Relativity of musical mood

In quite possibly the coolest ever application of the Doppler effect, Kaća Bradonjić has shown what velocity you ought to move in to hear, e.g., a major (triad) chord as a minor chord and vice versa, if the three notes are played from three different locations.  (I shan’t pretend to have waded through the maths.)
