Estaría bien tener algo más de tiempo libre para dedicárselo a cursos como History of Rock, Part One, impartido por John Covach para Coursera:
This course, part 1 of a 2-course sequence, examines the history of rock, primarily as it unfolded in the United States, from the days before rock (pre-1955) to the end of the 1960s. This course covers the music of Elvis Presley, Chuck Berry, Phil Spector, Bob Dylan, the Beatles, the Rolling Stones, Jimi Hendrix, Cream, and many more artists, with an emphasis both on cultural context and on the music itself. We will also explore how developments in the music business and in technology helped shape the ways in which styles developed.
El curso parece ser gratuito, tiene una duración de 7 semanas con una dedicación requerida estimada de 2 a 4 horas semanales.
