I can't remember the exercise, but I remember an exercise involving my

If it was in perfect tune, it sound an audible overtone that was as
strong as the two notes we were playing.

They're called 'difference tones'. They are thoroughly discussed in
Benade's larger book "Fundamentals of Musical Acoustics". They occur,
sometimes less obviously, in 'every day' musical situations.
