This publication is a retelling of the article by Charles Wheatstone printed the same year in Quarterly Journal of Science, Literature and the Arts. Lobachevsky mentioned the author as a third person, emphasising the important parts and letting out the unimportant ones.
In this article the laws of resonance were applied to the different musical instruments and other objects. This among with other texts led to invention of concertina by Wheatstone in 1828.
Among the interesting notes by Lobachevsky we read: ‘I don’t know why the author says that Englishmen and Germans use the similar notation. I had to change the titles in English original to German system that I used when I studied the music’.
In the same periodical ‘On the Basics of Geometry’ was printed 5 months later.
