One was majoring in choir conducting and another is also taking composition lessons from my colleague at school.
So it seems very reasonable to suggest to you, my dear readers too that you take an organ music collection that you love (either by one composer or by several) and play at least one piece a day in a very slow tempo one time through.
The results will start to be apparent after you sight-read a few such collections - probably in 6-9 months from now.
It's difficult to overestimate the value of such endeavor. If you haven't done it before, it will likely be the biggest gift you have given yourself in organ playing in years, the one which will make or break the success of reaching your dream.
