I love to use the Acapella app to help create Orff arrangements. You can record videos and hear multiple parts simultaneously. There is a free version and paid version available in the Apple Store and Google Play.
With the free version of the app, you can record up to one minute in length. Since most of the Orff arrangements use repeated ostinatos, I have never needed a video longer than one minute. The paid upgrade offers longer videos and more options for formatting the video windows.
I have used the Acapella app to create videos to share Orff arrangements with other teachers. I have also posted videos on my classroom webpage for students to watch and practice at home. A few examples can be found below.
I have recently explored the social features of the app and would love to collaborate with other music teachers. If you download the app, you can click the “Discover” tab at the bottom of the screen and search for song titles, artists, tags, or people. I have added the tag #orff or #recorder to my videos.. If you would like to follow me, search for “mrsdennis” under people. If you follow me, I will follow you back. I look forward to building a community of music educators sharing Orff arrangements with each other!
