Play on like Ludwig van Beethoven

"The dynamic trio is back! When their friend Gordie is about to give up on math class (what is it with Xs and Ys, anyway?), Lucky, Rudy, and Red take another trip back in time to meet Ludwig van Beethoven. After all, if anyone can help Gordie persevere, it's the man who composed his greatest music even after losing his hearing. Can Gordie find the perseverance to push through?"--Provided by publisher.
