In 1974, when I was 14 years old, I performed the Mendelssohn Piano Concerto at the Spoke World's Fair with the Granite Youth Symphony. Recently I found the recording of it (51 years ago) and decided to paint a piece as I listened. "Allegro" was born! I used 36 metallic paint colors. My first swoosh was very still and clean--so I decided to take my brush and roll the paint in sync with the music. The black metal representing the black Steinway grand piano I performed on, I love how the "rolls" in the paint look 3 dimensional from different angles. My actual 1" acrylic block image is with natural light, and it can be turned in all 4 directions. Feels like a new piece of art each time!
