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.
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.
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.

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.
