The evolution of Western pop music over fifty years – from 1960 to 2010 – has been analysed by scientists. A team from Queen Mary University, London and Imperial College looked at more than 17,000 songs from the major American chart, the U.S. Billboard Hot 100. They found three music revolutions – in 1964, 1983 and 1991 – and traced the loss of blues chords from the charts, as well as the birth of disco. The team also refutes claims that pop music is starting to sound the same. Dr Matthias Mauch is from Queen Mary University of London and co-led the research.
