This album is made up of eleven pieces chosen by five composer/pianists with a great love for the piano, all working on one theme. The theme is as the title, the "Ancient City". When we say the Ancient City, we think of Kyoto. For a thousand years until the capital was moved to Tokyo, it served as the center of the Japanese culture as its imperial capital. As you can see from the fact that 20% of the national treasures and 15% of the important cultural assets are concentrated in Kyoto, it has been the city of creativity and culture since the Heian Era. As for the musical aspect of the culture, imperial music was developed based on the pentatonic scales that was quite probably imported from China, then re-arranged into Japanese style. This was to become the Japanese scale.
