Leonard Bernstien: Harvard University Lecture 'The Poetry Of Earth'

Bernstien talks about the tonal composers of the 20th century classical contemporary music. Starting from Stravinsky, he expands towards other composers and also gets into the concept of poly tonality and poly rhythm which I believe Charles Ives came up with before any other composers. This is the final lecture of the six lecture series where Bernstien finishes of with the tonal composers which is immediately preceded by non tonal composers, kind of a like the Unanswered Question of Ives where the piece ends with the everlasting diatonic G Maj triad.

This lecture was titled The Poetry Of Earth
