I hate preparing lessons for a substitute teacher. Thankfully, the flipped classroom model redefines the work of a sub and allows a teacher to record themselves for their class even when they are gone. The following video was recorded live in class, Thursday, Nov. 6, 2014 using QuickTime's screen recording feature to demonstrate how to enter MIDI notes into GarageBand '11 for the hymn Glory Be To Jesus. Students should watch this video and start making soprano, alto, tenor, and bass tracks their own project. If you have questions, please comment to this blog article or to the YouTube video itself.
