"比的原理" is a Chinese personal website centered around "scientifically appreciating pop music." The scraped main text explicitly states, "This site focuses on how to scientifically appreciate pop music; this site does not discuss how to sing well," making it more of a musical acoustics/pop music analysis knowledge site rather than a vocal training or formal online course platform. The site also provides access to tools like an online pitch tester, online piano, and absolute pitch test, and links to content such as "learning the basics from scratch."
The course domain mainly focuses on pop music appreciation, pitch, acoustic spectra, and spectrum analysis. Discussions about Fourier transforms, digital signal processing, resonance, and sound pressure frequently appear in the comments section, indicating a certain technical and analytical tone to the content. Regarding the teaching format, the main text shows no signs of live classes, recorded broadcasts, or 1-on-1 courses; it is more like self-study through articles and tools. There is no information regarding certifications or certificates. The language of instruction is Chinese. In terms of instructors, the webmaster interacts in a personal capacity and stated in the comments that it is "just an amateur hobby," without disclosing any formal teaching institutions, academic qualifications, or professional credentials.
The scraped content shows no course prices, membership systems, or payment methods, so it can be determined that the public content is primarily free to browse, though it cannot be inferred that all resources are free. Service support relies mainly on community interactions such as the comments section and 贴吧; however, some external homepages are marked as "abandoned" or "unable to log in," and the webmaster has also stated they "basically no longer research this," indicating weak capacity for continuous Q&A and updates.
The pros are its unique positioning—understanding pop music from a more rational acoustic and signal analysis perspective—which suits users unsatisfied with ordinary music reviews; the accompanying tools also help with pitch perception training. The cons are the lack of a systematic course structure, learning path, and homework feedback, making it unsuitable for those looking for guided learning from scratch; additionally, it explicitly does not teach singing, so users looking to improve vocal techniques, breath control, or resonance training should seek a vocal coach or professional courses.
It is suitable for music enthusiasts, music review writers, music academy students, or self-learners interested in audio analysis. Regarding access from China, the domain itself appears to be directly accessible; however, external links like YouTube will be restricted domestically. Alternative choices could include music theory/acoustics popular science videos on B站, music courses on 网易云课堂, or more systematic audio signal processing courses.
