For years I'd often wondered what happened to Andre Tchaikovsky, a gifted young Polish pianist I had heard in the late 1950s play Prokofiev's propulsive Second Piano Concerto with inflammable virtuosity. Grove had his bio, which showed he died at 47 in 1982. Clicking on a link for further exploration told me that Tchaikovsky became infatuated with Shakespeare while living in London, but that he also evolved into an accomplished composer whose Piano Concerto was played by Radu Lupu and the Royal Philharmonic. You can also click up musical illustrations and tap into sound links that let you listen to examples. Some things can be found immediately.
Grove also helps with marginal terminology.
He was a civil engineer who built lighthouses in the West Indies and helped develop the British railway system. He explored Palestine, spent several years editing Smith's Bible Dictionary, and authored a geographic textbook besides his great musical dictionary. It was Stanley Sadie who finally brought Grove into the 20th Century with the so-called New Grove I in 1980. He recruited 2,400 first-rank scholars from 70 countries to create 22,500 new articles bound in 20 volumes. Now he has done it again.
