Is this a fairly good cross section of what would be considered standard modern rep.

Barber Piano Sonata
Corigliano Etude Fantasy
Liebermen Gargoyles nd Impromptus
Ginastera Piano Sonata No.1
Berg Piano Sonata
Webern Variations

Anything to add?

Lots of things to add:

Prokofiev sonatas
Shostakovich Preludes and Fugues
Ligeti Etudes and Musica Ricercata
Bartok Sonata and Out of Doors Suite
Messiaen Vignt Regards sur l'Enfant Jesus
Schoenberg piano works opp. 11, 19, 23, 25, and 33
Rorem Sonatas and Barcarrolles

and lots of other very important works are in the standard concert repertoire

Isnt there some Hindemith in the fold? I stayed fairly clear of 20th works in school, but did accompany a clarinet on a sonata by Hindemith.

Terrible to sight read. And I couldnt make heads or tails of it musically.

Hindemith's 3rd piano sonata is performed with some regularity, but he is really more known for his sonatas for piano and another instrument (piano and timpani, for piano and trumpet, etc.)

Those are all wonderful works but I certainly wouldn't consider the Ginastera, Berg or Webern modern.

Don't play Gargoyles, it's as cliched as it gets these days.

True; and Liebermann has written a lot of really good music BESIDES Gargoyles.

Hard to say what constitutes "modern," but here are some important works. Some get played, some don't...

Crumb - Makrokosmos I, Little Suite for Christmas
Davidovsky - Synchronisms #6
Adams - China Gates, Phrygian Gates
Bolcom - 12 New Etudes
Lees - Fantasia
Xenakis - Ervyali, Herma
Griffes - Sonata
Rzewski - Variations, North American Ballads

Were you a music major in school, and went on to another field afterward? Just curious because that's what I did.

Another piece that could be played more is "From My Diary," by Roger Sessions.

Yup. Thats what 99% of music majors do. LOL

Nope, that's what most Bachelor of Arts and many performance majors do. Most of those in music education degrees end up having careers in music.

Among the moldy 20th century music that is called modern I would certainly include piano music of Poulenc and Milhaud. But there's lots of other stuff.

Yes, I was a performance major. yes, education majors find jobs teaching.

hmmm scary stuff. too bad I'm too stubborn to give up on being a music major. but I do have a plan! bachelors in performance and hoping to get my doctorate in pedagogy or musicology or something... one can never tell. there has to be a university somewhere that would hire me! *really doesn't want to sell insurance or work in a cubicle*

I really love the Shostakovich preludes and fugues. his third fugue in G in particular is really nice. and Crumb's suite for Christmas is really cool too.
