Best Little Guitar Festival in Texas

Aaron in the Booth at the Brownsville Guitar Ensemble Festival 2012

Aaron and I just got back from a trip to the University of Texas at Brownsville.  We were there as a vendor at the Brownsville Guitar Ensemble Festival and Competition showing five of Aaron’s classical guitars.  Aaron is a luthier who builds hand crafted guitars for his company Wood Ring Guitars.

This is not the only guitar festival we have been to this year.  There are several classical guitar festivals that occur around Texas every year.  Many are centered around university guitar programs.  Many of the major universities in Texas and several community colleges and high schools and even some elementary schools now have classical guitar programs who are taught by a group of very talented guitarists.  This is resulting in more and more people being introduced to the classical guitar and the amazing music written for it.  The quality of the competition and the performances at all of these festivals is outstanding and every year the crowds get larger and larger in response to this.

I think of all the festivals I have been to in the past couple of years, I enjoyed the Brownsville festival the most.  This is not because the entertainment and quality of competition was not as good at the other festivals.  I favor the UTB festival because it is unique in that the competition is ensemble based rather than being individually based.  There is an amazing spirit that permeates this competition because the ensemble competition requires each group of individuals to focus on working together as a team rather than competing as individuals.  Dr. Michael Quantz is the head of the guitar program at UTB and he has created an elite classical guitar program that is affecting the classical guitar scent throughout Texas and the Southwest in an extremely positive way.  I think many of the other university guitar program heads in the Southwest would agree with this, based on their growing participation at the yearly festival.

There is a 75 MPH speed limit between San Antonio and Corpus Christi.

The 75 MPH speed limit is nice when driving long stretches through Texas.

I have included quite a few photos from our trip from Wood Ring Guitar headquarters in Weatherford, Texas to UTB.  Aaron and I made the trip in one day, alternating in the driver’s seat every couple of hours.  This made it an easy drive.  We stayed at the Marriott Courtyard hotel which was recommended by the festival and we got a festival discount resulting in a nightly cost of $89.00 which was extremely reasonable for such a nice hotel.

Once we settled in at the hotel and got all of our luggage and guitars squared away, we relaxed a bit and then we went to a local Japanese restaurant for dinner.  The sushi was fantastic, but we learned to never order Thai food at a Japenese restaurant.  We ordered Pad Thai, which is normally a very delicious Thai noodle dish.  Instead it tasted like an odd mixture of Thai Spiced noodles in a spaghetti sauce laced with mexican spices.  Not very good!  We also dodged a bullet that evening when we ordered sushi because we heard later that the spicy tuna roll at various sushi restaurants in the area caused a rash of food poisonings.

This is the entrance to the concert hall.

The next day, we set up our booth at the new Arts Center at the university.  It is a beautiful building that has a gorgeous foyer and a wonderful concert hall that was acoustically tuned to perfection.   Our booth was in the foyer in front of the concert hall entrance.  Dr. Quantz and his staff met us as we entered the building to set up our booth and throughout the festival they were exceedingly helpful and made our gig at this festival extremely enjoyable.

For the next three days, Aaron and I talked to more than a couple of hundred people interested in touching, holding, playing and talking about the Wood Ring Guitars that we brought.  It was a great experience for both of us.  We met and talked to many folks who, like us, love the guitar and all kinds of guitar music, especially classical guitar music.  We also were able to visit with many of our friends who teach guitar and who play professionally.  We also had the treat of being able to visit with members of two groups who headlined the entertainment for the last two nights of the festival.

On Friday night the Texas Guitar Quartet played.  It was an outstanding performance from four of the best professional classical guitarists on the Texas scene these days.  This performance was done in conjunction with the realease of their first CD which is named Red for the title song on the CD.  The entire concert was played beautifully.  On Saturday night members of the Los Angeles Guitar Quartet played an amazing concert.  I have seen these guys play several times in the past couple of years and they always amaze me with their virtuoso performances.  This concert was no exception.  It included a premier of a new piece written for a large guitar ensemble written by Shingo Fuji in honor of the victims of the 2011 Japan earthquake.  Mr. Fuji conducted the ensemble which included both LAGQ and the UTB Guitar Ensembles.  It was beautiful and moving to be sure.  The entire program was extremely entertaining and the guitar playing was impeccable.

We had the beach almost to ourselves.

We had the beach almost to ourselves. This is me walking along the shore.

It was not all work.  We work very hard at this.  Sometimes we end up working seven days a week.  Thus when we get an opportunity to travel for business purposes, I am a big believer in having a little enjoyment and down time during each trip to experience the culture of each place we visit.  We did not have much time, so for this trip, Aaron and I drove to South Padre Island to have breakfast on Pier 19 and then to walk on the beach to enjoy the sun and the smell of the ocean breezes for an hour or so.  It was great.


Brownsville area border patrol station.

Lots of cameras must have taken our picture as we proceeded toward the border patrol station.

After the festival, we drove back home.  About 30 miles North of Brownsville we were stopped at a Border Patrol checkpoint.  We were asked if we were citizens and then told we could go on, but not before about 30 or 40 cameras had taken our pictures to help them determine that we were ok.




Bluebonnets and Prickly Pear Cactus just south of Marble Falls.

The Blubonnets are absolutely beautiful along the Texas rural roads this year.

As we proceeded north of San Antonio we were able to photograph some of the millions of bluebonnets that are currently blooming.  This year they are exceptionally beautiful because there has been abundant rain.  It seems to me the beauty and abundance is enhanced because of the terrible draught that we had in Texas last year.  The contrast from last year was amazing.



Aaron and I had a great time.  It is really cool to be able make a living doing what you love to do.  Aaron has discovered that he has a real talent in designing and making these guitars.  I have a strong science background and I have helped him, by using the principles of physics and acoustics, to work out a guitar design that really sounds great.  Combined with Aaron’s amazing craftsmanship and his unique artistic and design skills, I believe we are beginning on a journey that is full of adventure and fun all the while offering some of the guitarists of the world with outstanding instruments to play.  What could be better than that?


Auld Lang Syne – For Old Times


“Should old acquaintance be forgot and never brought to mind?” I think not. For everyone I have known, loved and lost there was something of them that I shall always keep close to my heart. 

It’s Later Than You Think!

I saw a Facebook entry one of my relatives posted this week that got me to thinking about all of the people I have known who are no longer alive, but still live quite vibrantly in my memories. The post was a quote my father-in-law, Dock Ringo, told his daughter on many occasions, “It’s later than you think.” The quote is from a song recorded by Guy Lombardo in November of 1949, entitled “Enjoy Yourself (It’s Later Than You Think)”. Now that I think about my father-in-law’s profession and strong association with music, it makes sense he would make that quote. He was in the juke box business. He owned many of them and as a result was aware of every popular song on the charts for many decades. This one in particular strikes a chord for those of us who are still alive, working hard to make ends meet and think we still have time to put off those simple pleasures for later when we will have more time and money, or so we think. 

The song lyrics go as follows:

You work and work for years and years, you’re always on the go
You never take a minute off, too busy makin’ dough
Someday, you say, you’ll have your fun, when you’re a millionaire
Imagine all the fun you’ll have in your old rockin’ chair

Enjoy yourself, it’s later than you think
Enjoy yourself, while you’re still in the pink
The years go by, as quickly as a wink
Enjoy yourself, enjoy yourself, it’s later than you think

You’re gonna take that ocean trip, no matter, come what may
You’ve got your reservations made, but you just can’t get away
Next year for sure, you’ll see the world, you’ll really get around
But how far can you travel when you’re six feet underground?

Your heart of hearts, your dream of dreams, your ravishing brunette
She’s left you and she’s now become somebody else’s pet
Lay down that gun, don’t try, my friend, to reach the great beyond
You’ll have more fun by reaching for a redhead or a blonde

Enjoy yourself, it’s later than you think
Enjoy yourself, while you’re still in the pink
The years go by, as quickly as a wink
Enjoy yourself, enjoy yourself, it’s later than you think

My father-in-law lived his life having fun making his fortune. He took the time off to spend time with us, taking us on numerous vacations and celebrating holidays with us as well. He had many traits I admired, his strength and strong will I appreciated the most.

To other old acquaintances I will not forget: 

To my grandfather George De Ridder, I owe my love of art for it was him who taught me to let go of my inhibitions and not be afraid to draw. 

To my father Marinus, who taught me to be strong and instilled in me an appreciation of science, literature and mathematics. He guarded his feelings and emotions, but inside was a very tender man who dearly loved his dogs, cats and my mother. 

To Mammy, my husband’s grandmother, who was remarkably outspoken and definitely not afraid to speak her mind or walk to the beat of her own drummer, I learned was it truly means to be bold. 

To my mother-in-law Eleanor, who wore her heart out in the open revealing her real emotions for everyone to see. She was one of the kindest souls I have ever known, for even though her temper was legendary her forgiveness was complete and infinite. 

To my sister-in-law Liz, who had such a dry sense of humor that I can not begin to describe how great it was. She helped me see humor in the unexpected. 

To Louis Duca, who worked with me at Glitsch Inc. and who taught me the fine art of selling fractionation equipment with a smile and sense of humor. 

To Bill Young, who taught both me and Danny to love the finer things in life (like single malt scotch). Such a presence he had indeed. 

To Cathy Streetman, my best friend and sister in heart. Her friendship and acceptance was so enormous, it was only matched by her generosity and teasing sense of humor. 

A Final Salute

All of these friends, relatives and business associates are gone in the physical sense but have left indelible marks in both heart and memory. I can’t think of a finer tribute to them than to acknowledge their contributions to my own life and how their existence influenced me for the positive. I can only hope that someday someone will feel the same about me.  For those of you who have also lost past acquaintances, friends or family, but kept a part of them in your heart, I dedicate this post to you.  At last, I finally understand the lyrics of Auld Lang Syne.  Read them below and perhaps you too will see what I see in them.

Should old acquaintance be forgot,
and never brought to mind ?
Should old acquaintance be forgot,
and old lang syne ?


For auld lang syne, my dear,
for auld lang syne,
we’ll take a cup of kindness yet,
for auld lang syne.

 And surely you buy your pint cup !
and surely I buy mine !
And we’ll take a cup of kindness yet,
for auld lang syne.


 We two have run about the slopes,
and picked the daisies fine ;
But we’ve wandered many a weary foot,
since auld lang syne.


 We two have paddled in the stream,
from morning sun till dine ;
But seas between us broad have roared
auld lang syne.


 And there’ a hand my trusty friend !
And give us a hand o’ thine !

And we’ll take a right good-will draught,
for auld lang syne.

Reading Tea Leaves to Predict the Future

Using Chladni Patterns to Create Extraordinary Classical Guitars

It may seem surprising to see this in a blog dedicated to Science and Art but it is true. My son Aaron and I regularly use tea leaves to predict the future! We are not seeking the winning numbers of the next Lotto Texas drawing, how Aaron’s romantic interests will play out, or whether it will rain next Sunday night (although that would be handy information). You see… instead of being a tasseographer, who seeks to predict the future by using superstition and folklore, Aaron is a luthier who uses science to make predictions about how his hand crafted classical guitars will sound. He is also a classical guitarist. He knows what he wants to create both visually and aurally. He knows how the guitar needs to feel in a guitarist’s hands. Yet even with all these artistic skills there is more to know when creating a high end classical guitar. Lutherie is tedious time consuming work and one mistake or bad judgment can cost you six weeks worth of time and hundreds of dollars in material costs. The bottom line is that Aaron wants to be able to know with some degree of certainty that as he carves, sands, scrapes, shapes, assembles and configures the components which eventually become a beautiful classical guitar, it will also be the best sounding instrument possible. This is where the tea leaves come in.

 How a Classical Guitar Works

Strings transfer vibrational energy to the soundboard.

The amplification of the vibration of the strings on an acoustic guitar is caused by a transfer of vibrational energy from the strings to the soundboard (the top plate to which the strings are attached).  From there it is transferred into the resonant cavity formed by the body of the guitar and into the air in front of and around the guitar. These components act very much like a loud speaker but are more complex because not only do they amplify the sound vibrations, they also add harmonic overtones which the listener interprets as the tonal quality of the guitar. The back of the guitar also contributes to the amplification to a lesser extent. All the components used in a guitar contribute to many other acoustical properties of the guitar like tone, sustain, harmonics, etc. It is the careful manipulation of several design parameters that allows Aaron to create the impressive beautiful sound of a Wood Ring guitar.

 Testing and More Testing

Testing is an essential part of the process of creating an outstanding classical guitar.

There are many processes and tests that we perform throughout the process of building each guitar that guides us toward the final great sounding product. Initially there are several tests that are used to evaluate each piece of wood being considered as a component of a guitar. Not only must the wood be visually appealing, it must have properties that are conducive to the production of the sound Aaron is looking for in his guitars. For instance, he is looking for pieces of wood that have a high strength to density ratio. This has to do with the need for the guitar to be light as possible in the hands of the player and yet strong and durable. A high strength to density ratio also allows stronger and longer lasting sound production with less energy input from the player.  He is also looking for wooden components where the internal damping of sound is minimal. This means that when energy is put into the guitar to make it vibrate, that the loss of energy to heat through internal friction is minimized.

 As construction proceeds, tests are done to guide us at each stage of construction toward the finished product. One test that we rely on is a process called Chladni testing of the soundboard. Of all the components of a classical guitar that the luthier creates, the soundboard arguably has the most influence on how the guitar sounds. The magic is in how the soundboard responds to vibrations. Sound vibrations transferred to the soundboard (either by guitar string or by loud speaker) occur as standing waves across the two dimensional surface. Since the vibrations are fast and the amplitude of the waves are very small, we must use an indirect way of seeing them. This is where the tea leaves used in conjunction with Chladni testing comes into play.

Great care is taken in the selection of the tonewood to be used as a soundboard as well as in the construction of the soundboard. We use Chladni testing to help us visualize and identify the resonant harmonic patterns that the soundboard favors. Every piece of wood used as a soundboard favors certain sound frequencies. The complete set of frequencies that a soundboard favors is like a voiceprint. It is a unique acoustic signature for each piece of wood used. It is the luthier’s job to evaluate and manipulate these signature frequencies to create a soundboard that brings out the full potential of the piece of wood that becomes a soundboard. It is the combination of these favored frequencies that experienced luthiers listen to when they tap on the wood to hear the wood’s tap tone. It is also the manipulation of these frequencies throughout the building process that helps the luthier create the optimum sounding guitar.

 Chladni Patterns

This Chladni testing process takes advantage of a phenomena called Chladni patterns. These patterns were discovered by a man named Ernst Chladni (pronounced Klahdnee) (1756-1827) who was a German physicist and musician. He has been called the “father of acoustics” because of his major contributions to the study of sound. He discovered that by drawing a violin bow across the edge of a thin plate of wood it would vibrate. When he placed some sand on the plate, he was able to create patterns by creating vibrations at different frequencies. Different patterns were created depending on the shape of the plate. See the images below.  The rectangular plate images of Chladni patterns were created by John Tyndall in 1869.  The circular plate images are from Chladni’s work on the subject.

Chladni patterns for rectangular and circular plates.

 The geometry of instruments like the guitar and violin generate patterns similar to both rectangular and circular plates. Different types of materials produce differing patterns as well. We have found that different species of woods can produce dramatically different patterns as well for a given shape. There are many variables that can affect the patterns during the testing process as well. Things like speaker location, how and where the plate is supported must be carefully controlled during testing so that repeatable and comparable results can be recorded and analyzed.

What is important to the luthier is that these patterns demonstrate visually how the sound waves travel through the plate. The places where the sand remains are the nodes of the wave pattern (where there is no vibration). The places where there is no sand are the anti-nodes of the wave pattern (where there is vibration).

Violin makers were some of the first luthiers to use this phenomena to fine tune their instruments. This process was documented in an article of Scientific American written by Carleen Hutchins a renowned violin maker who made huge contributions to the science of plate tuning of violins using Chladni patterns. This article described how these patterns can be used to guide the manipulation the top plate thickness to get an optimal sound.

Tests Performed in Crafting a Wood Ring Guitar

Our testing apparatus consists of a stand that we built for this specific purpose. It is based on a design described in the book called “Left-Brain Lutherie” by David C. Hurd, Ph.D.  David is a master at building Ukuleles. His book is a classic with regard to using the scientific method in the construction of stringed instruments. The guitar plate to be tested is placed on two tightly strung rubber bands one supporting the plate on each end. A speaker is placed under the guitar plate and is driven by a computer program which produces tones at any frequency the user desires. We place tea leaves on the plate to show the patterns. Sand, salt, glitter and saw dust have all been used to create Chladni patterns but we have found ground tea leaves to work very well for our purposes.  The full range of frequencies that a guitar can produce are scanned and the frequencies of the patterns are recorded along with the geometry of each pattern.

 The following is an image of some Chladni patterns we found for a rectangular piece of German Spruce that we will be featuring in a guitar Aaron is currently working with. This is a representative set of quality control tests that we perform on all pieces wood being considered as a soundboard for a Wood Ring guitar.  As you can see, the higher energy frequencies produce more complex patterns.

Chladni patterns recorded for a German Spruce wooden plate being considered as a soundboard.

 As the building process proceeds we again perform more Chladni pattern tests on each soundboard. We identify certain dominate patterns over the frequency range of the guitar that we can follow throughout the building process and watch how their absolute frequencies change as well as how their relative frequencies change. This information guides Aaron in the actions he needs to coax each guitar toward the sound he is seeking. The photos below show some of these patterns.

Thank You!

There are many luthiers that use the process of Chladni testing to create the outstanding guitars that are made around the world.  No one learns something this complicated without some help. Some of the luthiers that greatly influenced Aaron’s learning process are listed below. We wish to thank them for having the self confidence and generosity to share some of the knowledge they have spent so many years to develop so that others may stand on their shoulders to take lutherie to the next level.

Brian Burns – Brian’s website was influential in helping shape our testing program.  He has always been very encouraging in our correspondence with him.  Brian does consulting and also has some very nice lutherie tools for sale at a reasonable price.

Ervin Somogyi – A class act with regard to lutherie. Many of today’s luthiers have learned from Mr. Somogyi.

Luthiers of North Texas (LINT) – This is a group of luthiers who meet every two months in the Dallas – Fort Worth Area.  One member in particular, Derek Lambert, is a very good friend whose ideas, feedback and conversation in general are all greatly appreciated.

Classical Guitarists

There have been many fine classical guitarists in Texas that have been kind enough to play Aaron’s guitars and give him very candid and valuable feedback as to what they are looking for in the ideal guitar.  There are a couple that we would like to give special thanks to.

Fernand and Olga Vera – These are two dear friends that are amazing classical guitarists. Be sure and see them in concert or when they are playing at many of the local guitar festivals. Also don’t miss a chance to attend their annual workshop.

Mitch Weverka – Mitch heads up the Fort Worth Guitar Guild and has been a catalyst for promoting classical guitarists in the Fort Worth area. He also heads up the Fort Worth Guitar Guild. We are grateful to him for all the great feedback.

Cymantics – A branch of science emerged in the 1960’s called Cymatics. It is the study of visible sound and vibration. This is a field of study which was named by Hans Jenny emphasizing the intersection between art and science in the study of unseen phenomena like standing waves in various types of media. 

TED Presentation About Cymantics by Evan Grant – A wonderful talk at the TED conference in July 2009 given by Evan Grant about Cymatics (the study of visible sound). It has some great demonstrations of Chladni patterns and how this study of the substance of things not seen is being applied in research around the globe. It is for instance being used to create a lexicon of Dolphin language and is also allowing artists to create wonderful art from different music sources from Beethoven to Pink Floyd.
