The short answer
A bare wooden surface usually creates a firmer, brighter attack, while suede or leather changes the contact friction and often produces a softer attack or easier rim engagement. The exact result depends on the bowl as well as the striker. Controlled A/B recordings are more informative than treating one striker material as universally “better”.
Acoustics / physics
What each surface tends to do
- Bare wood — harder contact, faster energy transfer, a brighter and more defined attack with more upper-partial content. Often engages a reluctant rim more readily.
- Suede or leather — softer, more compliant contact that spreads the impact over slightly longer, giving a rounder attack with less initial brightness. Frequently smoother for sustained rim playing.
Why the difference is real, not a preference
Acoustics / physics
For striking, the contact time and stiffness of the striking surface shape which modes receive energy and how much high-frequency content appears in the attack. For rim playing the effect is more fundamental still: the tone is generated by friction, and published modelling indicates that self-excited modes depend substantially on contact conditions and particularly on the material of the rubbing implement. Changing striker material is therefore an acoustic change, not a cosmetic one.
The consequence for comparisons
Changing the striker invalidates a strict A/B between two bowls unless the striker is deliberately the variable under test. Any honest comparison recording has to hold the bowl, the support, the microphone position, the gain and the striker constant, and change exactly one thing at a time.
Neither is better
Which surface suits you depends on the bowl, the technique and the result you want. A bowl that sounds harsh with bare wood may be ideal through suede; a bowl that will not start singing with suede may respond immediately to wood. This is a reason to own both surfaces rather than to choose a side.
Frequently asked
Should I use wood or suede?
Both, for different purposes. Bare wood gives a brighter, more defined attack and often starts a rim tone more easily; suede gives a softer attack and frequently a smoother sustained rim tone. The best choice depends on the individual bowl.
Which striker gives a softer sound?
Suede or leather. The more compliant surface spreads the impact slightly, reducing the bright initial transient.
Does striker material change bowl frequency?
It does not change where the bowl’s modes lie, but it strongly affects which modes are excited and how prominent they are — particularly in rim playing, where the tone is generated by friction at the contact point.
