1. Exude confidence. If you don't feel confident, fake it.
2. Arrange a song by a male artist. Arrange a song that isn't Top 40. Or do a jazz standard with a hip-hop groove, or a punk song as a ballad, or a folk song as drum 'n bass. Or better yet, write your own song.
3. Omit syllables from your arrangement and explore what your voice can do without a strict “doh," “bop” or “jin.” Experiment with your instrument!
4. Explore using close, tight, dissonant harmonies instead of very spread voicings where your sopranos are screeching in the stratosphere and “basses” are barely making sound on their lowest notes.
5. Don't be afraid to look and sound ugly. Some of the best stuff will come out when you take risks and aren't worried about what you look or sound like.
6. Take up space! With your voice, your body and overall presence.
7. Arrange for the strengths of your singers. This means it may take longer to build repertoire, but arrangement can be everything!
8. Learn from the male groups, but don't necessarily imitate. Do it YOUR way.
9. The music should be enough to sell your group. Yes to staging, yes to looking sharp, yes to “bringing it” and delivering the song. But in the end, the SONG itself needs to be killer.
10. STOP PLAYING IT SAFE. Just don't do it anymore.
