Learning, sharing knowledge and being part of the classical guitar community are important to me. Although I don't have time to teach hands-on in the workshop, I am enthusiastic about teaching builders and players through lectures, writing, podcasts and videos. Below, you will find a variety of topics that I have shared with builders, guitarists and non-musicians alike at universities, guitar societies and international forums. If you are interested in hosting an event for your group, please contact me.

Guitarists, Luthiers and Physics was a guest lecture presented in the course Physics 115, The Physics of Music at Wake Forest University on  Apr. 9, 2024. The lecture gives an introduction to how luthiers satisfy the needs of players within the constraints of the laws of physics. The lecture was recreated on video here.

Essential Knowledge for Guitarists is a presentation developed for guitar teachers and undergraduate and graduate guitar performance majors that teaches essential information about owning, playing, and purchasing guitars. 1) What controls action? 2) What controls intontation 3) What is fingerboard relief and why do I need a little, but not a lot? 4) How do different strings affect sound and playability? 5) Why is humidity important?  6) Cases and travel.

Controlling Resonance and Tone Quality through Structure is a presentation for beginning through advanced luthiers designed to provide an understanding of the physical basis for controlling guitar sound and consistency. Starting with principles of resonance and the structural and mechanical variables that influence it, this presentation provides the conceptual and practical means for a builder to alter a guitar’s voice.

Past Presentations:
    3rd International Forum of Lutherie, Asuncion, Paraguay Oct. 2016


Controlling Sound gives players a fascinating look into what real lutherie is about—getting the sound. The presentation introduces acoustic and structural concepts in a fun and painless way through demonstrations. The presentation delves into what hand builders do to pull out every drop of sound using materials, design and execution. This session will answer questions such as: 1) what makes a luthier-built guitar sound so much better than a factory-built guitar? 2) why do spruce guitars sound different than cedars? 3) how does a guitar’s structure determine its sound? and 4) what are the current trends in guitar building? This is the most interesting talk for avid amateur players (such as in guitar societies) and college through professional players.

The Intersecting Worlds of Luthier and Player starts with Gary interviewing a professional guitarist about his/her relationship with the instrument, giving the guitarist an opportunity to discuss and demonstrate the musical/playable qualities of a concert-level guitar and the realities, joys, frustrations of a the guitar as a tool of the trade. The brief discussion is followed by a more formal talk on how I as a builder fulfill these needs. The presentation explores traditional and contemporary features on classical guitars and how players’ needs influence the type of guitars luthiers build. This talk is more about design, structural and acoustical concepts and less about how guitars are built step by step. The presentation can be modified to include the type of basic info that someone might like to know if they are going to buy a guitar. This talk has been the most popular for hard-core guitarists as well as non-musicians and is particularly inviting for audience questions and extended discussion.

Confessions of a Luthier gives an inside and personal look into lutherie as a profession and the lessons learned from players and the craft.
Sample Description: A professional luthier wears many hats: craftsman, businessman, acoustician, engineer, musician, research scientist, and sometimes psychotherapist to the player. Join luthier Garrett Lee for an inside look into the world of classical guitar building as a career. Having observed hundreds and hundreds of guitarists play an equally large number of different guitars, Gary has had the unique opportunity to observe how different guitarists interact with their instruments. What are concert players really looking for in a guitar? How does one start building guitars and what does it take to do it professionally? Where do you get all that wood? What is the hardest part about building guitars and is it really possible to control such a complex system? Learn the answers to these questions and more through a different perspective on the world of classical guitar.

What Does a Luthier Do in the 21st Century? is designed for general audiences and illuminates the many facets of being a luthier in the modern world. More than just a description of what I build, I delve into the questions that have defined my career in instrument making: why and how did you transition from a career in science?
