Erik Satie's music comes from solitude and touches us deeply. "It is my heart that swings," he says in his commentary on "Balançoire," while the pianist's left hand hops back and forth over the right. This is musically articulated with precision yet remains open in its meaning. Pianist and music writer Tomas Bächli explains Satie's music at the piano: To allow listeners to hear what is being discussed, there is a web version of the book with audio and video files. However, Bächli also examines the legendary Erik Satie from other perspectives - as a participant in film productions, as a visual artist, and as a hoarder.
