And thanks again 
hehe...About heller:
Yes I mean the opus 46, 47 and 48 etudes. He said that this set has all the basics like scales, musicality! etc. on a rather "easy" level. And I have to agree with him I really learn from them. But don't you think it is pretty difficult to find pieces on my level that I like with the same principle.
What is your level? If it is between levels 5 - 8, most of the piano repertory is actually at that level - and some of the most beautiful pieces ever written.
You see, up to the beginning of the 20th century there was a huge market for sheet music for amateur players - since there was no TV, no Radio and no computer games, almost every middle class house and above had a piano, and it was the focus of the fmily leisure. So composers could not just write ridiculously difficult pieces. They had to write wonderful pieces, with a certain degree of difficulty (preferably they should sound more difficult than they actually were) so that amateurs could tackle then. Heller fits in just this market.
But also, most of Chopin´s pieces (the Waltzes, the Mazurkas, several of the preludes, some of the polonaises) are not that difficult and fall well within this range of difficulty.
All of Mendelssohn´s Songs Without Words (which can claim - as your teacher said of Heller - to have "all the basics like scales, musicality! etc. on a rather "easy" level").
The great majority of Scalatti sonatas (over 450 of them) are also on this level of difficulty, and so is a good number of Bach´s keyboard works.
Handel Suites, Haydn sonatas, most of Mozart´s solo keyboard works are also within this range of difficulty.
Between grades 5 - 8 you will find numberless works by Beethoven (including several sonatas), by Schubert, by Schumann, by Kirchner, by Hoffman, by Fibbich.
You can add to them Prokofiev - which has a number of easy and yet highly effective pieces, Shostakovitch, Gliere, Borodin, Karganov, Rebikov, Liadov, Kabalevsky.
The list goes on and on and on.
And these are only the most famous and well known composers. If you decide to explore the more obscure composers (especially women composers like Amy Beach, Fanny Mendelssohn, Cecile Chaminade, and so on) You will be overwhelmed with the absolutely wonderful pieces totally within your reach.
It is no secret I love Scarlatti, but I would never suggest to anyone (unless they wanted to do it, of course) to learn all 555 sonatas (there are many that I confess to find dull).
Or to learn all 48 SWW by Mendelssohn or all 376 "Souvenirs" by Fibich.
And the main reason for this, is that there is so much wonderful repertory out there that I cannot afford to waste time learnig what I don´t like.
Moreover, it is exactly in the variety of pieces/composers/stules one learns that the range of technique at one disposal will be found. For all my fondness for Heller, there is much that he does not cover - no composer can cover everything.
Like with food, you want variety. Eat just one kind of food and you end up sick.
Best wishes,
Bernhard.
