The pianist also recorded one of her original pieces, titled Encore, for the new album, which she describes as delivering a sense of feeling-illusory and vague.

She says living in China has enriched her understanding of the country. Chinese music also inspires her. Redlinger has also included Chinese music, such as Ren Guang's Colorful Clouds Chasing the Moon, on the album.

"I have always had a deep affection for Chinese music, which is like watercolor painting, and after moving here, I traveled to many beautiful places and learned about Chinese culture," Redlinger says. "My husband plays Chinese music at home and he also told me lots of stories about it."

She adds that next year, she plans to perform Yellow River Piano Concerto during her Chinese tour. The piano concerto was arranged in 1969 in a collaboration among Chinese musicians, including Yin Chengzong and Chu Wanghua, and is based on the Yellow River Cantata by Chinese composer Xian Xinghai.

The album closes with Lang and Redlinger's four-handed performances of Johannes Brahms' Hungarian Dance No 5 and Waltz Op 39 No 15. The latter is dedicated to their son, who was born in January.

"Our son has already shown great interest in piano. Every time we play at home, he will search for the sound and come to us," says Redlinger. "It's not easy to keep a regular daily practice schedule, because being a mother means a lot of work taking care of the baby. However, becoming a mother has certainly helped me to better understand music."

The pianist was born to a German father and a South Korean mother in Wiesbaden, Germany. She started to learn the piano when she was 4 years old and began giving public performances in Germany at the age of 8. She studied at the Academy of Music and Performing Arts in Frankfurt and later became a student of renowned pianist Gary Graffman at Hamburg's Academy of Music and Theater. After graduation, she played with several Chinese orchestras, including the Shenzhen Symphony and the Guangzhou Symphony.
