Q♣ Queen of Clubs in The Rock Songwriter’s Deck: 52 Ways to Write a Song
The Queen of Clubs invites you to take her club and hit people over the head with it. Wham!
In other words, write a song with a powerful, direct, and visceral impact. Don't be subtle in any way. Turn the volume up to eleven. Keep it simple, and make it strong. Spell the key words out if you have to. Sing the title line loudly, then sing it again, and again, and again. The audience should be left with no doubt about your song's message.
If you're afraid you might be overdoing it, that's a sign that you need to dial it up even more — until you're sure you're overdoing it! No doubt some people in your audience will complain that your song is too obvious and too repetitive. But even the complainers will remember your hook and sing it to themselves later, like it or not.
Sometimes you just need to sing loudly and carry a big club.
