One of the main reasons songwriters get stuck in a creative rut is an overused songwriting process. If you find that you’re always approaching songwriting the same old way and using the same structural design and chords over and over again, just changing how you approach writing can quickly break you out of a creative block. You are not alone for feeling like this. It is a very normal thing among professional songwriters and same as any other problem, there are solutions for it.
Most people think of songwriting process as something that would take weeks or even months. Sometimes, yes, the whole production process (including arrangement, recording and mixing) might take a long time but in fact, the songwriting itself is usually a quick process, simply because a song is the emotions, feelings and expressions of the writer about a specific topic in a specific period of time, right? So, all these feelings and expressions should be translated into a song before they are all gone! Then later the artist can go back to it and “polish” them and prepare them for a proper production!
