Class concert Waltraute. But, after listening to most of it, I have the same impression as the one I depicted above. It's all over the place, you have all the instruments, all the range of voices within the singers, and it "leads" me nowhere.
Mozart is one of the only composers whose music (not all his music of course) I have trouble delineating, structuring.
If you take this bit of Beethoven's 7th symphony, there is a clear musical path that is used and varied throughout. None of this in Mozart's work where succession of notes have, in my eyes, little in common with one another.
But your missing a fundamental point here Nani
Beethoven has to control every aspect of his composing and Mozart less so it's in his character
Your example is, i think, the third movement of that piece which is a theme and variations so variety is the corner stone of that form -
1/ simple tune
2/ now develope it with as many variations on the tune as you see fit
Thats a stock in trade for composers of any stature be they Mozart Beethoven or the lesser lights say Moschelles Czerny etc.
This is why Beethoven has an affinity with Haydn and less so Mozart. Haydn's music is carefully and brilliantly crafted and is a very good example of how Beethoven took many of these 'forms' and developed them in a very 'unMozart' way
This is touched upon by hungrywing who has marked the whimsical nature of some of Mozart's work - however that merely hides what lurks beneath the often simplistic melodic structure - a fine control of all the forms and an almost Chopinesue leaning to wander off the beaten track for a moment of harmonic uniqueness and magic
It is shown in the way the method of composition by both Beethoven and Mozart
Beethoven, a very methodical worker, continuously sketching and rewriting a work, that often went on getting ammended for years untill he was happy with it, he was noted as often being "knee deep" in paper
Mozart, a miraculous, and it really is in my opinion one of the true wonders of this earth and the pinnacle of artistic achievement as far as i know unmatched, that he could literally wake up with a finished composition in his head, write it straight to manuscript, no alterations, straight off to the printer and it was finished with no or hardly any ammedments. This was often the way he worked and it's quite staggering that so many of his pieces are practically snapshots of perfected finished music that needed no more polish!!
Everytime I think about this as a musician myself, I still find the enormity of this difficult to grasp
This 'lightness' is something that s extremely difficult to interpret as a performer, without the music coming across as 'feeble' and often 'ineffectual'
Piano is my instrument and from that point of view too many pianists play his music too lightly when actually the musid has huge poignancy and gravitas but I'll admit this is difficult to convey. Of all the composers I have played Mozart always confronted me with problems of interpretation
Beethoven in comparison is much easier as you can hear quite quickly the point he's making as it's often right in your face
Fortunately for us though we have them both and of that we ought to be grateful - both at the top of the classical 'tree' along with Bach imo
