Yes Monika! Totally agree with physical warm-ups as well as vocal.
One thing that I’ve found works really well with my students is setting them the challenge of performing in front of a family member/house mate at home. Even if it’s through the door! By eliminating the idea of “oooh, what if someones listening, what if someones judging, what if what if what if” and actually performing with the attitude of “I can” gets rid of any of their nerves about singing or even just being loud in someone else’s company. They can perform warm-ups or songs as long as someone other than me (the teacher) hears/sees/knows that they are learning to sing.
I hope that makes sense.
