Scott Joplin's New Rag. Composed in 1912 by Scott Joplin himself, this ragtime is very fast and closer to Tin Pan Alley in style than his own usually slower compositions. In section C there are suggestions of stride piano which is later adopted by among others Fats Waller. Solo Score. Pure Duo Sheet Music, Arrangement for Trumpet and Bb Instrument by Lars Christian Lundholm.
