Audio of a 1994 vocal training session between Michael Jackson and legendary vocal coach Seth Riggs has floated around YouTube for years. Here is the exercise list for this session. Each exercise has a link to the audio on YouTube so you can hear it demonstrated by the King of Pop himself. These exercises are the epitome of advanced Speech-Level Singing practice. Most people will need to work their way up to this, so be sure to limit the range and tempo to what you're comfortable. It's crazy they jam this entire list of 25 exercises into 25 minutes of practice. That's a bit short for me so I set each exercise to 2 minutes. You can get through this in under an hour.
