What methods do people use to write songs?
It varies between individuals. Some people set aside a particular time of day to write, while others wait for the muse to strike them. Some people pick particular topics to write about, while others play around with words and sounds to form ideas. Some people work on one song at a time until it’s finished, while others work on several at a time. Many songs are written while practicing, jamming, etc., where even a mistake can be the seed for a great idea. Try experimenting with several methods and use the ones you feel most comfortable with.
