It is sometimes lawful under the copyright "fair use" doctrine to use another's melody and musical score to make a parody of the original song. A parody is the “use of some elements of a prior author’s composition to create a new one that, at least in part, comments on that author’s works.” Note that the new work, to be a parody, must be a comment on the original work or original artist -- NOT just a funny commentary on anything [though that funny commentary may be a "satire," a satire very often does not qualify as a fair use].
There is no way for anyone to pass judgment on whether your song is a lawful, parody or an unlawful infringement without hearing your song and the underlying song. And even then there is no one answer to whether the fair use doctrine would apply and, even more, no way for you to be conclusively protected by the fair use defense without first being sued and having to pay an attorney to defend that lawsuit. Weird Al Yankovich ALWAYS acquires a license to make and sell his parody songs. That should tell you that not doing so is a really bad idea.
The above is general information ONLY and is not legal advice, does not form an attorney-client relationship, and should NOT be relied upon to take or refrain from taking any action. I am not your attorney. You should seek the advice of competent counsel before taking any action related to your inquiry.
It depends on many factors, including fair use doctrine. You need an attorney's assistance.
Copyright is a form of protection provided by the laws of the United States title 17, U. S. Code) to the authors of “original works of authorship,” including literary, dramatic, musical, artistic, and certain other intellectual works. This protection is available to both published and unpublished works.

• reproduce the work in copies or phonorecords
• prepare derivative works based upon the work
• distribute copies or phonorecords of the work to the public by sale or other transfer of ownership, or by rental, lease, or lending
• perform the work publicly, in the case of literary, musical, dramatic, and choreographic works, pantomimes, and motion pictures and other audiovisual works
• display the work publicly, in the case of literary, musical, dramatic, and choreographic works, pantomimes, and pictorial, graphic, or sculptural works, including the individual images of a motion picture or other audiovisual work

Get a license from the original artist or get sued.
Whether or not they will win the suit is unknown, but any profit you made from the song will vanish instantly in court fees.
Q:"Is it legally okay for me to use the exact same musical beats from the original song for a music parody on a website such as YouTube where I'll be earning revenue?"
A: Yes, however I doubt what you have in mind is legally a parody but rather a comedic rendition that may be satirical rather than parody. To be safe you should obtain permission and a license.
