WASHINGTON—Of all the great things that can be named of Shen Yun Symphony Orchestra’s qualities—the music, the timing, and the musicians’ professionalism—none was more impressive and inspiring than the words sung by Shen Yun vocalists for some in the audience.

“There were inspiring thoughts about mankind and hope for mankind. And that was delightful” said Lowell Christensen, an engineer, who was back for his second experience with Shen Yun Symphony Orchestra at The Kennedy Center Concert Hall after seeing it the year before.

For Gary Stradling, a physicist, the lyrics likewise were very inspiring.

“I really resonate with the lyrics of the songs. And I thought they were bringing our minds to things that were important. And the music that went with them was important,” said Mr. Stradling.

While vocalists sing in Chinese, the lyrics of the songs, along with their English translations, are projected onto the digital screen.

“The singers were very talented and powerful,” said Mr. Stradling.

Mr. Stradling said he walked away from performance with a great feeling and he would have a good memory of what he saw today. What’s more, he explained that he became aware of how much some overseas Chinese wish to see peace and harmony in China one day.

As for Mr. Christensen, he said he would be back again next year for the performance, and might go to see the Shen Yun’s flagship dance company in January.

Shen Yun Symphony Orchestra will put on its last performance on Oct. 29 before joining Shen Yun Performing Arts’ touring dance companies for global performances starting in December.
