Songwriters, no inspiration? Here are 4 tips to get you started :)

Intro:

In all creative processes, there's a part that comes from somewhere that is not from out conscious perception - call it talent. It is therefore mandatory to first be aware of it and to catch it when it comes. Journaling is a very good way to let the creativity flow. You can be talking to someone or watching a movie and then something comes up, out of nowhere. Stop and pick it up. A bit of a chorus, a bassline, a fragment of melody, catchy lyrics... it can be anything, a ambiance... stay aware of what comes into your mind. The best ideas come that way. If you don't pick it up, you will forget it so find a way to keep track (notepad, audio recorder... whatever)

When you are stuck and you need absolutely to write a song NOW for a project, here are a few ideas to help you start.

(I'm assuming you are able to accompany yourself a minimum on an instrument.)

Pick a series of chords from a song you know, and see what you can do with it. Play them in different ways tempos, change the order... it should guide you somewhere.
Are you practicing an instrument? You are working on a new exercise? Use it to start your song.
Find a poem or writing (copyright free is best) - say the text out loud and see if the music of the words put together can inspire you a melody, a rhythm or something to start from.
Record yourself playing something without thinking about it, listen to it and ideas will pop out..
