Hello Peter,

This piece definitely invokes English pastoral imagery.

The brief excursion into mixed tonality in the middle section felt isolated to me rather than integrated. However, such a composition device is certainly legitimate. (I particularly enjoy hearing the opposite in pieces that have complex tonality and then briefly make an excursion in simple tonality.) In this brief dischordant portion of the piece, you've reminded your daughter that she's heard stranger 12-tone compositions sounding through the walls of your study.

Cheers
-- Mark
