I called and spoke with Hellene Hiner yesterday, creator of SoftMozart because I was looking for a trial of her program. Turns out, she has one you can link to from the main page by clicking on the yellow "TRY NOW' in the middle of the page lol I don't know why I missed it before! I told her that it doesn't look like a link, just graphic text.
Anyway, we've officially started the journey. Prior to now it has just been playing, dancing and singing to a variety of music; some youtube videos added to our playlist that mention theory; and the trial lessons from KinderBach, which he did enjoy.
So, the journey begins. All we did, since we're out of town, was practice the notes duration game last night. He liked it, but didn't quite get it. We don't have a routine that we keep while we're out of town, sadly enough, but we'll definitely add it to our schedule when we return home.
Looking forward to chronicle his progress - and Kaelie's too :-)
