Watch, listen, and learn as pianist and composer Nahre Sol plays what you might think of as a very simple song, Happy Birthday, in 16 increasing levels of complexity. She starts out using a single finger and ends by playing an original composition that seemingly requires 12 or 13 fingers to play. This gave me, a musical dunce, a tiny glimpse into what a composer does.
Sol has a popular YouTube channel where she posts videos of her musical explorations, including Improvising in the Style of Different Classical Composers and The Blues, As Digested by a Classical Musician. (via open culture)
