Pianoforte and Mozart's keyboard music

I think the invention of the pianoforte has contributed to popularization of the music. Clavichord and Chembalo were the most popular keyboard instruments before 1709, but the Clavichord and Chembalo had limited tones. Thus, these were played for chamber music. However, Pianoforte makes a big and strong sound because it develops sound through the hammer that hits the strings. Pianoforte could be played in concert or ensemble (in large place) so that many people could hear the music.

First of all, I would like to know how Mozart could get a good music education from their father as a mom....
In my opinion, the Mozart's keyboard music shows difference of dynamic and brilliant sound. Pianoforte could make Mozart's keyboard music more effectively and dramatically because Pianoforte could express the intention of Mozart such as remarkable dynamic or brilliant and deep sound. Mozart might know well the characteristics of Pianoforte so he could compose beautiful keyboard pieces.
