Urban Luthier Report post Posted June 28, 2018 One of the projects I've had in the back of my mind for years is to build a cello for personal use. I have collected a number of plans over the years from the Strad (Strad De Munck and Davidov, P.G. Rogeri, Goffriller, Small 5-string Amati). I'm interested in hearing from members who have built successful baroque cellos. I'm looking for a plan that would be most suitable for basso continuo (Think Bach Cantatas) Guidance on baroque setup considerations in a modern world - lower bridge height, & neck angle? (look at the video below at about 2:50 -- the bridge may be a wee bit lower, but the setup 'geometry' looks modern to me) I'm leaning towards the Strad B form or the P.G. Rogeri. The latter however is a good 2 cm wider in the C-bout than the Strad. wondering if there is any concern with bow clearance on this model. Quote Share this post Link to post Share on other sites
JacksonMaberry Report post Posted June 28, 2018 I'd be inclined towards the Amati, and you could leave the high e off if you wanted, but it could be fun for exploring some of the solo rep too. Quote Share this post Link to post Share on other sites
Mark Caudle Report post Posted June 28, 2018 There shouldn't be a problem of bow clearance if you keep the bridge curvature a bit less than modern. Quote Share this post Link to post Share on other sites
Barnes Ziegler Report post Posted June 28, 2018 I personally would recommend to make a strad-model. You can get a lot of infos from Stradposters and so on, but the biggest advantage, especially if you want to build a baroque instrument, is that you can get pictures of the original stradivari templates wich are published in the catalog of the Museo del Violino in Cremona. You still need to interpret them of course but you can get the general idea of how he wanted the instrument to be. Also I would recommend the articles by Roger Hargrave on baroque-set up. He suggests that the geometry of the set-up wasn't that different to the modern one. Also Pollens writes about that topic in his book about Stradivari. And there are some measurements for the bass bars too. Good Luck with the build! Quote Share this post Link to post Share on other sites
Urban Luthier Report post Posted June 28, 2018 Thanks good advice! - I have Pollens and check the neck angle on the cello templates which is about 85 degrees - not all that far off modern. I'm quite familiar with Roger's thoughts on Baroque setup. I'm curious about the feedback of those who have built baroque cellos for clients and thier point of view on setup.

PhilipKT Report post Posted June 28, 2018 Regarding the commentary in the video, I was quite surprised to be completely engrossed by a doctoral thesis on the history of the endpin, Which dispel the myth that the endpin was not invented until the 19th century. On the contrary, it was available and in use long previous, although the use was not universal. So the charming cellist in the video is mistaken. For those who have interest, I would highly recommend you google that article, which is quite fascinating despite the subject. Quote Share this post Link to post Share on other sites
Mark Caudle Report post Posted June 29, 2018 I would continue to question the findings of the "authorities" about set up. I have seen quite a few original cello necks from the mid 18th century and earlier albeit mostly mangled and reset. One constant feature on all of them is that the notch that fits around the top of the front plate is only sufficiently deep to allow the fingerboard wedge to clear the plate. ie no significant overstand. This is in contradiction to Pollen's assertion that the overstand should be about 6mm according to the ||Strad templates. Around 1750 or '60 I have seen original neck English cellos that do have overstand (Thomas Smith for example) and I suspect that this started with the greater use of thumb position as it is awkward to avoid a hollow wrist in thumb position if the fingerboard is too near to the front plate. My feeling is that norms were also for shorter necks and smaller bass bars and soundposts although exceptions to this are widely quoted. Also the Strad cello bridge templates are much lower than modern. I think Pollens does tend to favour sources that support his theories although as a non-academic I am not in a good position to challenge them. Another theory that I am not convinced by is that because string tension was heavier than modern in the baroque period, instruments were necessarily thicker plated and have been subsequently thinned. Again this has certainly happened but is not proven as a rule. The idea that most instruments were built to survive into posterity is strange. I am sure that the majority were made to serve the contemporary music and musicians. I particularly remember a conversation with Dietrich Kessler who had the opinion that French baroque viols were built with very high bridges that caused such high pressure on the front plates that they would collapse after about 15-20 years. But during this time they were wonderful musical instruments. I have tried quite a few copies of B form baroque cellos and do not feel that they are always the best model for this purpose. I'd try something a bit smaller but with higher arching. Quote Share this post Link to post Share on other sites
Urban Luthier Report post Posted June 29, 2018 Thanks for your insights Mark! Regarding the model you mention something smaller with higher arching... I have a plan for the P.G. Rogeri cello I mention above - it has a belly arching hight of 28.5mm and it is about 20 mm shorter than the strad Quote Share this post Link to post Share on other sites
Mark Caudle Report post Posted June 29, 2018 I have actually made a baroque cello on the PG Rogeri model and it is a good model and turned out quite well although has a bit of a wolf problem. But I play and have played a lot of smaller instruments and they lack nothing in power and bass fullness of tone. For example I have a 702mm N. Chappuy which is a bit late for baroque but has a good strong bass. If I was using Strad plans I'd go for the De Munck or even a Guadagnini although again that is a bit late for Bach!

Urban Luthier Report post Posted July 11, 2018 by the way here is a video of Enrico Dindo playing the P.G. Rogeri mentioned above. Quote Share this post Link to post Share on other sites
Urban Luthier Report post Posted August 1, 2018 Any one have any experience with the late strad cellos built on the small form? I just found the 'Saveuse’ cello 1726 poster in my collection. Rather small at 724mm. you can see it here https://vimeo.com/212577059 and here it in this clip Quote Share this post Link to post Share on other sites
Urban Luthier Report post Posted August 30, 2018 Still researching... Any thoughts on this lovely Rugeri cello in the Royal academy of music? I saw this when I was in London a few months ago. Looks and sounds really nice. Seems it was cut down at some point. I overlaid the Rugeri outline with the 1717 P.G. Rogeri (see ref to strad poster above). Apart from the rather flat upper bouts of the Rogeri, the outlines are virtually identical. Quote Share this post Link to post Share on other sites

Love the tone (timber?) that I've begun to identify with the wider celli. I've settled on the 1717 P.G. Rogeri for the model I plan on making. I don't really care for the flat outline by the neck block and had planned to round it off similar to the F. Rugeri in the link. I will start sometime next year. Have you made progress on your Baroque cello project yet? What model did you select, or who are your top contenders if you haven't started? -Jim Quote Share this post Link to post Share on other sites
Urban Luthier Report post Posted September 2, 2019 HI Jim I have made some progress. I was all set to go for the P.G. Rogeri cello based on the poster published by the Strad. I even drew the outline up in CAD (I did increase the length by 5 mm at the top to give it a slightly rounder (and increase the stop length to something more modern). See below. I have the Rogeri template in PDF - just PM me if you want it I did a 180 at the last minute and decided to go with something more conventional - a Strad B from based off the Gore Booth and Davidov. I haven't made a cello before and there are a ton of strad related resources available to help along the way. I drew this one up by hand. Below is the 'work in progress' form I made for the strad b - double thickness baltic birch ply. A ginormous pain in the you know what to make. Quote Share this post Link to post Share on other sites
Jim Bress Report post Posted September 2, 2019 The mould looks nice. I understand flip flopping on plans. I've been planning on a Joseph filius Andrea Guarneri cello (1710) based on a poster from Cremonabooks, however nothing is to scale and no archings. Not insurmountable, but the Rogeri is very similar with much more information in the poster. My attempt may be somewhat of a hybrid between the two aesthetically. How thick is your form?

Urban Luthier Report post Posted September 3, 2019 form is ~35 mm (two pieces of baltic birch laminated together) Give how difficult it was to work with this material (at this thickness) I'd use just regular plywood next time. Quote Share this post Link to post Share on other sites
