ALWAYS RHYME YOUR LYRICS
A good way to learn to write lyrics is to "borrow" from other songs. For example take a song you really like and mimic the rhyme scheme and meter. When I say meter I mean syllables per word. Thinking in terms of nouns and verbs really helps in rewriting the borrowed lyric. The use of adverbs never really works in lyrical writings. For example "She was 'swiftly' running" swiftly being the adverb modifying the verb. Adjectives and all the other parts of speech are great at painting a picture so use them freely. Once the lyrics are starting to come together begin making your own chord progressions, or if you can't come up with a chord progression borrow one of those too. I must say it's best not to borrow the chord progression and the lyric scheme from the same song because that starts sounding too much like a pastiche. If you change the drums and rhythm up enough when borrowing both the chords and lyrics, that may be enough to create something totally fresh and new, but be cautious. When facing writers block borrowing a line here or there from a well written poem might get you out of a rut. Below is a rough example. The song was picked randomly from one of billboard's top new albums lists. The lyrics I wrote under Prince's are a bit goofy, but I wrote them fast and didn't focus on meter as much as you probably should. If you just let go and don't worry too much about the taboo of "borrowing" great songs are in your future. Throughout history all the famous composers borrowed. It was not until the late 1900's that "borrowing" is sometimes thought of synonymously with plagiarism. All the music you like would have never been written if the writers had this concern. So, loosen up, have fun, and remember that music like art is never finished only abandoned.
