I bought the program not too long ago and so far I really like it. Because I am still waiting on my usb cable I have only been able to play some of the games, but I did meet with one of the doremifasoft teachers from the website, Juliann French, and along with an introduction to the program we also were able to experience the actual songs from the playlist.
The thing that sold me to the program was the different levels that the program has and the method used to introduce those interested to the piano. I have always wanted to learn and this program makes it so easy for me to do along with my son. He loves playing the games and asks for "piano" every chance he gets. He is getting the hang of the games and getting better and better the more he plays them, but we also do finger exercises just on the keyboard to get him familiar with the sounds, do re mi fa so la ti do, and getting him comfortable with using all of his fingers to play. I played my first song along with my son for the first time with Juliann and I knew from that point that with consistency and hardwork we both would learn how to play fluently using this program.
We keep our lessons short so that he stays interested and when we aren't having a lesson he spends his time creating his own music
It will be a slow progress for us do to our schedule, but I have already seen results with my little one and so I know it will only get better with time
Just my two cents, hope this helps
Take Care and Happy Teaching!!!
