The Music Moose site (http;//www.musicmoose.org) offers free music lessons.Â
Members graciously post videos of lessons on a variety of instruments. Here’s a good example of the power of the internet being used for good. They launched last summer, and have several lessons up, and over 500 members.  The site is community-driven , and they welcome contributions and help. Their site has more information on how you can help out
