Rehearsal for vocal performance can accomplish little- or can prepare you for the vocal event you want to have next time your voice hits the stage. Here are the two ways you need to practice...
- Technically: learning the melody, lyrics, rhythms and structure of the song while practicing with perfect form; working out trouble spots to find vocal techniques that fix the issues; working up vocal stamina.
- Psychologically: practicing 'performance state'; focusing your mind and your body language into communication mode which authentically delivers the message in the song TO someone specific for the benefit of a listening audience.
Practice technically first. Practice psychologically focused 'performance state' less often... purposefully and separately from technical practice. It's hard to drum up the moment, or 'zone', too many times in a row.
Create muscle memory that moves:
Practicing technically of course creates muscle memory. Then psychologically practicing the act of communicating your song TO someone infuses and purposes the muscle memory with feeling and emotion that can elicit emotional response from your audience when you go onstage. Then sing your butt off and Make Somebody Feel Something!
