Think of ways in which to express your true feelings without resorting to profanity. Though it might be cathartic to express, or to hear expressed, feelings of rage, anarchist revolt or colorful references to carnal activity, you should be aware such forms of expression may be considered illustrations of a small and unimaginative vocabulary.
Read your thesaurus of choice to find alternative words that are not insulting, offensive or likely to frighten someone. For instance, if your song is about asking someone to leave and never return, use words suggesting this politely and with respect even if you are deeply hurt, angry and upset.
Take time to work though all your lyrics deleting words that might lose you fans and audiences. Substitute words suggesting a gentler, more controlled you. Ensure the words scan otherwise you will lose the meter and rhythm of your song lines and you will have awkward pauses during your performances.
Learn the curse words in other languages and be aware of the language taboos in a range of countries so you do not inadvertently introduce them into your lyrics. Compare the curse words used in Britain with those used in the United States, for example, and avoid using any of them.
Play your entire music collection in the privacy of your own house before accepting any further bookings or broadcasting any further shows. Make detailed notes for each CD, tape or record of any curse words you encounter, noting the exact timing on the track when each occurs.
Write a playlist and highlight those songs containing curse words. At your gig or in your studio, keep a close eye on the timings and fade the music down at precisely the moment when the curse words are about to be sung. Turn the volume back up again when the danger has passed. You might like to say something encouraging into the microphone at such points to keep your audience engaged.
Cut the songs completely from your repertoire if you find the timings difficult to monitor. If and when these songs are requested, or your producer orders you to include them, suggest alternatives. Explain why you have restricted the airtime for these songs. Be prepared to cite academic research showing the long-term damaging effect of cursing and swearing and the inevitable decline in social standards, as well as pointing out the rulings of the FCC.
