First appearance of this pioneer-paper which helped establishing the foundation of the acoustic theory of this group of musical instruments which depends on coupling of the tongue and the air cavity in the instruments. One of the subjects treated was the use of this coupling to maintain constancy of pitch of a pipe under different intensities of blowing, and the possibility that this might provide an improved standard of pitch.
