Luna's Little Organ Book is a collection of twenty-six short organ pieces that have been minimally adapted to be playable on one manual without pedal. All pieces are within a 54-note compass of C to f''', ranging in difficulty from sight-readable to challenging. They are suitable for any size organ but are primarily intended to supplement the idiomatic repertoire of small chapel and home practice organs. This book is a collaboration of composers David Paul Werner and Chi Ying Lam. The music is printed on high-opacity 70# (103gsm) paper.
