Four Steps Towards an Untempered Clavier
for re-tuned electronic keyboard, four hands (1989/2014), c.11’
What if I, like Bach, were to create music in different keys using one of the many unequal temperaments? But rather than using a temperament in which every key was slightly different though still “in tune,” I used a temperament in which every key was completely different and most were actually “out of tune.”
