His style was noted for very rapid runs of notes in between long lush leggato phrases in a ragtime influenced style. While he incorporated some elements of early jazz into his playing, he remained stylistically a pre-jazz artist. Some of his original compositions were hits in their day, notably Valse Erica, Valse Llewellyn, and Saxophobia.
He remained a very popular entertainer into the 1920s and performed regularly on radio, but his style started to sound more and more dated to the public as his carrer continued into the 1930s. He worked for a while in Rudy Vallee's band, then for a while in France. Rudy Weidoeft died after being stabbed by his wife.
