Here is a cute little video of Mary playing the harmonica, with mommy accompanying her. . .
Mary would play a note and then Kate would copy it, Mary absolutely loved it! We have been working a lot with Mary blowing whistles and playing harmonica to give her little lungs and diaphragm a workout. It is great for increasing her breath support and even her vocal volume.
P.S. and of course she is STILL wearing her Tutu!!
