One of the great jazz pianists of all time, James P. Johnson was the king of stride pianists in the 1920s. He began working in New York clubs as early as 1913 and was quickly recognized as the pacesetter. In 1917, Johnson began making piano rolls. Duke Ellington learned from these (by slowing them down to half-speed), and a few years later, Johnson became Fats Waller's teacher and inspiration. During the '20s (starting in 1921), Johnson began to record, he was the nightly star at Harlem rent parties (accompanied by Waller and Willie "The Lion" Smith) and he wrote some of his most famous compositions during this period. For the 1923 Broadway show Running Wild (one of his dozen scores), Johnson composed "The Charleston" and "Old Fashioned Love," his earlier piano feature "Carolina Shout" became the test piece for other pianists, and some of his other songs included "If I Could Be with You One Hour Tonight" and "A Porter's Love Song to a Chambermaid."
