“After I had my baby [in January], I felt a new dimension of love which is very important for music. I really feel the power of a lot of lullabies which have beautiful power to give us safety and make us calm down. I like singing lullabies to my son.”

Released by Universal Music’s classical music label Deutsche Grammophon, Wonderworld is a compilation of 28 pieces, including classical, modern, Western, Chinese, jazz and movie tunes. Redlinger says she chose all the pieces.

“I have a deep connection to each piece. Like Schumann’s Träumerei, I played it when I was very little. Schumann played this piece in the most beautiful way. I even had the honour to play it on his original grand piano. I will never forget that experience.”

Other pieces on the album include a Sergei Rachmaninoff Prelude, a Frédéric Chopin Nocturne and Chinese music such as Ren Guang’s Colourful Clouds Chasing the Moon. Redlinger says her move to China after her marriage has enriched her understanding of the country’s music.

“I learned more about the beauty of the country. I went to many beautiful places like Jiangsu, Jiangnan, Qingdao and Yunnan. The country is so big and has such a rich variety in culture and art, like watercolour paintings. All these have inspired me a lot in my music.”

She says it was challenging to record the pieces, which are of varying styles, in 14 days but Lang was with her every day in the recording studio.

“He’s really a producer of the album and I didn’t have much experience,” she says. “It’s different from playing live. When recording an album, the microphone is very close to the piano. The sound that comes out is different than that in a live concert, where the audience in a big hall is pretty far away. I felt steady and sure when he was by my side.”

Born in Wiesbaden, Germany, Redlinger (who is 12 years younger than Lang) started to learn piano when she was four years old. Three years later, she was taken under the wing of German pianist Irina Edelstein, and began performing in public in Germany at the age of eight.

Fluent in English, German, Korean, French and Chinese, the graduate of the University of Music and Theatre in Hamburg, Germany, gave her first solo piano recital in 2009 at the age of 15. She will perform a series of concerts with an orchestra in China in 2022.

“I will play the Yellow River Concerto. I’m very excited and emotional about it,” she says.

Although their son already appears to have an interest in piano, Redlinger says she and Lang will not train him yet and instead let him enjoy his childhood.

“He really loves music,” she says. “Every time we play piano, he concentrates and is curious. However, playing music as a profession is very tough and requires much sacrifice. We have experienced it in our own lives, so we want to keep things natural.

“If he likes it, we will support it. But we won’t give him any pressure, as we want to protect his love of music.”

Redlinger says Lang is her biggest role model, noting both his talent and his dedication. “He is a top-notch pianist. But he is also very hard-working. [When] he was in Germany for a few months, he went to the master of the harpsichord Andreas Staier every day – he is always learning something new.

“He has a very challenging schedule every day. I feel like he is working for 24 hours through different continents. He quickly returns home after his concerts are finished in the evening to be with our kid.” She says it would be “beautiful” to have a second child.

“Lang is a very warm person who strives to spend as much time with the family as possible. I am very grateful to be together with them,” Redlinger adds.
