I wrote "PolyKeys" this morning (10/30/05). It is not in honor of some parrot. It features two insertions of the GPO harpsichord in one version and two instances of the GPO Steinway piano in the other.
This work contains six key changes. Near the end, transitioning from G minor back to the original key of A minor is not easy and in this case, I didn't do it very smoothly. Sorry 'bout that.
Regards to all,
