Modal Tuning with Trevor Gore
In July 2022 Luthier Trevor Gore, from Sydney, Australia, will once again come to the O’Brien Guitars shop and share his knowledge and experience with Modal Tuning. After having to postpone Trevor's Modal Tuning class for the last two years due to covid restrictions, we are pleased to offer this class again for most likely the final time.
This is a rare opportunity to study with an expert in the field of guitar acoustics and design. Trevor's classes always fill quickly. You will not want to miss this class. We are offering two sessions: July 15-17 and July 19-21. The cost is $1800. There are just a few spots left in each class. If interested contact me to get on the list of participants and also let me know which class session you prefer. I will try an accommodate your request but can't guarntee it due to high demand for Trevor's class.
Topics covered include:
- How strings drive your guitar
- Visualizing and understanding modes of vibration
- Relating modes of vibration to guitar frequency response curves
- Measuring frequency response curves
- Relating frequency response curves to generic guitar types (classical, flamenco, steel string rhythm, steel string finger picking)
- Introduction to theory of modal vibrations
- Mechanical impedance and admittance
- Targeting the “right” modal frequencies and avoiding the wrong ones
- Requirements of a guitar as a static and dynamic structure
- Measuring material properties so that you can make the best of the wood you have rather than wishing for the wood you would like
- Bracing schemes for backs and tops
- Practical tuning of guitar modes: Moving from “as built” to “to design”
$1800
