I have often suggested to parents that they look on youtube for good videos of people playing repertoire their children are trying to learn. It's a great inspiration for music students, especially when you can find a child of a similar age playing with good habits. As always, and particularly on Youtube, be sure to supervise and pre-watch anything you show your kids.

Here are a few things my boys (ages 3 and 5) have really loved watching:
The Cello Wars

Infinitus "Anthem" This is a beatboxing string trio fronted by John "Adidam" Littlejohn, a friend of mine from Peabody who runs a not-for profit music academy that serves underprivileged kids.

So don't forget Youtube and other video posting sites as a great resource for practicing inspiration.

Happy musicmaking!
