Which of the following was NOT a popular music activity in the eighteenth A. Playing lute B. Playing chamber music. C. Playing piano D. Hearing a composer play his own work.

In the eighteenth century, the lute was still played, but its popularity began to wane as other instruments rose to prominence. During this time, chamber music flourished, especially among the rising middle class who enjoyed intimate gatherings where music was performed in small groups. While the piano was gaining traction and becoming a staple in households, it wasn't as universally popular as the other activities listed, particularly since many composers preferred to perform their own works, captivating audiences with their original pieces. Hence, hearing a composer play their own work was a significant part of the musical landscape, unlike the declining interest in the lute.
