If you are doing a video submission, you will need a few things: a device to play music from (such as a computer, tablet or an iPod), and a device to record the video (probably your smart phone).
Use the playback device to play the chorus, bridge, and tag of He's Able by Deitrick Haddon.
First, record yourself singing along in whichever part you're auditioning for - Sopranos sing soprano line, altos sing alto line, and tenors sing tenor.
Next, record a song of your choosing done a capella. No music, just you singing to the camera.
Once complete, upload your files to this Dropbox Link.
