I have been researching guqin recently, the photos of qin construction were well done… how did you design the template overlay for the cuts, also … for the routering ? I would like to make my own qin (although I am thinking of using nylon strings
Thanks for the comments.
I read the instructions from Yuguzhai Qinpu (Abiding with Antiquity). There’s an English translation by Jim Binkley who lives in Portland, OR. Basically, the instructions are in words (draw a straight line, mark off 12 divisions, inscribe a curve, etc.) I translated that into math and just plotted it. But, I deviated a little but and tweaked the formula to get a wider instrument so I can play with the profile. Then I drew lines on the boards and routed away. I think I was too detailed, and if I do this again, I would make less contour lines. It was too tedious. Do you play, and where are you located?
Thanks for such a fast response… I have just started reading the book Yuguzhai Qinpu (Abiding with Antiquity) now… 🙂 I am at the very beginning in this pursuit … but I have heard that a long journey begins with but one step… 🙂 I will try to duplicate your method of translating into math formula… do you mind if I consult with you if I run into problems?
That should be fine. Let me know whenever.
By the way, which city/state/country are you in?
(I’m working on restructuring my blog, so links might change. You should be able to re-navigate back through my homepage.)
What software did you use to plot the template? Also… which do you think is better, the silk string or the nylon/metal string…
appreciate it… currently in Dallas area, Texas
My name is zhangwenlong. I come from The Second Hospital of TangShan.I am a hand surgery doctor and want to touch with you.
It’s ZhengXuGuang who tell me your website.
My QQ number is 120467060.
Hope your reply.
Good to hear from you. I don’t have QQ. Email is best. Feel free to write me. email@example.com. Please send my regards to all my friends: Dr. Zhang, Dr. Zheng, Dr. Wang, Zhang JunJun.
Calculated contour lines and just plotted them x-y. Any simple program will work. Silk is very painful to deal with. The sound is rough. It goes out of tune constantly. Do you play?
thanks for the tip about silk strings… it saddens me to hear it though… I listened to “Wild Geese Descend On a Sandbank” played using silk string, and again using metal/nylon string… while not as loud, there was distinctive overtones… the research I did said the silk string last about 7 years… good sound between years 2-5… normally breaks at the point of contact at the bridge… extend life through splicing in more silk string at the point of breakage…
I am literally just beginning… doing my background research first… studying the structure of the instrument…
Hi Danny, as I slowly inch forward in my understanding of matters related to guqin… I noticed you are using a transduction pickup… why did you go that route? I have another question… did you vary the depth of the wood to accommodate the thickness of the string above it… thicker under the lower tone… thinner under the higher tone? I read this technique is used to facilitate the transmission of the formant frequencies into the sound chamber…
I happened to have that pickup from another instrument, so I just transferred it over. No other reason in particular.
About the thickness: guitars have struts, and violins have the bass bar. In the guqin, because the design already calls for wood to be left thicker across from the soundholes, I didn’t vary the thickness.
Oh my goodness, it looks so real, saturated with blood! Believe it must be fresh harvest, straight from OR with the operating room basin at the bottom. Well done, Danny. I vote this is the best dish for the Halloween. Believe that the ancient kings would love this dip better than the real monkey’s brain that they had!!
Thanks so much. Had such a good time making it.
Nice idea! Looks great and I am sure tasted the same…
So glad I’m vegetarian.
Danny, Beautiful loaf of artisinal bread. You are truly a polymath. Talents in all areas. There is magic in a great loaf of bread, some say religion is found in proper bread. Thanks for sharing.
Thanks, Monte. I love this basic bread recipe. It’s so simple yet wonderful. Chris Jobe shared the original recipe with me, and I think the olives add another dimension of complexity—a great loaf, especially with some assorted cheeses.
a good time
Your blog and photos are beautiful! The photo you took of the mountains from our condo is stunning! We are happy we could play a small part in your amazing family trip to the Canadian Rockies. Please come back and visit us again!

Hi Danny, I’m in Kunming now getting ready to begin building my guqin.
My son gave me an older version of Mathcad his teacher had around so i will that for the calculations. I’ve been learning to play the guqin in Kunming 🙂
I changed out the strings on my qin… the silk strings are much easier on my fingers and I like the sound more than the steel strings…. i coated the strings with candle wax and rubbed the wax into the string using a cotton cloth before using them… the first two weeks I had to adjust the strings constantly as they stretched out… however, after two weeks they settled in… several months now… they don’t change at all…
what kind of wood did you use for the bridge?
Hardwood, like jujube or rosewood. I just met with Jim Binkley and had a nice talk. He and several other makers and I agree that the author of Yuguzhai probably never made a guqin.
Dear Danny, I am looking to build my first Guqin and need help on the dimensions. Any information would be willing to give would be greatly appreciated.
All the best, Scott
Good to hear from you. I mapped out the dimensions from Yuguzhai Qinpu, and then tweaked it. I recently started taking lessons, and my teacher said the top needs to be a little more rounded, so you might want to modify. Also, I had the chance to finally meet Jim Binkley, who translated the original construction text. His impression was exactly the same as mine–that the author of the Yuguzhai probably never made a guqin before. Following the directions precisely (what I did the first time) ended up yielding an instrument that doesn’t play well. Feel free to e-mail me: firstname.lastname@example.org. Where are you located, and what inspired you?
That’s a lot of pieces to be taught within one lesson. To top that off, new pieces every time? I’m surprised that you can remember them all within such a short time! Props to you, Dr. Wong, for your impressive memory.
And oh, don’t forget to enjoy the music and chew slowly. 🙂
Taking lessons has been a lot of fun and very rewarding. I started at the end of April, and progress has been good. So far, I’ve learned nine pieces, in order: 仙翁操, 湘江怨, 古琴吟, 秋風詞, 歸去來辭, 良宵引, 酒狂, 極樂吟, 陽關三疊. I’ve enjoyed every bit of it. I don’t try to rush my teacher in my twice-monthly lessons; he just gives me pieces as he sees fit. Looking forward to my next lesson this upcoming Sunday, July 15. (By the way, I had enjoyed looking through Toronto Guqin Society’s website and your bio. I self-taught as well, years ago, and it’s nice to finally take real lessons.)
Hi Danny, I hope to start construct my Guqin within two months… I have been gathering supplies and tools… I just finished playing 阳关三叠… I would appreciate your feedback on my playing… It is only 1.6 meg… Can I send it to you?
Sure. Just e-mail me. Are you in Kunming or in TX?
I’m trying out your recipe tnight. Don’t have marinade, will see how it turn out. Thanks for sharing.
My name is Richard Houghten. I am a musician and composer. I really want to ask Lui PuiYuen a question and have no idea how to get a hold of him. Any info would be be so much appreciated! That’s really cool that you have started taking lessons. I too am really interested in starting. Thanks so much
I can probably ask him for you. My lesson is this Sunday. You can try calling him too… do you speak Chinese? And are you still in Seattle?
Now that Fall and cooler temps are approaching, it is a good time to plant brassicas (Cruciferae). I am hoping to have some seedlings for you at my upcoming appointment (broken wrist, no cast due to CRPS). They are rare forms from Italy. I also have many succulents you are welcome to dig up for your garden, etc. And the huge pot of vetiver….
I enjoy visiting your website from time to time. I am delighted my adopted town has a polymath of such amazing abilities! I do hope we can exchange garden visits at some point.
Marjory Harris (Cielo Lane)
Thanks, Marjory. I don’t consider myself a polymath…but, I do enjoy growing interesting vegetables. Brassicas sound wonderful. I just harvested my last cabbage and cauliflower. A garden exchange visit would be good, maybe in the fall after I get some things in order.
Hi Dr. Wongworawat:
What was the inspiration/impetus for using fiberglass mesh as a soundboard protectant instead of the more traditional mud? I find that aspect of your work along with the meticulous attention to detail intriguing.
The traditional material was not mud, but rather, the sap from the lacquer tree, which is related to the cashew and poison ivy. The compound, urushiol, undergoes oxidative polymerization to form a plastic-like material (you can look up the compound urushiol online). Then, to give it more durability, the ancients used deer horn powder and other additives, like rust water and bile juice. I am by no means a purist. If the ancients were here today, they would probably look for a modern equivalent for the urushiol. I chose epoxy polymer. And instead of going out and finding deer horn and rust water, I chose marine fiberglass. It virtually disappears under epoxy and has worked very well.
hi, my wife really like photos that you took for us , and wonder if you could send the original pics to us (using files share website like Dropbox or other).
I want know which software you build your website, wordpress? could you give the RSS link, so I can read your articles in Google Reader?
I came across your video while searching for information about Guqin. I am also learning Guqin and had my fourth lesson last week. I hope I can play as well as you by my tenth lesson. I plan one day make my own Guqin as well.
Your guqin skills are awesome! How long did it take you to learn and how long have you been playing? I am also interested in starting.
Thanks, Frank. I started taking lessons several months ago–April 22. So, it was 4 1/2 months when I recorded this piece. Basically, I’m still a beginner.
You play real well and I guessed you are not Chinese educated. May I have the contact details of your teacher, so that I can also learn of him? I only play the guzheng, and I have been wanting to learn the guqing.
