English: This is a little Etude but not easy, regarding with which the notation was from 'China National Grade Test Collection' Teaching Book. Its time-period reducing 4 empty seconds, should be 54 seconds. I preferred its 'light colours' and 'Expending & Shrinking sense of hands' fingering' frequently, like on the surface of water, thereby 'painting' (performing) it out in my studio (Classroom Live) again.

Because of my time-limitation, the first edition wasn't of my excellence. Waiting time free, I would push it to a higher level. Just, I enjoyed it very much, of which the sense was like - watching the changes of sky - from cloudy, to sunny, windy or rainy , then back... Or, it's like watching the sky from a colourful glass-window, we are praying in a church... That's to say its musicality and imagination. You knew, many piano etudes are like little flowers blooming worldwide, which can give you some beautiful and relaxable senses... Let us listen to it...

Regarding with its composer - Johann Baptist Cramer - 'a English pianist from German origin', we can search through Wikipedia.
