Music

I want the sound track for my thriller opening to be a solo piano to create a sense of being abandoned and also a sense of loneliness which convey my characters feelings.
I want the to piano solo to be slow and haunting, I will create this effect by using notes that are off key and having high and sharp notes at tense moments, for example, when my character heres a noise coming from the living room and when my character sees the phone on the chair upside down. I hope this will increase the tension of the audience as well as their fear.
