John Langstaff http://www.revels.org/langstaff_video.html has a nice series that includes 2 videos for children. Scroll down on the Revels web site and check out ( I think) # 5 & 6. They are very appealing!
BTW, my son has an autism related disorder and we have found the computer to be the best way to reach him with music- the creations he composes on Noteworthy Composer are pretty dazzling- to us at least!
