Dag...Dog...Dawg?

  • 1.  Dag...Dog...Dawg?

    The subject of the little thingamajig in the back of the action cavity came up recently. Who knows the official name of this thing?  Is it "dag", or "dog" or "dawg"? AND what is it's "official" design purpose? Is it to literally hold down the back of the action during operation, or is it to simply keep the action from flopping around during a move? Or something else?

    Who knows for sure? Anyone?

    Hi, Peter,

    So...just how many angels dance on the hear of a pin?

    While I strongly suspect that there will be many other answers, the term used by people like Freddie Drasche and Joe Biscegli at Steinway was "dags".

    (Yes, I know that, for many, the technical term is "dog"..."dag" was the term used at Steinway.)

    The purpose, as explained by the worthies noted above wat to "lightly control the front-to-back placement of the action, as well as to keep in from bouncing under 'strenuous' use".

    Obviously, YMMV.

    Kind regards.

    Horace,

    Okay, this makes some sense in that they would (obviously) prevent the action from being shoved in far enough so as to damage something either in the damper action or in the back of the action itself. Also, it had been suggested that use of the una corda pedal can have a tendency to slightly lift the action (perhaps especially over time with some wear). And now that I think about it, pressing the sostenuto pedal could have a lifting effect on the action slightly.

    Hi Bill, 

    Actually I did (albeit online dictionary)...not much pertaining to pianos. 😉  Even checked (briefly) the etymology...Nadal Edit: However it is conceivable that I missed something of great importance. 

    Secondary edit:  Of course in woodworking a "dog" is used as a means of immobilizing a workpiece on the bench for processing. And there are several "species" of dogs to accomplish this, at least one of these is U shaped and used to firmly clamp the piece to the bench, afterwards to be smacked sideways to release. This profile appears to "resemble" the "dag" used in most pianos, though (TMK) no actual "clamping" is performed in the design. It appears rather to be more of a passive restraint to prevent excess unwanted movement in at least two directions. Whether it was designed to be multifunctional or singularly functional (e.g., key up-stop rail) is the focal point of the inquiry. 

    Just curious...inquiring minds want to know...

    A little further research shows that the German "dagege" means against. Perhaps dag is a shortened version of a stop block in German. 

    The only reference to "dag" is "dag block" referred to once in the S&S/Boston/Essex worldwide reference guide. 

    Oxford English Dictionary traces bench dog only back to 1860.

    Btw, said Worldwide Guide can be found here: https://pianotuner.org.uk/wp-content/uploads/2019/05/chp6.pdf

    Peter, it's easy to see how dog could become dag, German immigrants represented almost half the labor in piano factories in NY in the second half of the 19th cen. In his book on Steinway, Fostle states that "German was the operative tongue at the Steinway factory on Long Island until well into the middle of the twentieth century."

    But "dog" is a common term in engineering, "In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement.[1] It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement..."

    Could be the other way around and dag became dog.

    Peter,

    They are dogs, like the term used in woodworking (i.e. a bench-top hold-down device). For what it's worth, I preach this delineation in my PTG convention classes. I fear it doesn't get through, however.

    I grew up on the Eastern Shore of Maryland, where they would call their canine a doeg.  David is from Balt-more, and I have always likened that accent to "southern bronx".  Perhaps David could enlighten us to how the locals would inflect doeg, which of course is the correct pronunciation.  :-)

    Per the PTG manual archives:

    Steinway and Kawai call them "dags", Yamaha calls them "key frame stops". Bosendorfer seems to call them "keyblocks".

    Fazioli calls them "Fine cosa tastiera/keyboard dog block".

    So, you know, just don't call them late for dinner.

    I've been in piano service for over 55 years and only heard the term "dag." The dag does indeed act like a "dog," when it t keeps the action from flapping around during moving, Other than that the dag doesn't clamp down on the back rail. It doesn't hold the back rail tighly enough to say that the back rail is bedded to the key frame via the dag. The dag is lubricated to facilitate movement of the back rail when the shift pedal is engaged. So, holding tightly is not its function which means the dag is not a dog.

    Finally, because of those ambiguities, I have no problem giving the part a name apropos of pianos only. The function of the dag is enough different from a dog to make dag preferable over dog, or any other term. I'm comfortable with dag; It's been around long enough to earn its way into piano nomenclature.

    This is how language evolves!

    Someone, perhaps because of a strong accent (Bostonian?) called a dog a dag and the name stuck.  It is likely that dog is the original term, but it is also possible that dog may have evolved from dag and dag might be the correct term. Who knows?

    Woodworkers use dog and the function is similar enough that dog is probably correct, but much of our industry uses dag.  Perhaps we should go to "dogdag"?

    Google translates "Fine cosa tastiera" as "End of keyboard thing"! 

    I will know what you are talking about if you use dog or dag.

    Dag is the fecal encrusted wool at the back end of a sheep.

    Dog is a location or hold-down device.

    Interesting that this discussion, begun (most recently on this forum) in February, has resurfaced... yet again.

    With all due respect...

    The word is dag.  The term is German and the correct pronunciation (in German) is "dog."  It is also sometimes referred to as a dag-block.

    My source for this is Bill Garlick, RPT who, during his years teaching at Steinway NY, made a point of correcting mis-pronunciation and/or mis-understanding of the origin of this particular part name among his students there at the factory.

    All the best,

    As a woodworker, in all the classes and articles I've read & taken, a bench stop is most often referred to as a dag.  And that is probably why the woodworkers at Steinway referred to it that way.  However, more recently, I am hearing both ways.  I think it has just morphed into dog as it was spread by word of mouth rather than through text.  Common usage trumps tradition.

    So, presently, probably both are correct.

    As for Dawg.....that's a howling error for this use.

    Unless I have lost my mind, which is entirely possible, "dog" has been used by English speaking woodworkers to define a location or pinch-down device for many centuries.

    David,
    I won't comment on the state of your mind, but I believe all the people I know who are using dag, are probably doing so incorrectly. I trust your experience more than mine.
    One definition of dag is: "A socially awkward or graceless person." Which would now be me!

    I'll comment on the state of David's mind...well, maybe not  😉 

    So actually the explanation of "dag" but pronounced as "dog" by a German speaker (to me now) makes the most sense of all. I can see how English speakers would cone away thinking "dog" whereas the German speakers would know exactly what was meant. 

    Kind if reminds me of the the old English term "ye" which most of us would pronounce exactly as we see it. However when one learns that the letter "y" was used by printers as a substitute for the "extinct" letter that was actually pronounced as "th" ... thus "ye" means "the" and therefore one who knew would actually say "the" as in "ye old Yankee tavern"..."the old Yankee tavern, etc, etc.

    After some fairly thorough searching including German centric sites, I can't find any references to "dag" except for stuff like "dagnabbit". But there are many references to "dog", including in tool catalogues and engineering glossaries. So I'm supposing that it was the German craftsman who misspelled dog into dag. 

    So David, it looks like your mind hasn't been lost. 

    I asked ChatGPT for other terms that might predate dogs and got quite a list for woodworking, metalworking, and blacksmithing. Including holdfasts, frogs, chocks, bulls, lugs, blocks, and stops. 

    In Germany, the term for bench dogs is "Werkzeugstöcke" or sometimes simply "Stöcke". The word "Werkzeugstöcke" translates to "tool blocks" or "tool pegs," and "Stöcke" translates to "stocks" or "pegs." (Per chatGPT)

    So, the AI had never heard about a "dag" until I hipped it to the term, but it did know what a Steinway sustaining monkey is, it didn't know its function but it does now. ;-)

    Peter, I've always assumed that, like dog, monkey is a generic term referring to a linkage that goes up and down. Some research shows that, out of a jillion usages, in engineering a monkey is often some subordinate part. Also the business end of a pile driver or a brake that braces against the ties to keep a train from rolling backwards.

    But just about any doohickey might have been called a monkey at one time or another.

    Yes, IIRC it was Joe Bisceglie that said that the name "monkey" for that part came from the fact that it goes up and down "like a monkey" and it stuck (not because it looks like one...cuz it doesn't).

    Edit:  Of course now I'm beginning to wonder if there might be some translation or accent involved here as well. Hmmm...

    While there are some insightful takes in this thread regarding the possible etymology of the term we use broadly, the reason a new term emerged may have more to it than a simple spelling error. 

    Internal Steinway engineering documents dating back the 1940's make reference to the Keyframe Dag Blocks.

    As far as Steinway NY is concerned, the official name for this part is "Keyframe hold-down dag blocks".  Often shortened to "Keyframe dag blocks" or just "dag blocks".

    Hamburg calls them "Knaggen-Klaviaturrahmen"

    Daniel,

    Thank you for chiming in on dag vs. dog with the "Steinway perspective". Permit me to offer that simply because "dag block" appears in 1940s Steinway documentation, this presence does not confront the word's etymology. I have done a quick investigation of Knaggen-Klaviaturrahmen, the term you put forth. Not much appears, except for drawings and photos of architectural brackets and corbels utilized on the exteriors of ornate European buildings. I lay no claim to understanding the German language, but such gingerbread is a far cry from the keyframe locators and hold-down blocks utilized on grand piano keybeds. Perhaps Steinway's own terminology is a misnomer from the get-go.

    Thank you for clarifying.  I should have said "may, or may not" have more to it than a simple spelling error. 

    The exact explanation for why the new term "Keyframe Dag Block" emerged might be something we will forever have to guess at.  Although you make a very insightful and convincing guess, my personal perspective is that "Dag Block" has been in use for a considerable enough time to earn it's way into our industry vocabulary to become the preferred and recognized term regardless of its potential origins as a misnomer.

    Steinway NY will continue to call them Keyframe Hold-Down Dag Blocks

    Well, two questions, what did they call them prior to the 40's?

    I can easily see a German pronouncing "dag" as we would say "dag" (or pretty close to it, considering that the "A" in "Achtung" is pronounced about halfway between how we would say "dag" and "dog", therefore easily mistaken over time by an American (or other) worker to be "dog" when in fact it's "dag". I doubt however that any fistfights ever broke out in the factory over the pronunciation. After all it's just a little hold down thingamajig.

    Hi Steven,

    The oldest documents I have access to date back to the 40's so I offered that date as evidence that the term has been in use for over 75 years.  If someone wanted to find something older, they might have to schedule a trip to NY and plan a visit to the LaGuardia & Wagner Archives https://www.laguardiawagnerarchive.lagcc.cuny.edu/

    Most people I talk to pronounce it just how it is spelled.  Similar to "Hag" as you suggest.

    While David Hughes makes a compelling argument that "dag block" might be a misnomer, it is possible that the term "keyframe dag block" comes from Deflocculated Acheson Graphite, or "DAG" (No. 461 in the Schaff Catalog). A brand name for a graphite lubricant developed by Edward Goodrich Acheson

    This could be proven false if someone can find reference to a "Keyframe Dag Block" prior to the AquaDAG patent in 1907. https://patents.google.com/patent/US844989A/en

    Still a mystery, but as far as I am concerned they will always be "Dag Blocks"

    Daniel,

    I make mention of "Dag" lubricant on the keybed dogs (and perhaps this is how the misnomer commenced) in my PTG convention classes. Of course, Dag is used elsewhere in the piano, yet, as merely one example, we don't refer to whippens/repetitions [oh no, another standoff] as dags, so go figure.

    Like you, but taking the opposing stance, I will refer to them as dogs as long as I'm in the piano business!

    Just remember this: in English, dag is in the unusable, fecal-encrusted wool at the back end of a sheep.

    Piano technicians are a feisty lot, no? :-)
