For my soundtrack I have used my guitar to create a few recording that i have been using in garage band to loop the sequence easier but for the actually eddying of the tracks i have been using Adobe Sound booth. At home i am play with a violin to get the type of sound that i need to use in the opening scene.
During the process of editing i have also colour corrected the clips so the look more natural and not so yellow as i did not white balance properlly when filming, and the lights I used were slightly yellow and not completely white.
