Row Your Boat Multi-Track
This idea was taken from the amazing Middle School Music Technology class content in MusicFirst. I recommend checking out their subscription options if you like this idea. MusicFirst combines the activity with curated YouTube and Spotify playlists that give students an idea about early recording studio practices for multi-track recording before music was produced digitally.
I am giving an overview of this project with permission from MusicFirst. Full Disclosure: MusicFirst is a past sponsor of the Music Ed Tech Talk blog and podcast.
To start, the student performs the song Row Row Row Your Boat into a software instrument track in Soundtrap. After it is recorded, they quantize it to the nearest 1/8th or 1/16th note so that it is rhythmically accurate.
Next, they duplicate this track two times. Using the piano roll to edit the MIDI content of each loop, students select all notes and drag them higher to create harmony. I have them move the second track a third higher and the next track a fifth higher so that they get a nice three-part voicing.
