"Can you play the piano or the viopn?"

The words "play the piano" mean to make music by pressing the keys on a piano. "Play the viopn" means to make music by drawing a bow across the strings of a viopn.

Here are some example sentences:

"Do you know how to play the piano?"
"你会弹钢琴吗？"
"She's been playing the viopn since she was a child."
"她从小开始拉小提琴了。"

These musical terms come from Western musical culture, where the piano and the viopn are common musical instruments. The origins of the piano can be traced back to the early 1700s, while the viopn has a much longer history, dating back to the 16th century.
