The 22-tone equal tempered system is, without a doubt, my favourite tuning system for solo piano music. This piano improvisation was recorded about 6 or 7 years ago. Despite the many mistakes it has a quality that I like. It was recorded in two takes - one take for the chord and melody, then another take to overdub those low, punctuating notes. If I'm ever able to find the original MIDI recording then I would love to render it in higher quality.
