In all, the American composer Henry Cowell composed 20 symphonies, and left sketches for a 21st.

On today’s date in 1954, the Louisville Orchestra gave this premiere performance of Cowell’s 11th Symphony, subtitled “The Seven Rituals of Music.”

“There are seven rituals of music in the life of man from birth to death,” Cowell explained in program notes for the Louisville Orchestra’s recording of the new work, made shortly after their premiere performance. According to Cowell, these musical rituals included work, play, dance, love, and war, bracketed by the mysteries of birth and death.

The mood and mysticism of Cowell’s programmatic Symphony are similar to those found in Gustav Holst’s much more familiar orchestral suite, “The Planets.”

Although interest in Cowell’s music has risen steadily since his death in 1965, performances of Cowell symphonies are still rare events. Part of the problem lies in the eclectic range of styles to be found in Cowell’s music, and his fascination in what we now call “world music.” There is, for example, a Cowell “Gaelic” Symphony, another entitled the “Icelandic” Symphony, and yet another, influenced by Indian ragas and talas, entitled the “Madras” Symphony.

This didn’t bother Cowell at all. As he once explained it: “I have never deliberately concerned myself with developing a distinctive personal style, but only with the excitement and pleasure of writing music as beautiful, as warmly, and as interestingly as I can.”
