I agree with what you say about Beethoven, it might be a bit controversial but I would imagine if he were around today you would see electric guitars & synth's (ala Yngwie Malmsteen) in his compositions.
In my humble opinion he is the foundation of heavy metal.
Quick update.
Working through Czerny book and doing the exercises.
I have been practicing in this order. spending around 1 hour on each with a 10 min break every 30 mins.
a) Scales
b) Czerny exercises
c) Bartok Mikrokosmos
Probably I am very slow compared to others but I am happy with my progression so far (early days yet! haha will see if I am still saying that 3 months from now.) decided to limit my practice as I don't want to burn out early, forming a routine every day is the key I think. (didn't want to practice 6 hours one day then miss 2 days) So far the practice schedule has been fine and I haven't missed a day so far.
I find it quite hard but its a nice period where I can see the progress from the effort. I wake up the next day and everything is a little easier than before, I don't make so many mistakes and the early exercises I can do without error.
Funny I thought learning an instrument would be all chin scratching/arty farty but its feels more like a weight training scheduled lol.
Surprised at Mikrokosmos, it has you playing both hands from the very beginning. I looked at the Beethoven sheet music but I want to tackle that when I can do it justice partly and also I am worried if i started it to early without the skills I would pick up really bad habits that would hurt me later.
As far as the theory side/music appreciation been listening to the TTC lectures, there are lots of tips on different composers to listen to so I am making a list.
Started listening to Max Reger & Nancarrow - blimey!
I started reading Piston harmony book, its quite in-depth but at least the language is easier on the eyes than the Schoenberg books (I tried to read the theory of harmony, but after a few pages I realized I wasn't understanding what I was reading - and English is my first language.. believe it or not lol.).
I took your advice and decided to look at the things that interested me also, so I figured it would be interesting to look at early church music and how chants work. There were some great resources on youtube.
There are also a number of great books on chant that are online however the notation is diffrent to western musical notation. but Lucky there are a number of online courses in how to read the chants.
Chin scratching tastic - now i can take the melody's for my compositions!

Greek:
Will keep plugging away at it.

Cheers!
