My father loved music, as I mentioned yesterday. He instilled this in my younger brother Dave, and me. Dave plays piano for a living. These days, he is getting back to his roots, playing for himself. Practicing, practicing, practicing.
The study below originated as a pen and ink study. I have a pen nib that is very wide and I love the marks it makes. I made some dotted lines below a wavy form. The form reminded me of a hand. From there I made the leap and added verticals to my dotted line, with the spacing of the black keys on a piano.
