As a banking professional, I had a rather tight schedule and was fairly clueless on music fundas.
At NSM, not only did the schedule fit in conveniently, the syllabus was quite well planned and gave me a good grounding on keybord basics and theory.
While I have a lot more distance to travel before I qualify as a good keyboardist, it was a fun experience. As a banker I have to say this: this was worth the buck! Go for it!!
