The pianist has 85 to 88 keys while the violinist only 4 strings. And yet, by pressing the strings in particular spots, a variety of tones are produced. There is nothing accidental about any of those points – they are the result of years of research and quests of musical aesthetics. But why them? Musicians – both practitioners and theoreticians, mathematicians and other researchers all agree that this was all down to Greek philosopher and scientist Pythagoras. Mathematician Dr. Georgi Dimkov from the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences will convince you there’s a lot more common between music and maths than meets the ear.
