Bach - complex, interweaving melodic lines, sounds heavy and intellectualMozart - lots of scales, crisp, makes fairly limited demands upon the instrument, fond of major keysBeethoven - frequently tumultuous, sonorous, pushed the pianos of the time to the limitMendelssohn - nice melodies, elegant and flowing, not very demanding of the listenerSchumann - very unpianistic, very few memorable melodies, bafflingly popularChopin - long, sinuous melodic lines, arpeggiated accompaniment, clever pedalling, beautifulBrahms - dark, dramatic, thick chords, sonorous, likes the bass register, superb musicLiszt - highly virtuosic, long chromatic runs, trills, exhilarating, harmonically adventurous later onDebussy - excellent at making the piano imitate other sounds, unusual harmonies, prettyRavel - elegant, virtuosic, crisp, vaguely similar to Debussy but sounds more refinedRachmaninov - massive chords, octaves, extremely difficult, intense, big melodiesScriabin - Chopinesque to begin with, highly chromatic later, bizarre, very difficultSaint-Saens - virtuosic, very idiomatic but almost totally lacking memorable melodiesTchaikovsky - highy melodic, memorable, not always particularly pianisticDvorak - highly rhythmic, tuneful, magnificent harmonies but awkward to play
Anyway, my point is that generalizations are dangerous.
Schumann - very unpianistic, very few memorable melodies, bafflingly popular
As for Schumann, I have made a consistent effort to listen to as much of his music as I can. I am familiar with many of his works, after all I have no desire to dislike somebody who has made such a huge contribution to the repertoire. I don't appreciate being accused of not understanding something that I have made a huge effort to get on with.And I actually like the Piano Concerto very much...
Perhaps you should try playing some of him. Your listening is clearly not doing you much good.
You're 100% absolutely right of course, how could I possibly have been so blinkered...?
No doubt we need to improve our listening and we need to spend all of our time playing a composer we don't like to satisy his "fans".
