I always like this Vocaliod opera song: https://www.youtube.com/watch?v=VseHlKR4Ew8 (Voi che Sapete)

While the song is playing you can see the settings. I've played with it once but it's hard to get it right.

First you place the notes to add pitch and length. Then you attach phonetic codes to the notes. So it's not like you are adding words to notes. It's all about how it should sound. Then you also can add things like amplitude settings.
