Abstract
The Symbaline is an active instrument comprised of several
partly-filled wine glasses excited by electromagnetic coils.
This work describes an electromechanical system for incorporating frequency and amplitude modulation into the Symbaline’s sound. A pendulum having a magnetic bob is suspended inside the liquid in the wine glass. The pendulum is
put into oscillation by driving infra-sound signals through
the coil. The pendulum’s movement causes the liquid in
the glass to slosh back and forth. Simultaneously, wine glass
sounds are produced by driving audio-range signals through
the coil, inducing vibrations in a small magnet attached to
the glass’s surface and exciting glass vibrations. As the
glass vibrates, the sloshing liquid periodically changes the
glass’s resonance frequencies and dampens the glass, thus
modulating both wine glass pitch and sound intensity
