In this crash course we'll talk about what almost every single good singer does in terms of technique. I discuss the elements that you'll see over and over again, ranging from how they use mouth to their attitude.

Young Michael Jackson, Whitney Houston, Neil Patrick Harris, Ariane Grande: they for sure know how to drop the jaw. Let's see how they do it.

Frank Sinatra, Mariah Carey, Christina Aguilera, Ed Sheeran: watch how they put up different versions of what I call a 'badass face'.

Your instrument is your entire body. Watch these singers rocking theirs: Elvis Presley, Aretha Franklin, Beyonce Knowles and Dimash Kudaibergen.

The best performers know that good singing is based on the speaking voice. The extreme version of that voice is the squeaky voice aka 'the twang'. See how these four singers play around with it: Stevie Wonder, Amy Winehouse, Adele, and Justin Bieber.

Going all the way, giving everything, is what sets a professional apart from an amateur. I react to Freddie Mercury, Celine Dion, Adam Lambert and Joe Calderone.

Let's upgrade this question to: have you tried? Have you actually done all of those proven-to-work elements and took them to the extreme?
