The hills are alive with the science of music

Every month The Science Museum puts on a late night special where grown-ups can play unashamedly with the attractions without having to shoulder barge a toddler out of the way.

We went to two lectures, one on music's effect on the brain and a second by Robin Wilson on the intervals between notes and their mathematical properties. It was fascinating to learn how the system of equal temperament (used to correct the gaps between musical intervals) means that every major third on a piano is sharp, but we are accustomed to hearing it.

Unfortunately, my own temperament was far from being equal and we made for the relative solace of the tube. If you like the idea of having a beer as you stroll around the museum, pop along.
