With Quicktime Player Screen Recording mode, Garage Band, Google Slide (lesson powerpoint) and Spotify, I created a playlist of Virtual Drum Lessons for my Secondary class.
Kids were quite impressed especially when they get to play along simple drum beats with pop songs.
There are 10 videos in the playlist including the a quick setup video at the beginning. You may skip to the last two videos to hear some surprise pop music.
This videos are not perfectly made they give a strong idea of how you can teach music tech in class for lack of real instruments.
