The Tenori-on is an electronic musical instrument designed and created by the Japanese artist Toshio Iwai and Yu Nishibori of the Music and Human Interface Group at the Yamaha Center for Advanced Sound Technology. It consists of a hand-held screen in which a sixteen-by-sixteen grid of LED switches are held within a magnesium plastic frame. Any of these switches may be activated in a number of different ways to create sounds. Two built-in speakers are located on the top of the frame, as well as a dial and buttons that control the type of sound and beats per minute produced.
There are two versions of the device available. The original TNR-W (Tenori-On White) features a magnesium frame, 256 rear panel LEDs and can run on batteries whilst the more affordable TNR-O (Tenori-On Orange) features a white plastic frame, has no rear LEDs and does not take batteries. The modes and sound sets in these instruments are the same.
Both devices have an LCD screen on the bottom edge of the frame. Using the connection function, it is possible to play a synchronized session, or to send and receive songs between two of the devices.
Tenori-on was demonstrated at SIGGRAPH 2005 held in Los Angeles, CA in August, 2005. A detailed discussion of the design of the Tenori-on is given in a paper presented at NIME 2006 conference held at IRCAM, Centre Pompidou in Paris, France in June, 2006.
Toshio Iwai has been using the Tenori-on in live performances (such as at Sónar in Barcelona, in June 2006, and Futuresonic in Manchester, in July 2006, the Futuresonic 2006 live show had some good feedback from the audience and that was one of the most important triggers to make it a real product). The instrument was launched in London on September 4, 2007 for a recommended retail price of $1,200 (£599). To promote this launch, three prominent electronic and experimental musicians -- Jim O'Rourke, Atom Heart, and Robert Lippok—were invited to compose "demo" tracks utilizing the device. These tracks have since been released as promotional MP3s from the Tenori-on website.
Iwai's intention in creating the Tenori-on is to create an electronic instrument of beauty. In his own words:
- "In days gone by, a musical instrument had to have a beauty, of shape as well as of sound, and had to fit the player almost organically. [...] Modern electronic instruments don't have this inevitable relationship between the shape, the sound, and the player. What I have done is to try to bring back these [...] elements and build them in to a true musical instrument for the digital age."
A World Tour introducing Tenori-on began in Frankfurt, Germany, on March 12, and finished in Tokyo on 25 April 2008. Artists on the tour included Jim O'Rourke, Atom Heart, To Rococo Rot, Pole, Robert Lippok, Sutekh, The Books, Krikor, Safety Scissors, I Am Robot and Proud, Lou6Journey and Nathan Michel.
