timpani. For this reason, the heel of the pedal must stay fully lowered during the tuning procedure. The pitch of the lowest note (and the tonal range) depends on the size of your timpani. For example, as shown in the chart below, the lowest sound of a 29” timpani should be tuned to F. When tuned properly, your Yamaha timpani will play throughout its full tonal range with balanced tension in the paddle. When loosening the tuning bolts, always loosen them by double the desired amount, and then return (re-tighten) them by half. When the sound lies within 1 halftone below the desired pitch after loosening the tuning bolts (repeatedly, if necessary), proceed with step 3. 3 Lightly strike the head with the mallet about l Standard Tonal Ranges for Yamaha Timpani 27”(69cm) 32”(81cm) 29”(74cm) 26"(66cm) 24”(61cm) 23"(58cm) 20”(51cm) 2 inches (5 cm) from the kettle edge at each tuning bolt. • Pitch of the highest sound is higher than the tuning note (*2) Loosen the corresponding tuning bolt by g about 1/16 to 1/18 of a turn. First loosen the bolt by double the desired amount, and then return (re-tighten) it by half. [. . . ] Also, never place your fingers or feet in the space under the pedal, around the base, or the moving parts. Spring tension may cause the pedal to suddenly move posing a great danger. 6 Adjust the timpani as described on page 18 2 Loosen the tuning bolts on opposite sides of “Initial Preparation” starting with step 2. For precise tuning, refer to the section “Adjusting the Pitch” on page 20. the timpani and remove the head. We recommend that you mark the pedal side of the hoop with a piece of tape, etc. [. . . ]
