My teaching methods are listening to the student sing, give my constructive feedback, guide them on how to try and sing the song or how i feel like it would sound with a different approach and then record their vocals over a backing track of their choice for their own personal development.

I use youtube videos for the backing tracks and warm ups as it’s easy access for the student also.
The warm ups are your standard scales while also getting your body ready to sing with some stretching.
