Mia's father. Denny also possesses a great love for music and was in a rock band of his own before he became a father. Though music was extremely important to him, his family was more so, and because of that he finds it easy to move on and "grow up". Mia and her father share a special relationship and find themselves connecting as artists. Mia appreciates who her father is, both as a musician and a lyricist. Though Denny has given himself over to the idea of fatherhood and settling down, he still clings to his rock and roll self, dressing in odd hipster fashions and playing rock music for his family in the car. Denny pushes Mia to be the best musician she can be, and shares a special connection with her. He buys Mia her first cello and gives her a pep talk before her first ever performance.
