Douglas made his concert debut in St. Louis at the age of 16. He polished his playing to gem-like brilliance through studies at the Juilliard School (this was before they even had a guitar program), the Segovia Master Classes in Spain, and with Christopher Parkening, Narciso Yepes, and Jorge Morel. He made his New York debut at the age of twenty-one in Carnegie Recital Hall. Doug began teaching the guitar at the age of 13 and has taught ever since while maintaining a busy concert career. Recognized as a master teacher, he is the retired chair of the guitar program at the University of Missouri-Kansas City, Conservatory of Music and Dance. He operates douglasniedt.com, a website dedicated to classical guitar education and instruction. It includes the world's first Classical Guitar Technique Wizard, an AI chatbot dedicated to classical guitar technique. He recently developed the TremoloMASTER, a course to master the tremolo.
