Simple melodies and tunes can be taken to whole new heights by adding layers of complex harmonies and leaps yet still maintain the original melody which can only make you amazed at the outcome. Even something as simple as the "Happy Birthday" song can become a beautifully complicated concerto in the right hands.
Pianist and composer Nahre Sol attempts to play “Happy Birthday” in 16 levels of complexity. Nahre starts playing the iconic tune with just one finger and adds more and more layers until she’s playing it with extended harmonies, elongated melodies and staggered leaps.
