University of Melbourne Applications

My explorations of possibly studying music therapy came to a roadblock recently. By chance my colleague found a newspaper advert publicizing the auditions held by the Uni of Melbourne professor for music degree applicants, which led me to renew my explorations in embarking on this course of study/work.
I surfed online and realised that Melbourne offered a graduate diploma in music, and I thought to myself that perhaps I could do a grad-dip before applying to do a full Masters in music therapy. I emailed my idea to an Australian music therapist based in Singapore whom I had previously corresponded with, and she put me in touch with none other than a music therapist lecturer in Uni of Melbourne!
Through this lecturer I got to know that my current undergrad degree actually qualifies me to apply directly for the masters program. This cheered me on and knowing that I could apply with a fee waiver through OAL made me think even more seriously about actually doing it.
BUT, after corresponding with the lecturer some more to clarify some details, I came to a realisation that some of the application requirements for the course were quite daunting. Amongst these include:
1) Getting an academic reference AND one from a person who can attest to my musical ability. The latter I could get from my music teacher. But the former, I think my professors back in Cal would be hard pressed to even remember my name, nevermind write me a good recommendation.
2) The vocal part of the audition requires me to sing and play accompaniment on the guitar at the same time. Now sing and play the piano I can. The guitar, I don't know HOW to play one. And apparently it is an important part of the profession!
So, BIG roadblock. To do music therapy I have to learn the guitar. How easy is that??
