Nearly one month from purchasing Program, I completed lots of pieces such as Introductory songs, Nursery songs and 2 songs from Nursery Primer. I will tell you the way I have done with the program.
First, I play all games. I finish 2 games: Treble Staff and Bass Staff. The game I like most is the Note Duration because I can hear music when I learn notes. The game I feel difficult is the Note Alphabet because I don't make the right notes in the correct blank.
Second, I play the Introductory songs then the Nursery Songs. One in one, I have learned one song in a day. Besides that, I practice 4 fingers exercise that download in Instructional videos. At the moment, I play a new piece I read music using P5, P6 (in Gentle piano)
I play piano when I have free time and when my son go to bed.
These all the steps I have done with softmozart, especially I fell my left hand from hard to soft when I play piano.

I share my feelings and my progress when playing piano without piano teachers. Could you - other mums and adults- tell your progress how good you are and the matters you deal with?
Hellene, Could you tell me that my progress that I made is slow or fast?
