Current Projects
New Book Writing Project
​This website is going down a different direction. I am currently transferring all this experience and data into a book writing project. The attempt is to document all my bar percussion projects, processes, materials, and musical technicalities used in this lifelong endeavor.
​
This book is an exhaustive photo and technical opportunity to explain and present the wonderful, tricky at times, and the never-ending romance of a really cool percussion instrument and subject.
(Heavily into the Research and Writing phase right now.)
Aiming to have it [eventually] available on Amazon.com
New Instrument
5-Octave Marimba
Range: C2 to C6 (C2, C3, C4. C5, C6)
No. of Notes: 49
Bars: African Padauk
Resonators: Baltic Birch Plywood - Column
(*Half-Wavelength: open at both ends)
​
---Space reserve for new drawings---
*HALF-WAVELENGTH RESONATORS
PROS - Since both ends are open, the resonance emanates from two points, which essentially makes the sound twice as loud. And, half-wavelength has the benefit of causing ALL harmonics to ring along with its fundamental frequency.
CONS - This resonator must be twice as long, which could be challenging in its shape and placing its additional size beneath its bars in the lower region of notes. Multiple resonators can easily lead to placement problems and crowding which could lead to misalignments between the bar and resonator opening. This design will be very challenging to say the least! Stay tuned...

QUARTER-WAVELENGTH RESONATORS
​
PROS - Since only one end is open (and the other end is stopped) this shorter length is easier in managing fit issues of many resonators beneath their respective bars.
CONS - The stopped end only allows for the odd harmonics to resonate along with its fundamental through the open end. Odd harmonics are not as "sweet" sounding as all harmonics sounding (simultaneously) in the half-wavelength version. You have to "hear the difference" between the two to understand the nuances between these two resonator systems.
