i prefer CHOPIN but also i like beethoven, mozart, liszt bach, rrachmaninov...

In what aspect? Like the question asked a few days ago about what the
"hardest piece ever composed" was, this is a pretty impossible question to answer. Do you mean the composer who most accurately conveyed the emotions which he was trying to show to people, or the composer who wrote the most challenging music, or the composer who wrote the most enjoyable to listen to music, or the composer who wrote the most fun to play music, etc., etc....There is no "best" composer, unless you clarify in which aspect he/she was the greatest. If you were asking "who is your favorite?" I could answer that, because ranking often has nothing to do with favorites. My personal favorite piano composer (or at least lately) has been Rachmaninoff. I`m really starting to like all of the music of the Romantic composers.

Mozart rules! His music lives today as proof of the gap between himself and every other composer known to man. This is my personal opinion and I don`t care if anyone else doesn`t agree. That man was an absolute genius and I hear what he`s saying in everyone of his pieces. I can sit and listen to the Requiem from top to bottom and not move an inch until its over.

Bach definately...If not, he`d not be labelled as the `daily bread` of all pianists.

Errmm, well I would say Chopin if I had to chose just one, but there are SOOO many wonderful pieces for piano composed by different artists.

Though perhaps a little too modern and a little too processed for this sites main audience, Trent Reznor would be my pick. Being once a child prodigy on the piano he has held on to his keys throughout his career and uses them for underlying melodies and motifs throughout entire albums. Many times the simplicity of his work leaves me astonished that one can use such few notes at a time, and still create hauntingly new sound dimensions, after centuries of piano playing evolution... and I`m not speaking of the effects he uses, just strictly him and his piano. It may be hard to hear at times because of the layers and layers of industrial symphonies, but it`s there if you listen close. If you go so far as to extract his piano playing from his music and play it for yourself, you may find it extremely easy, yet extremely moving.

Concerning the studies by musical artists, its shows that Mozart is the master composer, then comes close to him Beethoven!

Then comes the rest...
