I've played the piano for nearly 20 years and the drums for 10 years or so. What's great about the drums is it's role in a band, as it is the glue to each song, keeping the tempo and adding that, simply put, awesomeness to each song. What's great about the piano is it's ability to reach people emotionally. It is a unique instrument that, simply by it's sound, can have people pondering deep thoughts, crying or celebrating. My greatest achievement in playing the piano is the ability to write original material.
