Extra Video Example of Ventricular Fold use in harmonic singing

Here are two extra videos in case you are interested in hearing some different styles of harmonic singing.

Listen for the lowest notes in this example. They are accomplished by using the ventricular folds to lower the pitch. Additionally, notice that this singer sings a melody rather than a drone. But he uses upper harmonics on top of the melody and occasionally changes them when holding notes for longer periods.
