Influence and effect of Sound/ or Music in Film opening's

The music while " I remember that it hurt" comes up on the screen you can hear the typing really faintly of this as it appears on the screen.

Again the typewriting is heard as it is typing above his dialogue as he is saying exactly what comes up on the screen.

The music which is playing as the scene opens with the dialogue is just a piano and a guitar over the top. I think this is effective because when he starts speaking the music is also reduced slightly into the background. Therefore if we were to use any music i would make sure to lower the music ( fade) slightly when there is any form of dialogue. I also think that the music is important as it is effective in a way which we sympathise for the girl and know already that the boy adores this girl by the way he is looking at her and with what is saying above the filming. What the boy is saying over the filming is in his mind and not literally out loud as he is looking at the girl.
