Produced by: Physics Girl
Description: Try to sing up the scale of notes into a pipe, and you’ll find certain notes are impossible to sing. WHY?!

The first resonance of the pipe were were using was around 70 Hz, which was lower than any of us could sing. A bass singer could hit that note, but were were singing in the range of the second and third resonances of the pipe.
