Thanks Adodd for your clarification.
sorry dcstudio, I'm not at all matching your description

my friends actually mock me for wasting so much time playing and I don't have any relatives playing the piano to look up to, although I do admire some famous contemporary pianists that don't have anything to do with my family

and to whom I listened to before started playing (Herbie Hancock, Hiromi Uehara... ). I do know what "obscure terms" like polyrhythm and circle of 5ths are because I study theory and also I played other instruments in the past: drums recently for a few months (all drummers always mention polyrhythms

) and bass guitar for many years (played 60-70s rock music in a couple of bands as a teenager. Even took lessons with a teacher for one year. Yet somehow I progressed more in one year of self study at the piano then in several years of playing the bass).
But apparently you had some bad experiences with some of your students, so I totally understand where you're coming from.
1piano4joe, thank you very much for your very clear advice. Also, Chopin's Waltz in A Minor seems very interesting indeed. Doesn't seem so easy though

but I might include it in my wish-list.
Thank you also keypeg for your perspective.
I hope nobody will get offended if I say that it seems to me that some people on this forum are a little bit too judgmental and fast at jumping to conclusions and making suppositions about other people. There must a lot of guys who come here like with the objective to play the Appassionata as their first piece ever, so I understand your frustration with this kind of request, but even in that case, you know, live and let live. They might not have the same objective that you have at the piano. If their goal is only to play the Appassionata and nothing else, let them try to do it. Also, as I thought to have clarified in my previous post, that is not me: I don't have just the Clarfield list to follow; with Burgmuller, ABRSM, scales, arpeggios, reading, theory, etc., I honestly don't think that this is such an absurd study plan (which anyway, once again, is not the subject I was asking advice on in the first place), but I do recognize that the topic title I chose was a liiiiiittle bit misleading.
In any case, I'm just back from my first experience with the teacher. The previous student was working on a Burgmuller piece, so I thought "this bodes well". The guy is kind of... errr... not very young

and the time is very limited (30 minutes) so I didn't have the possibility to explain everything in detail. In any case, first thing he asked me to play a couple of my pieces for him. I played the Minuet in G and Fur Elise. I made a couple of errors in both pieces, as I expected

He said he was quite impressed with my level and that also the position of my hand seemed alright. He only wasn't convinced by the fast part at the end of the second, ehm, variation (sorry, I don't know the technical term) of Fur Elise, as the notes were uneven.
So he made me work on some scales and arpeggios with particular emphasis on the thumbs and wrist movement in order to avoid unwanted accents and rigidity of the hand.
Then we worked on the first Hanon exercise and some variations of it to work the weak fingers more.
Finally he asked me what other repertory I wanted to tackle, I started listing the Clarfield pieces and after one second he kind of lit up and exclaimed "the Solfeggietto! We should work on this, it would be great for you!" so I was like "well, ok" and I took the sheet of the piece as I had it on my tablet.
While working on that he recommended that I work on my reading skills, on which I totally agree.
He didn't say anything in particular about the Burgmuller Op 100, so I think I will continue studying on it, but I will bring it up more in detail next time.
So, for the moment I'm moderately satisfied with the whole thing, but I will refrain from giving a definitive judgement. The teacher seems open enough on the repertory and also offered me some new insights on stuff that I had already done (namely scales, arpeggios and hanon). Let's see how it will go next time

Thanks a lot once again everybody for all your replies. Cheers!
