	Train to Okinawa	尺八 : 皇保
After many hours of playing sparse, meditative music together, it was time for something 'rich, romantic and cello-like'. Half an hour later, Peter had composed a theme which, with an improvised part on the shakuhachi floating above it, forms the opening and closing sections of this piece. The middle section, based loosely on the theme, is an entirely improvised duet variation, reminiscent of European baroque counterpoint.
