Learn your lyrics. Taking a lyric sheet into the recording booth is impractical as the paper will rustle when moved, interrupting the recording. If you must take in a visual aid, use a dry-erase board and prop it against the wall.
Warm up. Start by taking a few deep breaths and holding them in for around seconds. Then play "motorcycle" by pursing your lips and blowing. This draws blood toward your mouth. Then open and close your mouth repeatedly to warm up your jaw muscles. Yawn a few times, if you can. Yawning draws extra oxygen to the back of your throat.
Remove your shoes, jewellery, noisy clothing and turn off your cell phone. If you're a foot-tapper, the sound of your shoe on the floor can ruin an otherwise perfect take.
Adjust the microphone stand so the microphone is a half-inch below your mouth. Use your singing stance of feet shoulder-width apart, chest out and chin up when setting the height. This way you don't have to stoop to reach the mic, and you can fully project your voice.
Complete a brief soundcheck. Put on your headphones and listen to the backing track. Tell the engineer which tracks to bring down and which tracks to boost. For example, if the bass is too loud and the drums are too quiet, tell them clearly and politely. A poor mix limits your ability to hear your own voice, reducing your chances of nailing the perfect take.
Deliver your first take. Project your voice from the abdomen and regulate your breathing so you exhale when singing. Pull your head away from the microphone at loud parts so you don't "boom." Direct your voice just over the top of, rather than into, the microphone.
Listen to your next instructions. You may be asked to hold off, go harder or repeat certain parts. Stay focused at this stage so you understand what the producer requires.
