I teach from my home studio in Balwyn. Although my background is in classical singing, I teach contemporary as well. It's a different kettle of fish.  I use the recording equipment for both streams. Recording your voice and listening back can be very powerful tool. Every student is different. Some benefit from recording equipment more than others and I'll always take that into consideration. Some people hate the sound of their own voice and some are OK with it. I think it's really important to hear yourself as you are and be comfortable with that. It's also always there if a student needs to make a quick demo. Plus I love twiddling the knobs and I look pretty cool with the head phones on.
