From Sixty Short Pieces for Pipe or Reed Organ.
They are described as being a collection of easy pieces - they can be played on manuals or with pedals.
Flor Peeters (1903 - 1986) was a Belgian organist, composer and teacher. To read more about him visit http://www.bach-cantatas.com/Lib/Peeters-Flor.htm
Played on the rear ranks.
Really struggled with this one for a while I guess lydian isn't something we play in often and some of the stretches were a bit awkward for me.
Hope you enjoy
