Newlands arranged all of the known elements, starting with hydrogen and ending with thorium (atomic weight 232), into eight groups of seven, which he likened to octaves of music. [ 6 ] [ 7 ] In Newlands' table, the elements were ordered by the atomic weights that were known at the time and were numbered sequentially to show their order.
Newlands published several short letters on classification of elements from 1863 to 1865 and he read a paper on the subject to the Chemical Society in 1866. (This paper was not published, but an account of it was reported in the Chemical News.) He applied the term "Law of octaves" starting in 1865.
The law of octaves relates all processes which occur in time to the diatonic scale, ascribing a particular meaning to the intervals corresponding to the just diatonic semitone (a pitch ratio of 16:15). All vibrations are said to proceed with periodic unevenness corresponding to the diatonic scale.
