A wish list for neuroscientists from a musician
From the safe distance of a composer with an armchair appreciation for science, I'm something of a fan of the neuroscience of music. It's really exciting stuff and my impression is that we're only beginning to learn about it. Here are some aspects of music that I'd like — as a composer — neuroscience to tell us more about; as music if the temporal art par excellence, it's not surprising that they have everything to do with how we process events in time: 1. The two irreversible arrows of music: in pitch and in time. Inverting a sequence of pitches creates only a weak equivalence, indeed an equivalence which deteriorates as one moves towards extremes. And in time, a reversal of a sequence, last-on-first-out, is also only weakly equivalent. 2. The perceptual "borderlands" between parameters: between pitch and timbre or between form and rhythm or rhythm and pitch, including such phenomena as interference beating*. 3. The "chunking" of musical m...
