This is a miniature score (with commentary) of Yasushi Akutagawa's "Three Symphonic Chapters" (Trinità Sinfonica). This work was composed in 1948 and premiered in 1949 with the composer conducting the Tokyo Philharmonic Orchestra. It consists of three movements, consisting of "Capriccio", "Ninnerella (Lullaby)", and "Finale", and is now regarded as one of Akutagawa's career works. This book has been newly revised and reprinted from the first edition published in December 1992.
