1. Don't chant out loud. Wastes breath and distracts you.
2. Know how auto-suggestion / suggestion works.
3. Know the intent of your chanting.
4. Make it automatic, make it so that it starts playing in your mind as if it were a separate audiotrack that keeps playing even if you think other things. No effort repetitive automatic chanting.
5. Enjoy your trance.
For any people really knowledgeable in this matter someone please tell me if you know of any unique qualities to sound combinations such as in Qabalah or in various mantras that could make them special.
Otherwise I think it's just a matter of choosing some words that most strongly capture the intent of what you want to invoke.
…but maybe there is more to it?
