41.2 Hz: the low E string of a bass

41.20 Hz is the open fourth string of a bass guitar and of a double bass in standard tuning — an octave below a guitar’s low E. Many small speakers and headphones barely reproduce it, so a bass can be heard more clearly through its overtones than through this fundamental.
