People have compared the cello’s sound to the human voice for centuries, which is probably why it sounds so appealing to our ears.

Playing cello means you get to play almost every part in the orchestra: the melody, harmony, and bass line, often all in one piece. Pablo Casals a world famous cellist from the 20th century when asked why he continued to practice at age 90 replied: “Because I think I’m making progress.”
