John Briggs, 65, of Little Lane in East Morton, near Keighley, is accused of five offences involving three alleged victims, two of them under 16 and the third a male over 16.
The offences are alleged to have taken place in the early 1990s.
He faces four charges of indecent assault and one of gross indecency with a child.
Briggs appeared before Bradford and Keighley Magistrates’ Court where he was granted unconditional bail. He is due to make his first appearance at Bradford Crown Court on Tuesday.
Briggs is a world renowned classical pianist and composer who has played at concerts across the globe, including at New York’s Carnegie Hall and on the edge of the Grand Canyon, a performance which required a helicopter to deliver the grand piano.
In 2011, 20 years after the original Grand Canyon event, he repeated the performance.
The Bingley-born musician has toured extensively and was made an MBE in 2003 for his community work.
