1903: The composer Leoš Janáček maintained that the melody and rhythms of simple sounds and everyday conversation provided a window on the inner self. Janáček called this concept speech melody, and applied it to robins’ song in a park, to the muttering of an old woman gathering fire wood on a river bank, even to the words of his daughter, Olga, delirious with rheumatic heart disease.
“I don’t want to die; I want to live!” she sobbed. “Such fear!” And a final sigh, “Ah-h,” which Janáček notated as two Ds, a quaver and a crochet, at the bottom of a treble clef, followed by a pause.
