Bass Marimba
Built in 1988 in
collaboration with sculptor, Tim Treadwell.
The 10 sound blocks were made from 2" x 6" Clear
Redwood.
The longest, lowest pitch block is 5' long. It stands
8' wide and 3'high.
The lower 5 blocks are amplified by the large tubular
resonators mounted below.
The higher blocks are amplified by a shared "cave"
resonator.
The tuning is Harmonic Series #2-10 on C=64Hz. with an
additional block tuned to 27/64.
The lowest sound is 2 duples (octaves) below middle C.
Kosmolyre
While related to the
electric slide guitar and played similarly with a slide and plectrum, it
has much in common with harps because of the many strings on each side.
Each of the four sides are strung and tuned differently.
Side 1 has
14 strings, tuned to harmonics 4-16, with the lowest string (harmonic
#4) tripled for power.
Side 2 has 15 strings, tuned to subharmonics 3-12.
The highest string (subharmonic #3) is tripled for a chorus effect.
Side 3 has four courses of 3 strings, tuned to
harmonics 1-4. this is the "Drone" or "Pedal" side.
Side 4 (the Chord side) has 6 strings tuned to a
harmonic hexad, six tuned to a subharmonic hexad and 6 tuned in unisons
for rich melodic playing.
The instrument
can be turned easily during performance by means of the wheels at either
end of the playing board, to expose the different sides to the player.
Built by it's inventor,
Ivor Darreg in the late 1970's, it
was rebuilt by Buzz Kimball in the late 1980's. In 1992, it was restrung
and retuned to it's present state by Denny Genovese, who also designed
the stand to make it easier to play.
Hammerstrings
The Frame,
strings and soundboard of an upright piano
were mounted on an easel like stand (6' high x 5' wide).
It is played with marimba mallets, similarly to a Hammered
dulcimer.
There are 3 ranges of strings, With courses of unisons
on each pitch.
The Bass range is tuned to the subharmonic series 4-17 (a
duple lower).
The Midrange is tuned to the harmonic series 4-17 on
C=64Hz.
The highest course is tuned to subharmonics 1-12 (a duple
higher).
Harmonic Series
Xylophone
Rebuilt from a Deagan instrument,
it is retuned to a subset of the harmonic series 11-128 on C=64Hz.
Lambdoma
(subset) Xylophone
Also rebuilt from a Deagan (a
gift from Todd Underhill),
it is tuned to the subharmonic series 2-24 on G=768Hz.
with portions of several harmonic series scales as well.
Tubular Bells
The lower course of these clear
toned bells are tuned to harmonics 4-24 on C=256Hz.
The upper course is tuned to subharmonics 2-12 on G=1536Hz.
Lambdoma Chimes
These Capped, chrome plated brass
tubes ar tuned to Harmonics 6-16 on C=64Hz.
and to subharmonics 3-11 of G=768Hz.
Big Drums
These drums put a solid bottom on
rhythmic episodes.
They were built by Denny Genovese around 1991.
Hand Drums
For extra rhythmic interest.
The two on the far left were built by Denny Genovese around
1990.
Roto-Toms
Each of these 3 drums are easily
tuned to various schemes by rotating them.
Fretless Guitar
and Bass
Interchangeable Fretboard guitar

The guitar was a gift from my brother Gary. I purchased an
interchangeable fretboard kit from Mark Rankin and hired Buzz Kimball to install
it. I designed and calculated the fret positions, and Buzz helped me create the
magnetic fretboards, that slide on and off of the steel plate on the face of
the neck. Frettings include: 5 Limit Just, 17 Limit Lambdoma, Fretless. It
also works as a slide guitar when no fretboard is used.
Fipple Pipes

Harmonic series scale is played by changing breath pressure.
each length has a different fundamental frequency.
Accidently invented in 1977, several hundred were made over
about 15 years thereafter.
Theremin Controlled Analog Synthesizer
(photo by John O'Brian)
The control voltages from a Paia Theremax theremin (donated by
John Simonton) are routed to a set of ARP 2500 analog synthesizer modules
(donated by Don Slepian). The pitch is controlled by moving the left hand toward
the vertical antenna, and the loudness and timbre are controlled by moving the
right hand toward the horizontal antenna.
These Instruments are currently Located at the Florida School of
