aim:

- an interface with which electronic sound devices like synthesizers and samplers can be controlled through midi (diverse sensors)
- a new form of instrument that allows musicians to perform entertaining shows through physical presence on stage (typically the part of the vocalist and guitarist in the "classic" rock show)
- an attractive, fashionable solution that lives up to the expectations of a modern musical instrument

conclusion:

WEARABLE MUSICAL INSTRUMENTS

there exist midi guitars, known rock music instruments that can be utilized to control music software

there exist wearable computers, wearable communication tools like mobile phone scarfs, hats with embedded speaker systems...

existing wearable musical instruments:

"Audio Ballerinas" by Benoît Maubrey and Die Audio Gruppe

"CosTune" the wearable input device is a cloth (e.g., jacket, pants and gloves) on which a number of tactile sensors that correspond to, for instance, keys of a piano are mounted.
"CosTune was designed to be a communications tool rather than a simple musical instrument."

IDEAS

an example for a sequenced software synthesizer
the interface should allow the control of all essential parameters

fashionable accessories that allow the implantation of sensors

the belt, one of the most popular fashion accessoires of today, allows the implantation of several different sensors like touch, flex, bend, pressure sensors, knobs and sliders.

suspenders, a classical male fashion accessoire, invite to be equipped with stretch sensors

implanting stretch sensors into these kind of suspenders would certainly be especially entertaining

thoughts:

the big disadvantage of simply implanting small sensors into clothes is the cable problem. as long as no high-tech wireless technology is used the performer will always be attached to a cable.
the advantage of being attached to a cable is that no devices except the sensors have to be carried on the body.
