Shigeki....Bravo!!
I applaud you for your exploration into so many types of musical composition. I love how you took your interest in a literary novel and brought it to life in operatic form. The structure of the song is very much in the operatic tradition for Arias, the melody is lovely and the piano accompaniment with light strings is just right. Now all you have to do is complete the libretto and compose the rest of the opera!
