The word song is often used to describe any kind of music that is sung. This can be anything from Irish folk songs, African storytelling songs, Christian hymns or even heavy metal music. However if we want to be precise about it, a song is actually a musical composition that combines lyrics with a specific musical structure that is usually based around verses and choruses.
Songwriters tend to be very precious about the work they produce, especially in the ideas and draft stages. This can lead them to avoid changes that the song would benefit from because they have become attached to a particular melody or line of lyrics. This is a real problem because the songwriter will have no way to know whether a change will improve the song if they only have an idea of what it might sound like.
The best advice that anyone can give to a songwriter is to learn how to listen objectively to the music they produce and the way they use the different parts of a song. They should also develop a process for writing their songs that is repeatable and will increase the number of songs they can create and finish, as well as improving their overall standard. Having no method or working in an unpredictable manner can lead to inconsistent results with a high percentage of unfinished and unsuccessful songs. Learning how to develop a process that will consistently improve your songs and make them more fit for purpose can help you write more songs, that you are proud to represent your music with.
