for my music pieces i am going to use is called Elizabeth it is from the bioshock series as it is full of emotion and sadness
in this piece the use of the violins is rather intuitive as they tend to use it to stimulate the feeling of wrong doing as it makes you think that you did something wrong and it is eating you inside and that is is cemented by the piano and the organ that are playing in the background of the violins.
layering voice over on top of music is a rather hard task. you have to create a different channel on adobe audition and be able to adjust the volume of it and the intensity of it to make it audible.
