I have always liked film music, especially since I investigated composers.
Hans Zimmer, my favorite composer, films in which his compositions were in and I fell in love with each film. (Interstellar, Origin, Davinci Code, gladiator etc...).
How did I manage to do it?
I used the Fl Studio program for it, I searched for tutorials to learn how to use the program and I made songs of all kinds of music. Once I felt that I mastered the program, I decided to throw myself into creating something cinematographic and this is one of the results that I achieved without having any idea of music or musical composition.
The truth is that I am very proud of the result and as time goes by I know that I can improve much more in all my fields.
