One of our class excursions was a trip to the Musée des Arts et Métiers. While here, I came across a section dedicated to musical instruments. It took me back to my childhood days of playing the violin as well as the simple fact that music is such a significant part of this generation. Seeing one of the first iPods in the museum made me gasp a bit actually. What many people might not realize about music, or practicing tasks in general, is that the more you use something (say, your fingers to play the cello), the better your brain gets at remembering the task. This is because the cortical representation of a task expands with repetition (Purves, 5th edition). So, if you want to be the next Yo-Yo Ma, you better get back to your lessons!
