Talk:Frequency ratio
Extended Frequency Ratio Section and Table of Contents
The recent additions are way too much for the page. It went from simple and clear to cluttered and confusing, which is not appropriate for a beginner page. I recommend removing the table of contents and the Extended Frequency Ratio section entirely as it touches upon more advanced topics that are discussed more clearly elsewhere, and the body has now been updated to include mention that ratios with more than two terms can be specified as extended ratios if necessary. This simple fact shouldn't take up half the page or be presented as something entirely different than ratios with two terms.
Furthermore, the statement that these are called "EFRs" or that subharmonic series chords are called "SEFRs" is incorrect. This term was made up in recent times simply because the actual term wasn't known, so presenting these as things beginners should learn or as things people commonly use is inappropriate.
