One guy even wants to know how well he got it down. Then you need to get a song playing over and over again while you're writing a piece. Your fingers should to travel over the keyboard to the beat of the music. Your shoulders should rock from side to side as you type the text. Get a good song going and the piece just writes itself.
Every beat is a key.
Every pause finishes a sentence. Sometimes it's a challenge to make the words match the flow of the music. A good keyboard helps. It's a sentimental song about lost love. The Mississippi River starts as a stream in Minnesota that you can walk across in five steps.
