Ironically, Hall admitted nerves got the better of her before talking to the teenagers, but in front of the classroom she acted like a natural-born teacher.
"I get really apprehensive to start with because I am like, 'oh I hope I can give them some tools to go away with'. And they will be like, 'I remember when she said that'. It's constantly on my mind passing on some gems."
Hall was passionate about working with youth and said there was so much talent laying under the surface.
"It's like kind of sitting under the radar and I know they have got heaps in them, it's just getting it out. They don't need to be scared. Lots of things can be said through music - both direct and indirect."
Head of music, teacher Katrina Wickham said Hall was an inspiration and was accepting of any differences.
"There is no wrong way or right way and she has challenged pupils that were only instrumentalists to extend themselves and write lyrics. She is fabulous."
The students had seen her on YouTube and listened to her tracks online.
It was a great opportunity for the students to meet a Sony-signed recording artist, she said.
"This is the first year we have had a mentor in the school."
But it would definitely be applying for the opportunity again, she said.
