Music is a product of creativity of a person and if the person who created the music is not able to produce it with instruments in a studio, he gets into great difficulties. You have to rely completely on another producer to give shape to your music. You have to spend a lot for that. And even after the production of music, the person who produced your music may demand a royalty from you. Many copyright issues arise from this problem. Even if you know the way of playing the instruments and recording the music, the process is very expensive.
