There is no reason that any sampling rate over 44.1kHz should improve

Even if the music countains say 19, 8,, 4 and 1 kHz tones at the same
time? We know 19 kHz can be coded with 44,1 kHz sampling, but how about
the sum of the above frequencies?

What do you mean by sum? Do you mean the mathematical sum - ie 32kHz?
If so, it isn't there in the music. If you mean can all of those be
faithfully reproduced simultaneously, then yes - they certainly are.
Digital sampling really doesn't care what shape waveform it is
reproducing.

The latter. So 19 kHz with other 'tones' superimposed on it are no
problem at all?

None whatever. CDs simply wouldn't work if there were any kind of a
problem.
