Music for strings and
Seven musical pieces for five robot instruments: two violins,
a viola, a cello and a drum.
The electro-acoustic instruments use pneumatic micro-pistons
fired by a midi program to determine the
pitch of the strings.
has two kinds of pizzicato (piston) and
two e-bows (a system of changing-polarity electromagnets),
keep the strings in resonance and produce an infinite sustain.
They do the same as
a traditional bow with a string instrument.
The sound is amplified
and post-produced using synthesisers.
Written by the Australian composer Elena Kats Chernin,
the seven pieces has been commissioned by the German company
Festo and were premiered in April 2007 to
mark the 50th anniversary of the Hannover Industrial Fair, in the presence
of German Chancellor Angela Merkel.
