Timpani, Part One

Posted by Chindi on 1/13/2021, 9:22 am

One of my timps has a pedal that won't stay in place. When we push it down to tune higher, it immediately goes back down to low. My question is: On the side of the foot where the pedal is attached, there's a bolt that seems to be attached to two pads on either side of a rod attached to the pedal (JEEZ, I hope that made sense). Anyway, can I adjust that bolt to help hold the tuning??

Also, please see Part Deux.......

Hey Folks,

THANK YOU ALL so much for your advice and help. As it turned out, the drum in question was not tuned correctly. Once I fixed that, we were good to go.

Thanks Again,
C

A timpani is basically 2 springs that need to be in balance.
Be aware that you will need a different drum key for timpani. Your local music store should have them.

In all my years as a repairman, the answer to this was 100% of the time, the head is too low. Tighten up to correct range and you should be good.

Don't adjust bolts to fix that. Your timpani isn't holding pitch because the tension rods aren't correctly adjusted and/or the head is improperly tuned. Fix the head first and the adjustment "knob" second. Check Youtube for instructions.

Don't start turning things without knowing what you're doing.
Ludwig timpani I assume? This is a balanced-action pedal, which means the pressure from the head should be balanced against a spring in the pedal itself. If it is not staying in tune, a very likely problem is that the head itself is not tuned to the right range. Check that first. The ranges of the drums are
[ 32: D-A. 29: F-C. 26: Bb-F. 23: D-A ]
Some other brands may give you a range of a 6th rather than a 5th, but the range is very similar.
If the drum is actually in the correct range then the spring tension is off (somebody decided to turn the acorn without knowing what it did). Find someone who knows what they are doing to walk you through it. You shouldn't need to use the screw with the 'break pads' if everything else is working.

Generally speaking, when timpani pedals won't stay in place it is due to the base pitch of the drum not being correct. With the pedal all the way down the drums should be:

32" = D
29" = F
26" = A
23" = C

If this is correct the pedals should stay in place. If not, it will require additional adjustments, but I would HIGHLY RECOMMEND not turning knobs or messing with other adjustments if not necessary.

Yes, BUT, make sure the drum is tuned to the correct starting pitch.
With the pedal all the way at it's lowest point tune the drums to the following pitches:
32 In Drum-D (below the bass clef), 29in drum-F (below bass clef), 26, A (first space bass clef), 23, D (middle line bass clef).
