I transcribed and played "berceuse"(meaning lullaby in French), a track from the CD "Shiro SAGISU Music from 'SHIN EVANGELION '", which is a collection of songs used in the movie of Shin Evangelion.
It's the music that was played in a scene where Rei Ayanami's look-alike comforted Touji and the class president's baby.
Musically, I thought this piece has an obscure tonality combined with the melody which has a wavering mood, was kind of like expressing the image of your head when you are half-asleep, and this music might help you fall asleep. Please enjoy.
