Emánuel Moór (19 February 1863 20 October 1931) was a Hungarian composer, pianist, and inventor of musical instruments.
Moór was born in Kecskemét, Hungary, and studied in Prague, Vienna and Budapest. Between 1885 and 1897 he toured Europe as a soloist and ventured as far afield as the United States. Besides five operas and eight symphonies his output also included: concertos for piano , violin , cello , viola, and harp; a triple concerto for violin, cello, and piano; chamber music; a requiem; and numerous lieder. He died, aged 68, in Chardonne, Switzerland.
His best-known invention was the Emánuel Moór Pianoforte, which consisted of two keyboards lying one above each other and allowed, by means of a tracking device, one hand to play a spread of two octaves. The double keyboard pianoforte was promoted extensively in concerts throughout Europe and the United States by Moór's second wife, the British pianist Winifred Christie.
Maurice Ravel said that the Emánuel Moór Pianoforte produced the sounds he had really intended in some of his works, if only it had been possible to write them for two hands playing on a standard piano. Pablo Casals always believed in him and often played his works.
Moór and Christie also collaborated on a book of technical exercises for the instrument. Text source : Wikipedia (Hide extended text) ... (Read all)
