I’m Dr Anna Mlynek-Kalman (PhD) and I’d like to let your readers know that I provide an on-line course helping teachers create reflective musical process situations in an effort to warm up their own voices. This help prepare them to sing with children and the helps warm their voices and children’s voices, simultaneously. Once teachers understand how to warm their voices through playful interactions with children they should be able to sing many of your songs more confidently, live with children. We find more and more teachers turn to using YouTube recordings as their music program which I would say in many cases becomes mis-education. To avoid this trap and to help teachers sing live with children, as part of my PHD I created a simple, easy to implement, Contour Vocal Play Framework. I have also created a simple 2 hour certified online course found here https://www.musicworksmagic.com/programs/100-organic-intro/
