Good luck, Students.
Keep in mind that these files are meant to help in your practice, but do not replace the time you spend preparing with your director. Rehearsal files tend to be somewhat unmusical, ignoring fermatas, and unable to replicate dynamic changes. These files will be great for getting the notes and rhythms, after which you should put them away and begin making expressive music.
