Travis Brown has studied music and music theory for over 20 years. Having learned and practiced multiple instruments, he began teaching others to play various instruments. He has been a private instructor for the past 10 years. Travis believes in teaching students strong fundamentals and appreciation of music, followed by advanced studies in complex music theory concepts for composing, improvising and songwriting. This music theory book was developed using the techniques and knowledge that he has learned and taught to hundreds of his students. He has also created several other tools to aid in the learning of music theory including eVirtuoso® Intermediate, an interactive computer program designed to help aspiring musicians learn, create, and improve musical development and eVirtuoso Scheduler, an intuitive web site that allows flexibility and collaborative tracking with teachers and students to organize lesson arrangements.
