Watch as Curtin's Dominic Howman presents a lecture on how musical instruments produce sound.
Out of curiosity and the need to make improvements, scientific studies have sought to discover systematic ways of making desired changes to sound production. However, some types of musical instruments are much more difficult to understand than others. For example, the way violins work has been known for some time, but some of the basics of the acoustic guitar continue to remain as elusive as the fine subtleties of a Stradivarius.
This lecture was presented on 23 March 2011.

Even though Blackbird sounds more like road-kill, don't be put off by the initial demonstration. If you can get past the introduction, there is quite a lot of accurate, well-presented information here. I wager most of these negative comments were made after hearing only the first 2 minutes of this 1 hour presentation, so those interested in learning something should keep watching.

I couldn't agree more. However, I would be concerned about the building skills of a highly skilled player. Each vocation requires a lifetime of study and practice, so it follows that a master builder cannot and need not be a master guitarist. After all, I thought I knew a little about how guitars worked until I listened to the rest of this presentation, so in the reverse situation, I would have made a real fool of myself. Even so, he'd have done himself a favor to have someone else play the intro!

the average luthier probably starts off learning to play then discover they love building guitars a lot more and put their minds to that. Id bet most luthiers arent very good players. And very few great players could build a decent guitar

As others have pointed-out, the guitar playing at the beginning is excruciating - is the guitar even in tune? However, apart from that, it is an excellent and very informative video. Dominic is clearly a real enthusiast and really seems to know his stuff. He also puts it across well in a clear no-nonsense way. There's a lot of hype out there about guitar 'tone', but this video helps debunk or explain a lot of the myths. Thanks for posting - keep up the good work :-)

This guy was really informative and got a lot of flak for his playing and tuning . These instruments probably came directly from the atmosphere of his home; through all kinds of weather to the classroom. He explained that tuning would be off , but few of the critics here seemed to listen. As for his playing; he is a physics teacher/hobby builder. If Tommy Emanuel was playing -- the instrument would have been better displayed ; however this was not so much a performance but a physics class . Most critics here fail to realize this either . I did get a chuckle when he played the intro to Smoke on the Water on that old Aoud ( hope the spelling was right). Showing a 12th century Arabic rock group coming up with this would be a good sketch for SNL .

The 'sound hole' is actually an air hole, used to prevent any standing waves that would be self-interfering by letting air escape. People that record guitars for a living know this, and do not mic the guitar at the hole, but some where else. Almost all of the sound is produced by the vibrating top, so the materials and construction of the top is essential for a specific or pleasing sound. Thanks for the video; I liked it.

i have ten guitars at the moment and i've owned about thirty in the last few years, my pride and joy being a '66 gibson J45, what you said about vibration going through the back to the player, and sound holes that are cut into the sides makes sense, i also have a martin OOOX1, spruce top but HPL back and sides, basically laminate, i think it's the best guitar i've ever touched, the sound is clean, the bass growls and the trebles ring, but what makes it a complete experience is that the back passes the vibration to the player, so you get to feel the guitar as well as hear it (i play fingerstyle pretty exclusively). i've been looking at (not playing) composite and carbon fiber guitars and i think the same might be true of them, mcpherson and composite acoustics guitars sound a whole lot better than some solid wood.

As an engineer and a solid body hobby builder, I found this exactly the kind of information I wanted. The whys of instrument making have always fascinated me. Obviously the epitome of guitar building is the acoustic. Never tried one because of the precision required and the tools needed to get it right. Yet I now have a better understanding of the physics of the build. This is something that takes extreme patience, like learning to play, which is why I'm not much of a player. Would be nice to see a follow-on for the solid body and ways to optimize it and the various sounds you get from different woods. Thanks and remember Leo Fender was an engineer and allegedly didn't play guitar.

Thanks very much, Dominic, for sharing your extensive knowledge. Very helpful for me, thinking about my next build. I have a question about vibrations of the table: I got the impression that the monopole mode pumps air in and out of the sound hole, whereas the cross- and long dipoles merely move it within the guitar body (because one side of the soundboard goes up while the other goes down, suggesting cancellation). So, as I understand, the dipoles only make sound from the soundboard, not through the soundhole and, even that from the board would cancel to some extent for the listener in front. Leaves me wondering why the fanstrutting of classic guitars is designed to increase the cross-diapole (as I understood you to say). Surely it wastes sound energy and makes them quieter? Big problem in a concert hall.

19:49 He clearly mixed up between Venetian and Florentine cutaway... The Venetian is actually easier to make these days because machines can bend the sides through the use of a mould. Florentine requires a bit more handy work as the sharp curve is joined by two pieces of timber and a triangular supporting block at the location of the cutaway to help stabilising the cut it requires longer sides material to join otherwise you end up with weird grain pattern. That's why only high end custom built acoustic guitars have Florentine Cutaways as a standard e.g. Ervin Somogyi, Michael Greenfield, Matt McPherson...etc

@curtinuniversity
@curtinuniversity 7 жыл бұрын
Hi mailvilla, I think the dark piece of wood near the soundhole you refer to is the bridge plate. It is made from hardwood and has a couple of purposes. Firstly it is the piece of wood inside the guitar that the ball ends of the strings sit against. Even though it is hardwood, it can show a lot of wear from the strings on very old guitars and needs to be replaced. Its second function has to do with controlling the bridge rotation. The bridge and bridge plate form one of the most important braces on the guitar top. You can actually measure how much the bridge rotates before it is strung up and after it is strung to pitch. Attaching something as simple as a skewer stick to the bridge so that the stick protrudes towards the neck of the guitar and parallel to the top will achieve this. A large thick bridge plate will inhibit the bridge rotation whereas a smaller thinner bridge plate will allow more rotation. This is simplified as the bridge plate also contacts the X braces which act as a system. This is not a trivial subject. My style of building places great importance on how much bridge rotation occurs - as that is the sum of soundboard stiffness, brace stiffness and placement of braces. - Dominic

Wonderful video thanks for sharing. I have a question if you would be so kind. Can you do a video on voicing the sound board and share your techniques? I noted the tapping and the music box. I use a tuning fork to get an idea but only have one fork in "A". From a physics perspective would you recommend all 8 notes to get a feel for resonance or is that a little over the top? I have only built a few guitars and I am now exploring voicing from a scientific perspective and would love your input. Also have you given any thought to chambering the body or know of anyone who has? What I am thinking is Dr. Bose's approach to speakers. But anyway this was really really thoughtful and provocative talk on the subject thank you from the bottom of my heart.

He doesnt get into the soundhole design or positioning. What if you make it square? What about ovals and slanting them with regard to the centerline? What about F holes versus the sound hole? What happens if you remove it altogether and just use f holes or more randomized holes radiating from the bridge placement? What about drilling out the fibbonaci sequence in terms of holes from the location of the centerline on the saddle? Has anyone tried that!? It seems pivotal to its breathing and resonances?

The info is extremely good for luthiers :) The reason the intro sounds so bad is is because it's only partly picked up by his lapel mic. If he was playing into a proper mic, it would have been more even. As far as tuning, that could be an artifact of video speed, etc. Way to many influences to cancel out in an inexpensively made video in a glossy classroom setting. Do it all over in a sound studio correctly mic'd, and most folks would not have the gripes ...

Most people take PLAYING music far to seriously. The forget its PLAYING egos destroy fun and the ability to learn and grow. Ive been around far to many of those. I would join you guys for beers but NO playing or fun conversation this is music and building instruments.

Fair enough, the playing at the beginning is a shocker but the rest of the video is really interesting if you want to know about the internal construction of an acoustic and why it's made like it's made. A really good place to stat if you are thinking about making one yourself.

What do you have to say about the old ladder braced system?

Hi +Ellen Mach, I have no experience building ladder braced guitars. Greg Smallman has used this design successfully for his classical guitars. The premise is that you can get a very stiff top with ladder braces, and so you can make the top much lighter. I don’t know anything beyond that. - Dominic

FYI at around 20:00 when you are holding your guitar and talking about the cutaways you have it backwards. the one you are holding is a florentine cutaway and the smooth curved style is a venetian cutaway.

I enjoyed your video. It was well presented. I have a few questions: Does the species of wood (sitka spruce, western red cedar, red spruce, etc.), used for the bracing on the soundboard, have an effect on the sound of the guitar? What species of wood do you prefer, for the soundboard bracing, and why? Does the style of kerfing (traditional kerfing vs. reverse kerfing) have an effect on the tone of the guitar? Can you provide more information on the vibration tool used to "break in" a new guitar? Thanks in advance.

Hi +Chad Redding, the species of wood used to brace the soundboard (and back) of a guitar is not as relevant as the stiffness of the wood used. Wood has such great variations in its mechanical properties that it is possible to make braces from two different species of wood that have identical mechanical properties. On the other hand it is possible to use the same species of wood from two different trees to make a brace and they have wildly different mechanical properties. So it is wrong to think “Martin used red spruce for their pre-war guitars so I must use red spruce to get a good sound from my guitar”. I use Sitka spruce for my bracing only because it is readily available to me. I weed out any brace stock with runout and skewed grain. What I do, and anyone serious about making guitars should do, is to consider the stiffness of the brace stock. There are many ways to measure stiffness. I prefer the old fashioned one of checking the grain count and flexing the brace with my hands. I don’t build with any pre-determined stiffness for individual braces, but find the stiffest wood and use that for the main X braces and the transverse braces on the lower bout. The skill in guitar making is not in what species of wood you use for bracing but how you carve the braces to control their stiffness. Using the stiffest wood allows you to make a brace with less mass. I haven’t explored the effect of different styles of kerfing - I use a traditional style. I have found that basswood is an excellent material to use. I was told by Bob Hoover during a tour of his Santa Cruz workshop that he liked the way basswood decouples vibrations from the top to the sides and the back to the sides. I was lucky enough to play some Santa Cruz guitars after the tour and have been a believer ever since. I handcut all my kerfing and have to say it’s my least favourite part of guitar making by a long shot. The best tool for breaking in a new guitar is your hands. I do have a Tonerite which is really just an expensive fish tank pump. Does it work? Yes it does take a brand new guitar and “settles” it down or “breaks it in”. It won’t change the fundamental tone of a guitar. Only someone who has strung up a guitar for the first time understands how much the sound changes in the first few weeks of stringing it up. Initially you might love the sound of a newly birthed guitar. Later that night you play it and it sounds awful. The next day it sounds heavenly etc. Once the tension soaks into the wood and it has been played (or Tonerited) for a few weeks, it’s essentially broken in. I sometimes get to play a friends guitar that gigs 3 or 4 nights a week, 3 hours at a time. That guitar sounds so wonderful and deep because the wood constantly gets a real workout. I think perhaps that is more what a Tonerite was designed to achieve. - Dominic

It's actually very common for instrument builders (Luthiers) to not be very good at actually playing the instruments. I was surprised when I first learned this but this was how it was explained to me. In any given month they could build a guitar a violin a ukulele and a banjo. All these instruments are pretty different, and it's hard to build any real proficiency when you're learning them all at the same time. It's much more efficient to master 1 or 2 of them, then learn how to translate the skills.

Mastery takes time only so many hrs they play more instruments instead of focusing on just playing one. Most guitarist cant build one, it may look right nut would sound shitty.

I don't see how lining material could decouple the top from the sides. If their mass and cross section are the same the difference should be minimal.

great video! One of the key take aways was the physical properties of the soundboard playing a role. A particular species may be known for its qualities but those properties can be found in woods not necessarily known to be reputable. so the take away was, go with the properties of the piece you have. That being said, how could one do a quick specific gravity or modulus of elasticity calculation when you have a wood selection in front of you?
What no one will tell you about acoustic guitar soundboards!
