This Akio Yamamoto creation consists of two pieces fashioned after the image of intertwining Bach melodies. Following the dynamic build-up is an inspirational finale when the two pieces elegantly release from each other. You may even want to choose a somewhat luxurious and relaxing ambience when attempting this puzzle. The key word is "music."
