This article is a great resource for any jazz singers on our site who also teach in a community that perhaps leans into the classical voice tradition. In my teaching career here in Orlando at Rollins College and Valencia College I have learned that "talking their talk" has helped me gain traction and respect for jazz singing. I'd love to read other sort of "classical/jazz crossover" article types.

Diana Spradling also has a wonderful jazz voice pedagogy book that we all should own https://www.amazon.com/Jazz-Singing-Developing-Artistry-Authenticity/dp/0980210402
