Piano Solo - Level 4 - Digital Download SKU: A0.1015884 Composed by Sébastien MONNERET. 20th Century,Contemporary. Score. 7 pages. Sebastien MONNERET #5001745. Published by Sebastien MONNERET (A0.1015884). Nocturnia No. 1, Walking On The Blue Side is an illustration of the fragile border that exists between happiness and melancholy. It is the simple idea that one can, at any moment, suddenly pass from nothing to anything, without being able to do anything. The word Walking refers to the left-handed mode of play called Walking Bass often used in jazz piano that I used. It's finally a nod to Pink Floyd's album Dark Side of the Moon and Miles Davis' album Kind of Blue.
