1. Relax your throat. Your vocal cords should be loose and relaxed before you start screaming, so that you only vibrate your vocal cords, instead of straining your entire throat.
2. Take a deep breath. Use your diaphragm to push the air out of your lungs slowly and consistently, so that your scream has a low, guttural quality.
3. Open your mouth wide and stretch your tongue. This will help to create more space in your throat, which will allow your vocal cords to vibrate more freely.
4. Start by making a high-pitched, "ahh" sound. As you do this, gradually lower your pitch until you reach a low, guttural scream. Experiment with different pitches and vocal techniques until you find the sound that you are looking for.
5. Practice. The more you practice black metal screaming, the easier it will become. Start by practicing for a few minutes each day, and gradually increase the amount of time that you spend screaming as you get more comfortable with the technique.
Here are some additional tips for black metal screaming:
- Use a microphone that is positioned close to your mouth, so that it can pick up the low frequencies of your scream.
- Experiment with different recording techniques, such as using a compressor to add sustain to your scream.
- Use a mix of both clean and distorted vocals to create a more interesting sound.
- Don't be afraid to experiment with different screaming techniques and styles. The most important thing is to find a sound that you are happy with.
