Daniel Ruyneman

Before the war he established and edited Maandblad voor Hedendaagsche Muziek (Contemporary Music Monthly Magazine), which was banned during the German occupation of the Netherlands.

[2] He was initially influenced by Grieg, Debussy and Ravel, followed neoclassical trends (in pieces such as the Partita for Strings, 1943 and the Nightingale Quintet, 1949), produced some large scale romantic works (such as the Violin Concerto), and towards the end of his life experimented with serialism in the four Réflexions (1959-1961).

[4] His interest in Javanese music led to the invention of the Electrophone, an instrument consisting of various electric bells, playable from a keyboard.

The unique cup-bells used for this were (according to some), specially cast by the bell foundry of John Taylor & Co of Loughborough, England, though others say they were found by the composer in a London junk shop.

However, the Electrophone was destroyed during World War II in an air raid on Rotterdam, so subsequent performances have substituted vibraphones.
