Another one of my students, twins David and Nina, performing a tune they wrote themselves. It's pretty good and catchy, in my opinion. I started giving them lessons at the ages of 7, and their progression on their instruments was pretty impressive. With the support and encouragement of their parents, and constantly listening to music, they not only were able to start playing well early on, but were also writing their own songs and having their dad record them on his computer. Awesome, I say!
