Stradivarius and Guarnerius Violins: The curve of the Back and the Mystery of How it's Done so Well.

[@garymcaleer6112]

Throughout my career, I played my '72 Sergio Peresson. A copy of a Guarneri, it was before he increased production with luthiers building his instruments, and Sergio would do the assembly and staining. A powerful and lovely sound. I sold it when my wife got sick. One day, I hope to find a similar quality. When that day comes I will contact you.

Hi Kevin. I am neither a violinist nor a violin maker, however I am so appreciative of your videos that I always look forward to the next one. I believe it's because of some common thread we share both musically and spiritually. Thanks for your ever engaging and informative content.

[@charlesblithfield6182]

Some of your comments remind me of a course I took in film making many years ago. The instructor repeatedly emphasized that auteur directors left not one frame of the film to chance or happenstance. Every element of the film, from composition to lighting, sound and music, everything, including credits, was necessary to create a masterpiece of filmmaking. Directors such as Kubrick and Hitchcock are exemplars of this philosophy and I take it to heart when making a violin.

i never liked antiquing in vioilns, yet your violin is so gorgeous! the little specks of yellow that radiates through the rich brown varnish on the belly is just very tasteful, subtle..back is a little more bold for my liking, in my opinion something like the top would have been more suited, but then again back wears down more than the belly. i am just in awe of your knowledge and more importantly the quest for the secrets and sharing with us! waiting eagerly for the next episode. regards from new zealand.

Antiquing is truly a matter of taste, and they do come across differently in person, and in different light. Thanks for watching and for your comment!

[@kiwiviolin941]

@@kevinleeluthier quick question, doesnt the difference in size of the upper and lower blocks (the ones glued on to to the form) contribute to this slight curve?

[@kevinleeluthier]

The difference in the bock heights creates a "taper" to the instrument, which is a different feature than the "curve," though this taper does make the curve visually appear more than it would otherwise. Thanks for the comment!

Could you please share a bit more info about that gluing fixture?

[@cjc4765]

Best vid yet. Amazing info! Kevin, you are to modest. You are not only a violin maker, you are the only living human who was certified by Jacques Francais! If anyone is reading this and doesn't know who Mr. Francais was, he would just glance at an instrument and just wave it along like rubbish if it didn't show any sign of greatness. Just a glance is all he needed! For him to actually look at an instrument ,handle and value it, it would have to be a Guarneri or Strad or Rocca, Bergonzi, Ruggieri (Or Kevin). He was the greatest appraiser that ever lived. He sold half of the Stradivari and Guarneri instruments in the WORLD during his lifetime. Kevin, I think Carlo Bergoni inherited Strads tools after his sons gave up the workshop. Do you have any knowledge of this?

[@kevinleeluthier]

Everything you say about Jacques Francais is true, and I miss him. Long story short: Yes. Bergonzi inherited/was loaned quite a few of Stradivari's tools. Later, Count Cuzio purchased all that remained (many of the wonderful ones had "disappeared") from Antonio's son, Paolo. After going through other owners, most of the molds and templates are now in the City of Cremona's museum.

Hi! This is a well done series! Is the 1694 manuscript where you saw the violin press the Diderot encyclopedia mentioned in the description, or is it another book?

[@windalkaid7088]

Love your videos always, really like your style!

[@charlesblithfield6182]

I felt like using sandpapers and even certain rasps at times is not traditional and therefore to be avoided, it certainly is more time consuming, but I realized how much exacting control they can give. Making art to me is a meditation as much as anything and “cutting corners” antithetical to why I am even doing it. I avoid power tools for this reason. I am no professional and appreciate your perspectives very much.

[@kevinleeluthier]

I have made many instruments without the use of any modern tools, yet after realizing that a sculptor's hands are best when fresh (one of the rare quotes of Stradivarius), and that Stradivarius had apprentices rough out most parts of his violins while Guarnerius had the assistance of both his father and wife, after double carpal tunnel surgeries, I decided to at least rough out some of the wood using a bandsaw, jointer, etc.. Please don't take offence, but the original masters did use sandpaper and rasps at times. It's amazing what technologies they had that have not been documented properly on the internet, or documented by others/historians who didn't do their homework. Never limit yourself by what others "think" the old masters did or didn't do. Stradivarius used his vast wealth to not only make things better, but also quicker and easier.

[@charlesblithfield6182]

​@@kevinleeluthier oh the tone of my comment didn’t communicate what I intended so certainly no offence taken. I have no problem with using power tools even myself I just wanted to understand the process by experiencing it using hand tools. I am new to this (violin making but I have made many things in wood) and noticed a kind of demarcation in videos and discussions about violin making concerning tools such as XACTO knives vs a fine Kiridashi. I love my curved Stanley 2 inch Surform and used it recently to shape some bike handlebars with a relatively complex shape I made with laminated maple veneers and thought it might make a good tool for helping the top and back of a violin versus or in addition to a finger plane with toothed blade, but have not seen that tool mentioned in researching luthiers tools. I am going to take the quicker and easier and Stadivarius advice seriously.

[@kevinleeluthier]

@@charlesblithfield6182 Sounds like we are more kindred spirits than one might initially think. = My advice about the Stanley Sureform is to use what works best for you and gives the best results with the most pleasure. :) As for me, I've been using Ibex toothed and plain curved sole planes (standard and modified shapes) for so long that they have become part of my hands.

[@charlesblithfield6182]

@@kevinleeluthier because this is not a profession I can take my sweet time. When making art the thing that mattered most was the process and I recall on some of my larger pieces working for 8-10 hours barely stopping, the time seemed to disappear. I make very technical art with many steps so making a violin seemed a natural fit plus at the end I get an instrument to play. I know the final result won’t be professional but I can try to achieve something that’s at least decent. Do you mind if I ask the very occasional question? I use the Johnson and Courtnall book and many videos and assembly sites but still find the odd thing not answered.

Have you heard of the old masters using horsetail plants as sandpaper??

[@kevinleeluthier]

Yes, first in the early 1990's at violin making school, and quite a few makers swear by it. Yet, even though it grows naturally in my valley below the violin shop, I have only used it on a couple of my instruments, because in my hands, steel wool with the proper backing seems to fit the bill for me. Yet, everyone's fingers and hands are different. Thanks for watching! :)

[@michaelwhisman]

Where can I buy one of those large holding devises??

[@marknichols7861]

I am curious if you know what the center hole purpose is in Stradivari's cradle that was used to hold the belly and back while he carved the wood. It seems to be an odd place for fixturing. My guess is that perhaps he glued the back and belly in place while carving and then used the holes to put a tool through to knock them out.

[@lustucrugf5591]

Hi, nice video. I'm pretty sure the convex arching on the back side of the ribs of the instrument is a result of deformation, isn't it ? endping and neck heel being pulled by the string tension, in many instances this effect is mirrored on the top side of the ribs, which end up being concave rather than flat.

[@kathleenkeane4364]

Always wanted to play violen. No money back then.but five years ago life improved and could afford one, how it has changed my life,I call it my life saviour,and it is, I think I'm a great player,but honestly not really.i play with a group once a week,and I call myself the last sub.i paid 500e for it,might get a better one soon,but I will keep my first love, I'm 78.

[@kevinleeluthier]

Wow! You are an inspiration to us all.

[@rody3199]

Great video as always, Kevin! I always learn something new every video. Also, quick question: Should I get a two-piece or one-piece back? Is it just for sound preference or is one objectively superior to the other? (I ask this because I plan on purchasing a violin from Fiddlershop called "Fiddlerman Master Violin Outfit". They offer both one and 2-piece backs. *costs 1000 dollars, dried 10 years. It seems like a good violin for a beginner like myself that doesn't break the bank!)

[@kevinleeluthier]

One piece backs traditionally cost more because they have to come from a larger tree, etc.. As far as sound, if cut on the slab, they tend to have a smoother deeper voice. If quarter-sawn, they tend to have the slightest bit more character, but ever so slightly tend not to be as balanced as a two piece back. Otherwise, it's simply a matter of taste. The proof is in the pudding, yet, at a glance, the Fiddlershop Master Violin Outfit looks very promising and they are showing a very nice looking one piece back for that price.

[@nestordiaz6848]

Incredible video, you are the best luthier on KZbin!....I have a professional Gliga violin, Stephen Weiss Violins, what do you think about it?

[@cmkaco]

This is fascinating. It appears that there is a concave curve in the C bouts, but then it looks like it gets flattened out when you sand the upper and lower bouts. Yet, when you are explaining the curvature, it looks like it is there. So, is there a concave curve at the C bouts and a convex curve at the upper and lower, or does the whole back end up being flat at the end? Thanks!

[@kevinleeluthier]

It's tough to get the camera angle to show everything correctly. The entire rib structure, including CC bouts is flat where it comes in contact with the belly, and convex where it comes in contact with the back (similar direction to the back of a double bass), with most of the curve being at the upper third. This really stands out when looking down the sides of original Nicolo Amati violins.

[@AnHebrewChild]

Merry Christmas-- Do you make any in the tradition of Stainer? Or would you say you specialize in violins for Classical-Romantic era play? I like Renaissance & Baroque, and even high baroque often feels too modern for my ears :D My apologies, btw, for what may easily have been perceived as negativity in another video's comment section. You seem like a really nice person, and certainly passionate about your craft. It's refreshing. I just have an allergy against "distressed" look -- whether Antonio and Giuseppe did this, doesn't change my opinion on it. To me, it'd be like a patron asking a bible-binder to make the pages & spine appear worn so as to give the fellow church goers an impression of greater piety. And distressed furniture & clothing... "purposeful patina," don't get me started... anyway, I'm curious your thoughts & experience in making for customers looking for early music instruments.

[@kevinleeluthier]

While I have not made any short, thick Baroque style necks, I do make whatever sound, response, and style that the customer desires including "immaculate." I have a particular love for the style of Jacob Stainer's instruments with "The voice of angels" as mentioned in the book "Clay Angel."

[@adifferentangle7064]

Who do you cite for your assertion that they used abrasive paper on a flat piece of glass or marble? Sources?

[@kevinleeluthier]

When it comes to the techniques of the masters, the most important references are the instruments and the tools of the masters themselves. When it comes to the "secrets," most have been handed down by others who visited their shops and the various masters at The Romantic School of Music.

No. There is one video that stands out above all others as the "most refined" of all. It was so refined that it was played on television about a hundred times: World's Dumbest Hillbillies 4 kzbin.info/www/bejne/pZyYoIushLCpmKM or kzbin.info/www/bejne/gGOXp2R-qaiKepo Go to 39:34 or 37:01 depending = I was the winner. Having a little "redneck" deep down inside can help make you a better fiddler and square dance caller, but don't tell anyone about this video because it could possibly hurt my reputation as a Master Luthier. :) And yet, I have sold some of my most valuable instruments to farmers and fiddlers. (One mortgaged the family farm in order to purchase it.) Also, in 1931 Henry Ford purchased "The Doyen," one of the finest Guarnerius del Jesu violins in existence to be used in his square dances at the factory.
