Nothing has changed within the folder hierarchy.  Note that there's not 
one single folder at the top of the hierarchy, there are about 15 
folders that were originally at the top level of the partition's 
directory of the external drives.  (Now I've moved them into a top-level 
folder in my user account in the internal drive.

iTunes is also maintaining its regular iTunes folder hierarchy in the 
Music folder in the user account, with its iTunes Music or Media 
folder.  That's all still in place, and my music is located on a 
different volume, as described in the previous paragraph.

The name of that folder shouldn’t matter, unless iTunes’ keep organized box contains a check mark, in which case iTunes will override your own organization performed in Finder for music it’s aware of.  That could make it difficult to know exactly what music content iTunes is trying to manage.

If items inside the hierarchy have been moved and/or reorganized since iTunes was able to locate them, then you may have to manually update iTunes’ records of where those item currently exist by responding to iTunes prompts when it fails to find something. Have you moved things around in the hierarchy of your music then found that the keep organized setting was engaged upon launching iTunes? That could have unexpected results.

Nearly all the music is on a partition on an external drive, organized in about 15 main folders on the root directory of that drive, with lots of sub-folders within each of the main folders, most of which have sub-sub-folders -- none of which has anything to do with where iTunes would normally store music.  So the locations of the iTunes Library or the iTunes Music/Media folder have no bearing on this.
