My son (five years old) recently started practicing playing very softly. I believe that I have read here at TM that this is a good way to build your playing ability?? He is amazing me the way he is controlling his volume, however, when he is playing quietly, most of the notes sound very airy unlike when he plays at a normal volume and sounds good. He thinks it is quite hysterical to go from super quiet to wake up the neighborhood loud just to be sure he is the center of attention, the little stinker! At this point, I am keeping a pretty hands off approach and just letting him play and have fun. He continues to be self-motivated and improving. But I also don't want to foster bad habits by being too laid back. Is the airy tone something that will likely work itself out?
