Helmholtz Subharmonic Series

"Helmholtz, writing about the sympathetic vibrations and speaking of placing a wooden chip on C string of a piano, writes: the motion of the chip is greatest when one of the undertones of C is struck such as C F C A? F D C.

This suggests sounding an undertone with the fundamental frequency will resonate a body physiologically more than an overtone or a partial will." [source unknown]
