I am now doing some research on Brahm's essay, Octaven u. Quinten. I cannot read German, so I cannot do anything with the original manuscript. I have read some secondary sources about this essay, but they only summarise the main topics without going into details.
Is there an English translation to this essay, Octaven u. Quinten? It does not have to be an exact translation. I am just looking for an article that includes Brahms's main ideas, including exactly what types of consecutive fifths are considered appropriate or inappropriate by Brahms.
