Music theory major Molly McCahan was only 5 years old when she started taking piano lessons, and she was singing and dancing even earlier. The daughter of music-loving parents, McCahan grew up surrounded by song in her Plymouth, N.H., home. By the time she was considering career paths in high school, her talent and passion for music were deeply rooted. Pursuing it in college seemed a natural choice. Her older sister was already happily studying music at UNH. The younger McCahan decided to follow.
