The lists of music recommendations that I am providing in the Repertoire Secton of Musical Kaleidoscope are the result of research that I began in 1969, after realizing that at the beginning of the 20th century, the harmonic structure of our classical music had begun changing from one that was concord-based to one that was based on discords, and that a new music was then emerging that would soon provide the background for the destructive exploitation that took place during the 20th century, creating conditions that are now widely recognized as extremely dangerous: atomic energy, deadly missiles, poisoned food and water, mass brainwashing, financial disaster, and the destruction of natural habitant and the climate. I believe that all of this was clearly forecast in such early 20th-century music compositions as Anton Webern's Six Pieces for Orchestra, composed in 1909: music that is filled with foreboding and the cold metallic energy of the coming century; music based on the square of materialism instead of the triangle of harmony.
In 1969, I began what I now call "Don Robertson's Music Revolution." This revolution is about returning to the harmonic principles of nature - shifting from the discordant music created during the 20th century to the concord and pure harmony that exists in all traditional music. During that year, I began a very thorough study of music to determine which music compositions, in my opinion, had true greatness, according to the music's inherent spiritual and/or emotional relevance. I continue to work on this study today. The Repertoire Section of Musical Kaleidoscope presents a subset that represents the results of my study: over 45 years of intense research...recommendations for listening, study, enlightenment, upliftment, and enjoyment.
