Others more qualified than I have been posting some of Vierne's works lately. I thought it was time to get in on the act and go to something 'simpler' than Dupre! I tell you, it is amazing how spending time working on harder/complex pieces helps you crack what you were stuck on a couple of weeks ago. My finger substitution has become almost fluid now rather than fumbling about with the grace of an elephant in a ballet.
This work comes from Vierne's 24 pieces en style libre. The scores can be found here: http://imslp.org/wiki/24_Pièces_en_style_libre,_Op.31_(Vierne,_Louis
The registration calls for
G. O. : Fonds doux 8', Nasard
Récit : Flûtes 8' et 4'
Péd. : Bourdon 16' et 8'
Tirasse du G. O.
I have matched this as closely as possible. The Great used Second Diapason, Harmonic Flute and Twelfth. The other two manuals provided the Flutes.
Hope you enjoy!
