New technology can identify the Baroque, Classical and Romantic periods after 'hearing' only three notes.

Pablo Rodriguez Zivic from the University of Buenos Aires and Favio Shifres from the University of La Plata have invented Peachnote, a machine that can identify a musical era and composer after listening to only three notes by discovering patterns across songs.

The inventors believe that this technology could also identify other patterns in speech through recorded phone interviews and may lead to an earlier diagnosis for those with Parkinson’s as the disease affects vocal chords early on. The technology can be used to identify the combination of sounds to make early diagnosis.
