Bill Douglass lernte ja von Cozy Cole. Douglass hat viel später bei Drum City Unterricht gegeben. Cole hatte eine Drum School mit Krupa zusammen, allerdings in New York.
Douglass never took private drum lessons, but eventually made the acquaintance of Cab Calloway drummer Cozy Cole, who used to allow Douglass to watch him practice. Douglass learned a lot watching Cole and other drummers, who gradually helped him evolve a style of his own.
