Interesting how he starts politely ("dear sirs..") and then degenerates from there.
I don't think there's much substance to this argument. Firstly because it is a matter of taste. But secondly
because Liszt and Chopin, though contemporaries, are incomparable stylistically. Liszt was a dashing showman; Chopin seems more thoughtful to me, and I believe his etudes show that he is more concerned with acquisition and sharpening of technical skills, whereas Liszt's etudes demand technique but do not each as much.
By the way, weren't Liszt and Chopin friends? (Liszt was not, as this man claims, Chopin's "mentor," was he?)
I find this argument to be full of insubstantiated, unsupported points. I take issue with the following unfounded points:
1) That most of his nocturnes are
"byproducts of copy and paste."
However, the author does not bother to prove
how they are byproducts of copy and paste. There is a difference between adhering to form and recycling. Adhering to form is a respect used by the great composers, all of them: Bach, Mozart, Haydn, Beethoven, etc.
2)
"Warmongering polonaises."
What does that mean? Differentiate between nationalism and war. The addition of the adjective means that the author has inserted context into the polonaises that have formed his opinion (when they were written, etc.).
3)
"A few warhorses here and there in the modern repetoire."
I think you will find that there are many more of Chopin's pieces that are still popular as opposed to the number of Liszt's, which are generally played only for showmanship.
4)
"Without impressionism, there'd be no Jazz nor atonal music."
In many, many places in Chopin's music, you will find jazz-like construction, as well as clashing sounds. Off the top of my head, I have analyzed the E minor prelude for the jazz, and Op. 10 No. 2 etude for atonality, such as minor 2nds used.
5)
"And, did you know that Liszt is the progenitor of the practice where frenzied young ladies flinging their personal items to their idol on stage?"
Yes. That's something to be proud of.

6)
Something Chopin lovers just don't have sufficient nerve endings or heart to ever discern or appreciate. Them vapid weepy heartburned half-asleep day-dreamers; tears of emotion gushes out their eyes like faucet, heaving and snorting to express their stupefaction and gratification.
Well... I thought we were discussing the composers, not their fans. This does nothing to address the compositional matter. And, it's never completely wise to personally attack those who you disagree with.
7) .
Look at his greenhorn-friendly nocturns, for which this wimp is most famous for. Out of the 20 or so, maybe 5 are good. The rest are soporific bore
Opinion. Why bother arguing with it?
I object strongly to name-calling in writing like this. It devalues what could be an intellectual piece.
8.)
Once in a while there's a gem like the Revolution or Raindrop
Many will say, these are not his greatest works. If that is what the author believes, he must then not have delved too deeply into Chopin's works.
9)
Bland finger exercises masquerade as musical etudes:
Chopin's etudes are not pretentious enough to create fireworks; rather, they deal with the difficulties that face pianists in everyday repetoire. Thirds, sixths, octaves, chormatics, arpeggios, rolled chords, etc. -- these are what are the foundation of a solid technique.
10)
The prelude set in Bach's Well-Tempered Clavier is sufficient to dwarf Chopin's ass.
Again, apples to oranges. Opinion. Dissect is and show me why; analyze it for strength and weakness, and then you have an argument.
11)
greenhorn-friendly nocturns
What exactly does this mean? This person makes poor choices of adjectives.
12)
and the mazurkas being the worst form of music in entire history
Or, perhaps... 3-chord looping in rock and roll... 2-chord looping in pop... thumping in rap...
13)
Out of his petite collection of preludes,
Yes, but... really, you could name any of his shorter pieces preludes as well. Then he would have written more. But he chose to move on to different material, never returning to preludes.
14)
Nary a one piece is worth listening to once.
There is nothing that is not worth listening to once. Anyone who thinks so should open his mind; how can you possibly appreciate something after only one listen?
I have more complaints about this disgusting person's argument. However, I will not waste my time here. I'm going to go practice Chopin.
The real testament is that, after more than 100 years, Chopin is still much more popular than Liszt, by volume and percentage.
