ORACLE:
24-STRING HARP-SYMPITAR
completed January, 2002
Oracle is a 24-string Harp-Sympitar, commissioned by (San Jose area) software
writer and guitarist Jeff Titus. Jeff's inspiration was a combination of
the harp-guitar work of the late Michael Hedges, and Alex de Grassi's use
of the 18-string Sympitar.
Jeff intended the instrument to be a loving tribute and dedication to Michael
Hedges. The spiral and arrows inlay motif used on the back of the instrument
and as an inlay at the 12th fret of the fingerboard, is the property of
the Michael Hedges Estate, and is used with permission.
Oracle was built to be primarily acoustic, but
is fully amplifiable and midi-capable; each set of strings has a separate
pickup system with separate output jack. It has 6 main, fretted strings;
6 sub-bass harp strings on a bass-side body extension with separate peghead;
and 12 internal sympathetic resonating strings. As with my 18-string Sympitar,
the internal sympathetics run inside the neck, inside the body and go over
an East Indian style "jiwari" bridge, that gives them a little
buzz: that Indian drone sound. The spiral and arrows inlay (done in fine
maple purfling line) on the rosewood back delineates a magnetically closed
access door, useful for replacing or adjusting sympathetic strings, internal
electronics and for repair access. 
Oracles' unique shape is a rethinking of the old
Dyer style harp guitars, such as Hedges played. In designing it, we wanted to
create a much more ergonomic instrument, something relatively easy and comfortable
to play, as well as a sculpture with a flow, balance and intriguing movement
to the lines. And of course we wanted a balance of sound where the sub-bass
would be warm, full and project well but not overwhelm the main strings.
The tuning is variable: open tunings work spectacularly
with the internal sympathetic strings and the massive sympathetic response
from the sub-basses. We initially set it up in standard tuning on the main
strings, using Elixer Custom Lights;
with a sub-bass tuning of: (lowest to highest) E G A B C D with phosphor
bronze strings at .077", .064", .060", .056", .056",
.054" respectively (the sub-bass string lengths start at around 32"
for the low E, and get progressively shorter). The low E and G sub-bass
are acoustic bass strings with 1/4" ball ends; at the bridge these
have larger holes and pins made from ebony endpins. This was done to allow
for the potential use of very heavy-gauge acoustic bass strings available
only with the larger ball ends, in case one wanted to lower the range of
the sub-basses significantly. The 12 internal sympathetic strings can be
tuned chromatically, but give the strongest effect when to tuned to the
specific mode or key being played in, doubling up notes where one wants
a greater response. For more on sympathetics see the Sympitar
page.
Oracle is a great example of how building a unique custom instrument for
someone always takes me to places I would never have imagined going on my
own. Although I often find myself wanting to influence a project with my
own tastes and vision as much as possible, when I let go of my desire for
control and work to try and find a place where my client's vision and mine
can thrive together, magic happens. I always learn so much from these kinds
of projects; it feels like such a gift I'm being given, even if sometimes
in the thick of struggling to get something to work I lose sight of that
perspective.
After a couple of days playing the finished instrument,
Jeff felt that it begged for open tunings, in which it sounds so beautiful
that he now doesn't anticipate playing it in standard at all.
