Rainbow Measures (2012) by Rob Keeley
For Flute Ensemble
2 picc, 4 flutes, 2 alto flutes
When the opportunity to write for Ayre Flutes arose, my initial thrill at writing for the glorious and undeniably exotic combination of eight flutes (actually four flutes, two piccolos and two altos) was accompanied soon after by the need to use this ensemble for more than mere colour, so I thought of a 9-minute fantasy inspired partly by my fascination with the great scientist Sir Isaac Newton and possessed a tin ear: the visual and conceptual for me easliy convert into the musical, and imagining each player as a colour of the rainbow (yes, I know there are actually on seven!) the piece was relatively quickly and enjoyable finished. William blake notoriously took Newton to task (as he saw it) for reducing the mysteries of Nature to mathematical formulae, but for me, scientific laws delineate wonders, and it is after all the composer's prerogative to use whatever he needs to get the notes written.
The result is, I hope, a lively, athletic and colourful full of varied colours, counterpoints and textures.
