I've been building drums for 7 yrs and i believe each profile will resonate differently, slightly changing the frequencies. I do believe that different edge profiles feel different while playing. I have found my favored edge profiles for each drum. This, in turn, has changed my playing + approach to the kit which has changed my sound.

Really appreciated this video. I've been making stave snare drums now for about two years and have been stressing about the correct bearing edge to use on my drums. This has cleared it all up! Thanks! DNH Drums, Sugar Land, TX.

Roundover is the best as it transmits the energy into the shell instead of the rim.

Shape of the bearing edge will have no influence on the amount of “energy” that the shell will be subject to. The head being in contact with the edge is all that’s needed. The bearing edge is a head mute as the various frequencies will be either muted or not muted. The only influence the shell has is its resonant characteristics will control what the head is allowed to do. Denser shell materials will not absorb as much energy resulting in a drum that projects more volume. A less dense shell will absorb more energy resulting in a drum that projects less volume. Shells make no sound.

Have to love this neverending discussion! My 2 cents here : Absolutely no difference between sharp cuts. Makes no difference if its 60-45-30, as is the sharp edge that touches the drum head. Totally different situation with the rounded edge. Theres significantly more surface contact between the shell and the head, resulting in a decrease in attack and a more rounded sound. I have vintage rounded edge drums with 1 ply clear heads that sound much more rounded and mellow that a modern sharp edge drum with a 2ply hydraulic drum head on it. So, as a matter of fact, bearing edges do make a HUGE DIFFERENCE, but not the angle. What makes the real difference is the round vs sharp edge difference.

Bearing edges are important, but not as much as people think. Same goes for the type of material your shell is made of, yes there are differences, but again, not as big as drummers make out to be. That's because of all the marketing hype drum manufactures put out there. 50 years ago you didn't have so much hype, drummers didn't concern themselves with "what type of shells you got" or "what kind of bearing edges do you have". But drums still sounded good, go listen to John Bonham or Carmine Appice, they never talked bearing edges, but damn! did their playing sound good! Don't get me wrong, shell material and it's edges ARE important, and all the different types make a difference in the overall sound, but those differences are nuances, and they all get lost in the mix.

Yes. They absolutely matter. The bearing edge has more effect on the sound than any other factor. When the drums are close miked, eq'd and compressed, yes, none of it matters anymore. The wood, the edge, the head, none of it as the sound is being manipulated for the end result. However, in a small acoustic setting, the differences are 100% audible. Think about it scientifically: the striking of the head is what engages the vibration of the shell. The edge is what determines the amount of vibration from the struck surface (head) that will be transferred to the shell. The drummer in the video linked in the other comment even expresses how he would use each edge type for different musical situations.

Scientifically? Haha! Bearing edges are analogous to guitar frets. 90% of the tone of a vibrating drum head (or a guitar string) comes from the CENTER area. The point where the head contacts the shell, isn't vibrating at all. And the area of the head over the inner slope of the bearing edge is vibrating with such a low amplitude that you simply cannot hear it. Even overtones that you hear when playing a drum are still inches away from the bearing edges. This is why guitar pickups are put near the middle of the vibrating string and not buried in the neck near the frets. The shell's supposed vibration is a tiny factor, the sound you are hearing is the drum head vibrating and the shell acts as a chamber to amplifier the fundamental tone. Its not the other way around. That's why engineers mic the drum head and not the shell! Also in an acoustic setting the acoustics of the environment play a much bigger role than anything else. Overall in a drum the drum head, tuning quality and drum shell SIZE and how you strike the drum matter more than anything else. Shell material type matters less, bearing edge ANGLE doesn't matter at all. The only thing that matters is that the bearing edge is flat, clean and that the shell does not contact the drum head hoop, choking it.

@@weschilton spoken like a guitar player. If all that matters is the head, why doesn't every studio have a $200 SPL kit from GC but with quality heads on it? Why cut an edge at all? Why not just leave it flat? Lastly, no drummer, and I mean NO drummer, hits only the center of the head.

@@cariaddrums He may have a point, but a lot of you have posited that the edge has little to nothing to do with sound and yet none of you have taken to trying to rebut my point on that: if edge and wood don't matter, why do drums even have an edge at all? Why don't studios just get the cheapest crap kit they can find and put good heads on it (since that is what is being posited as the most meaningful to tone)? As for the studio setting, if you had taken the time to read my initial post you would have seen the section where I said in a studio setting where everything is close miked, eq'd, and compressed none of matters as the entire sound is being manipulated through the engineer's board. Where it matters and where it shows is in an acoustic setting. But hey, who cares about context, just read a few lines and write a reply.

NO the air loading has more effect of anything else on the sound and a shell is just a damping system sucking vibration energy from the head (thus affecting vibration of the head therefore the sound) the bearing edge do act on sound but the vibrating shell does merely radiate not more than 10% of the sound

I agree with this, the inner angle has zero influence on the tone... it doesn't touch the head or effect how it vibrates in any way. What does matter concerning bearing edges is the point where it contacts the head. If they are flat and level and there is sufficient space to allow the head to float over the shell, the drum will be easier to tune and resonate.

nope : it does change the mechanical impedance of the bearing edge : the flatter = the stiffer

EXCELLENT commentary …BUT…. find a piano rebuilder that has EXPERIENCE with Steinway, Baldwin, Yamaha and Boesendorfer ( so I don’t remember the spelling) …and SPECIFICALLY …..BRIDGE….. CUTTING …. FOR EACH OF THOSE PIANOS……. The bridge is the “ bearing edge” for all stringed instruments. Ask a Steinway master rebuilder if the bridge design, and cut effect tone and sustain. Steinway even goes as far as minimizing support on the tuning pins claiming that tone production occurs end to end…. AND….. THERE IS AN ADDITIONAL SECTION of string between the tuning pin and the “ capo” ( termination) …. Steinway even adjusts the length of that “ non speaking section” ( Google Steinway duplex scale) claiming again… the WHOLE length of string produces or supports tone… A little here… and a little there….. maybe a big deal…. Maybe not…. Yes… most piano players CAN hear the diff without hesitation… between the above listed pianos….. So….. is it THAT important? Does it change the sound THAT much? Can drummers hear a Yamaha vs Tama vs Pearl vs…….?… head selection, tuning and the drummer’s playing style probably effect the sound a LOT MORE than a WELL BUILT drum…. S another well built drum.

IT….ISSSSSS….from the bearing edge ! But not from the material that DOESNT touch the head…. but rather it …IS…. from the size and shape ( profile) of the wood that DOES make contact with the head. And no bearing edge is “ infinitely razor sharp”… so the variables are, 1) is the bearing edge truly flat / true all the way around the drum 2) is the shell TRULY SYMMETRICALLY ROUND 3) is the top point ( center of contact aka apex ) of the bearing edge truly in the same place per the thickness of the shell. ( #2, #3 and #4 have everything to do with “ tun-ability” 4) is the bearing edge “ relief” ( inside and outside “fall away”) symmetrical 5) is the hoop perfectly round and flat #2,#3 and #4 MATTER… because each and all effect “ total LENGTH “ of the vibrating body.. ( edge to edge/ bearing apex to bearing apex) and/ or from exact center of the head to the bearing apex.) LENGTH OF VIBRATING BODY is one of the three variables that define pitch … length, mass/weight and tension.. ( ok temperature too) If ANY of the bearing edge is not consistent then that portion of the vibrating membrane will be shorter or longer than all the other membrane… and even if ALL tuning lugs and rim locations are perfectly identically tensioned, the variation in length will cause an “ out of tune condition” Steinway pianos went MUCH further than other piano builders to make sure that string lengths were designed and built in to the body of the instrument correctly. Talk with a piano tuner to get their insight into the Steinway duplex scaling. Does ANYONE discuss good techniques for checking drum roundness ? Thx
