His piano pieces are lively and melodious, but also sometimes melancholic (like Solace and Bethena Waltz) perhaps reflecting the troubled life he led. As the article states, Joplin did not want his rags to be played at fast speeds. This is often the case in many recordings (including, in my opinion, with Joshua Rifkin). My favourite performer of Joplin's music is the late Canadian musician John Arpin.

But wherever you start with Joplin's music, the sound of a rag is irresistible.
