Here is a situation where mindfulness techniques can be incorporated into a lesson. Help the student learn how to relax, release anxiety, draw into the present moment. Suggest vocal as well as physical exercises that can be helpful anytime or anyplace.

One thing I have found helpful is to do fifteen minutes of breathing exercises every single time I practice, sing, perform or train my voice whether in a choir, with nobody, before a performance or with a vocal teacher. It helps ease the tension inside from life's stresses and it also warms up the muscles needed to sing well. It also is handy to visualise something low to the ground, when singing high, so as to counteract any nerves about hitting the pitch with extreme accuracy. Likewise, try an action such as raising your hand in solfege movements to accurately pinpoint the correct melody pattern. ( Teacher training recommended, courses exist I believe ). Also, you must must be confident and self assured & most importantly believe in you!
