1. Rehearse Your Entire Performance
To some this is a no-brainer, but to many, it is ignored and becomes apparent the second they step on stage. Musicians are creative individuals and put an immense amount of energy into creating their music. Though the creation itself might be their prime focus, the live performance of their music deserves an equal amount of attention. When I say rehearse your ENTIRE performance, I mean rehearse everything, down to the seconds in between songs. Obviously you need to rehearse the music, that should go without saying, but the moment you touch that stage, all eyes are on you and that audience will see every single thing you do.
That might mean practicing your set while walking on a treadmill (to help with timing your breathing). It could entail jumping around and acting out every movement in your desired outfit, that way you don’t have a wardrobe malfunction. The more you rehearse and the more you calculate every move, the more you will take away from your live performance. Plus, as you practice little things like what you say in between songs or how you walk on and off the stage, the easier it is for your brain to focus on the real important stuff. Such as, I don’t know, playing your music in front of strangers? Try to understand what type of crowd will be in attendance and run yourself through as many possible scenarios beforehand, that way you are extremely prepared.
