I believe the official name of what you are doing is derivative work .

A derivative work is a work based on or derived from one or more already exist- ing works. Common derivative works include translations, musical arrange- ments,.........reproductions, abridgments, and condensations of preexisting works.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
