Law of octaves was established by newland, before mandelleve.
It states that :
The properties of elements will repeat themselves after every 8th element. The series in which the elements were set was determined by newland.
The law was not very successful because elements does not follow the same characteristics after mass no 40.
Octaves were discovered by Newlands. But it worked with lighter elements only, i.e., up to calcium.
The most detailed explanation of the law of octaves can be found in P.D. Ouspensky's book In Search of the Miraculous, which is a record of talks given by G.I. Gurdjieff.

John Newlands (1837-1907)
John Dalton was the first person to begin ordering the elements. He did this according to atomic mass. John Newlands developed this idea further and noticed that there were similarities in ever eighth element, he called this "the law of octaves'. Newlands called each group (column) of three elements a 'triad'
Before the modern periodic table , the concepts for classification of elements were given by Dobereiner , Newland law of octaves ,Mendeleev's periodic table.

His earliest contribution to the question took the form of a letter published in the Chemical News in February 1863 Newlands arranged 62 elements of the elements known then in a table based on their atomic weight. He discovered that in his arrangement schematic, every eighth element displayed similar characteristics. He proposed, for the first time ever, the existence of periodicity as a property of the diffeHe was one of the first, if not quite the first, to propound the conception of periodicity among the chemical elements. His earliest contribution to the question took the form of a letter published in the Chemical News in February 1863rent elements.Based on his discovery reguarding every eighth displaying similar properties, he wrote a paper wherein he proposed the Law of Octaves, in 1863.The Law of Octaves stated that an element exhibits behavior that is similar to the eighth element preceding/succeeding it. He arranged all the elements known at the time into a table in order of relative atomic mass.

Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Newlands Law of Octaves has many limitations, which are discussed below.1. This law was not applicable throughout the arrangement. It was applicable only till calcium.2. Newlands assumed that only 56 elements would exist in nature and believed that no more elements would be discovered. However, several elements were discovered in the following years. These elements did not follow the Law of Octaves.3. The positions of cobalt and nickel could not be explained according to Newlands Law of Octaves. He kept cobalt and nickel in the same slot. They were also placed in the same column as fluorine and chlorine, which have completely different properties.4. The properties of iron are similar to those of cobalt and nickel. However, iron was placed away from them in a different column.
The law of definite proportions was developed by Joseph Proust in 1806.
A bassoon can play 4 octaves.
