First, make your Soundcloud account

Second, follow LUC University Chorus on Soundcloud  

Third, listen and learn your voice part, then record along to your voice part (You will need to have your Soundcloud account open in a different window in order to listen to the midi files in the LUC Soundcloud account.)
How to record: http://help.soundcloud.com/customer/portal/articles/1207834

Fourth, title your track as follows: Name of piece, your name, your voice part
Under settings for your track, set it to private, and share it with LUC University Chorus.  

Last, the all important SAVE button at the bottom of the page. The SAVE at the bottom of the page is not easy to see if you do not scroll down, and we don't want your work to be lost!

Here is a how-to video on the whole process!
