Hatchidori Wa Hana Ka[ra] Hana [e tobu] (Hummingbird Flies from Flower to Flower) and Kabutomushi (Rhinoceros Beetle) are musical pieces that attempt to capture the energy of the natural object; in this case, a hummingbird and a rhinoceros beetle. I believe staying true to the spiritual origins of Koto is paramount.
Spiritually, Koto jazz seeks to bring out the Japanese Shinto-Buddhist spiritual nourishment derived from connection and reverence to nature as well as ancestral worship. The western influences of jazz music, in part, have their origins in western Judeo-Christian ideals and institutions. It is my opinion we need to bring these two together into an harmonious whole of “yin and yang”, bringing out the best in both traditions which lifts us to broader spiritual growth and learning.
The best written description/ representation of this that I’ve read to date is the a #1 New York Times Bestselling book by James Redfield called The “Celestine Prophecy“, and our evolution toward a global non-religious spiritual awakening.
