Is separating music copyright infringement? How to use it right
Does separating a song for personal listening infringe copyright, what to watch for posting covers, and how Content ID treats separated tracks.
Does separating music for personal listening infringe copyright?
No. Running a song through a technical tool to listen, practise or study arrangement is not infringement, as long as you already have lawful access to that recording (bought, or streamed through a properly licensed platform). It is a technical operation on a file you are already permitted to hear, similar to adjusting EQ or trimming a clip, not an act of exploiting the work.
Under Article 4, clause 8 of Vietnam's Intellectual Property Law (consolidated text, amended 2022), a reconstruction built from an existing work, such as a translation, adaptation or arrangement, falls under "derivative work" and only requires permission once that derivative work is published, distributed or exploited. Separating stems for private use, never published outward, does not fall into that permission-required category.

Copyright and related rights are two separate layers
Vietnam's IP law separates two layers of rights over the same song. Copyright (quyền tác giả) belongs to whoever wrote the music and lyrics. Related rights (Article 17) belong to the performers (singers, musicians) and to the producer of the sound recording, meaning whoever financed the specific recording you are separating.
Splitting a recording into stems erases neither layer. You are only performing a technical operation on the recording; ownership of the work and of the recording stays fully with the composer and the producer.
Article 25 of the IP Law (as amended 2022) permits copying a reasonable part of a published work for personal research or study, non-commercial, without needing permission or paying royalties, provided the author's name and the work's origin are credited. This exception does not apply to architectural works, fine-art works or computer programs.
Article 25a (added in the 2022 amendment, effective 2023) adds a separate exception for people with disabilities: copying or presenting a work in an accessible format is allowed once lawful access to the original exists. Both articles are scoped to personal, non-commercial purposes; neither extends to publishing the result publicly or monetizing it.
What to watch for when posting a cover on YouTube or TikTok
Separating a beat to practise or film a cover is a technical step, but the platform and rights holders only really get involved once you publish it publicly, not at the moment of separation.
On YouTube, every uploaded video is scanned by Content ID, a system that matches audio and visual content against a database submitted by rights holders. A cover video can receive a Content ID claim if it matches a registered recording or composition, even when you only sing over a self-separated backing track.
Per YouTube's official cover-monetization policy, a cover video only shares ad revenue once the music publisher has claimed the song through Content ID and opted to monetize it; if the song has not been claimed that way, you cannot enable monetization yourself. Using the actual commercial recording, including a ready-made instrumental or karaoke track, is not eligible for monetization at all.
On TikTok, the General Sound Library is licensed for personal, non-commercial content only. The moment a video promotes a brand, product or service in any capacity, TikTok treats it as commercial content and requires the separate Commercial Music Library, a pre-cleared catalog built for that purpose; major-label music (Universal, Sony, Warner) is currently excluded from that commercial catalog.
Can a separated beat be used in a sales or ad video?
Not without permission or a commercial usage licence for the original. Sales videos, ads and any content with a commercial purpose fall outside the personal-use exception in Article 25, and that is exactly the line TikTok's commercial music policy above is enforcing.
The safe path: use music with a clear commercial licence (a platform's commercial music library, a purchased licence, or your own original music), or contact the composer or the recording's producer if you specifically need the separated track.
How does Content ID treat a separated track?
Content ID matches the audio fingerprint of an uploaded video against a reference database; it does not care how many layers you separated before recombining them. An instrumental pulled out and used as a backing track still carries the original recording's fingerprint, so it can still be matched and claimed exactly as if the full original recording had been used.
In other words, separation is a technical processing step, it does not "erase" a recording's copyright signature. Whether you get claimed depends on whether the rights holder registered that recording with Content ID, not on whether you separated it into stems first.
When do you need the rights holder's permission?
By contrast, personal practice, learning arrangement, musical analysis or singing karaoke at home usually needs no permission, within the personal-use scope of Article 25. See the more detailed breakdown in removing vocals: how-to and real limitations.
- Publishing a separated track, or a video built on one, to social media, YouTube or TikTok with monetization enabled
- Using it in commercial products: ads, sales videos, sponsored content
- Distributing or reselling the separated result in any form
- Releasing a new arrangement (a remix, an official cover recording) built on the separated result

Does using a tool like Tách Nhạc automatically infringe copyright?
No. The technical act of separating a recording you already have lawful access to hear does not by itself infringe. Infringement arises once you publish, distribute or monetize the result without rights to the original.
Can posting a cover with a self-separated beat get copyright-claimed on YouTube?
Yes, potentially. Content ID matches the original recording's audio fingerprint regardless of how many layers you separated, so the video can still be claimed if the song is registered with the system.
Is using a separated track in an ad or sales video legal?
Not without permission or a commercial licence. Both TikTok and YouTube distinguish clearly between personal non-commercial content and content promoting a brand, product or service.
What is the difference between copyright and related rights for a song?
Copyright belongs to whoever wrote the music and lyrics; related rights (Article 17) belong to the performers and the recording's producer. Separating stems does not affect either party's rights.
