Simple, Stylish Songs for Piano

Rufus Wainwright's "in a graveyard" from POSES...not exactly uplifting...but very musical...

Forgive me for initially failing to notice your disdain for "cheesy EZ piano arrangements". If you like outstanding charts, I strongly recommend you purchase "The New Real Book" published by Sher Music Co. This is a collection of scores of standards and other classic tunes. (Nature Boy is in this book.) The charts are not sappy EZ charts, but are true to the composers' originals.

As a gigantic bonus, they list the recordings from which the charts are derived in the back of the book, so you can get the record and get some inspiration.

I bought mine in April 1977, and although it is soft and tattered from use, I still find something of interest everytime I pick it up.

How about some Noel Coward or Alec Wilder songs? Coward's songs are funny and clever while Wilder's songs are poignant. The latter are especially easy to sing as the range is not too wide for most people. One of my favorites is "Blackberry Winter".

Skip the singing and learn to orchestrate "Over the Rainbow".

My personal favorite retrospective piece anyway when done as an instrumental (leaves the rest to one's imagination).
