LOS ANGELES- Only a handful of professional musicians can play it, but a rare instrument banned in the 19th century is making a comeback, and even seducing a new generation of rock and electro stars.
The glass armonica, invented by US founding father Benjamin Franklin in the 18th century, was blamed for driving musicians crazy, and is not taught in any of the world’s top conservatories.
“There are five or six of us who play it, for our own pleasure. It’s a very small community,” said Frenchman Thomas Bloch, one of the exclusive musical club.
But now Bloch has been invited by the Los Angeles Opera to play the instrument — which he jokingly says looks like a rotating glass kebab — in the Donizetti opera “Lucia di Lammermoor,” which runs until April 6.
The spelling, without an “h,” was ordained by Franklin himself, even if some have tweaked it to harmonica. It is based on the Italian word “armonia,” meaning harmony, evoking the instrument’s harmonic richness.
It is in fact a sophisticated version of an “instrument” that everyone knows: a glass filled with water, which produces a high-pitched ringing sound when a moistened finger is drawn around its lip.
Franklin got the idea after seeing musicians in London “playing” rows of glasses, filled with water to varying levels to make different notes — but wanted a more easily transportable version.
“So he asked a glass blower to create 37 bowls of different sizes, tuned chromatically over three octaves,” Bloch told AFP.
The bowls are fitted inside each other without touching and fixed on a rotating horizontal axle, the speed of which can be controlled by a pedal.
The player makes music by sliding fingers across them, moistened with a mix of water and chalk.
The whole thing looks a bit like a mixture of “a sewing machine and a translucent kebab,” the Gallic musician quipped.
The instrument was a hit as soon as it was created. France’s Queen Marie-Antoinette herself played it.
“There are believed to have been about 4,000 armonicas built between 1761 and 1835. It was played in salons above all,” said Bloch.
Mozart discovered the instrument from the famous doctor Franz Anton Mesmer — who used it to relax his patients — and liked it so much he used it for his final chamber music work.
Beethoven, Carl Philipp Emanuel Bach, Saint-Saens, and later on Richard Strauss, also composed music for the glass armonica, which was nicknamed “the angels’ organ” by Paganini.
