We all have habits. Some good, some bad. When it comes to singing, it’s important to understand what you already do well, versus what you don’t do so well.
In my case, I have a habit of not “yawning” enough. I don’t open the back of my throat very well. I get lazy and forget. I need to remember every time so I develop a new habit every time I sing. I also have a habit of poor posture when singing at the piano. My back isn’t straight, and tend to hunch over.
What are your habits? Which ones are good? Which ones are not so good? What are you focusing on when you sing?
