Always having trouble with Presto
No matter how much I practice, allegro vivace tends to be my dead on maximum speed except for a few lucky times. Allegro though is usually my maximum speed with no mistakes.
For example, as I practiced Solfeggio in C minor by C.P.E Bach, this is how I went about it:
1) hands separate, adagio
2) hands together, adagio
3) dynamics, adagio
And before I went on to the next step I made sure that I made absolutely 0 mistakes.
But as I try to speed it up further this happens:
7) Molto Allegro, few minor mistakes(wrong note for example)
8) Vivace, several mistakes, a few major(wrong octave for example)
9) Presto and Prestissimo, all wrong
There are a few lucky times when I was able to play it presto with 0 mistakes but usually it goes all wrong at Presto, no matter the piece.
This is a major problem for me. How am I ever going to play Toccata and Fugue in D minor if I can't do Presto with 0 mistakes every time. How am I going to play most of Chopin's pieces? How will I play extremely fast notes(like 64ths and faster)?
I have the right handshape all the time.
I make sure I have no mistakes at Allegro.
If I need to, I do it part by part.
And yet, except when I am lucky, I can't do Presto.
I am able to do trills and tremolos extremely fast. Why can't I do Presto? Why is Allegro my maximum speed without mistakes?
And how can I make myself able to do presto without mistakes when at Presto, no matter how few mistakes(0 or a few minor), it all goes horribly wrong most of the time? It should be as simple as wide and not so wide turns, tremolos, and trills and I am able to do those.
As for a piano teacher, I once had one but she got rude at me during my second year(don't know if it was because I wanted to learn more complicated pieces faster than the average person or what but she was rude about it). So from then on, I have taught myself how to play certain piano pieces.
Practice. That's the only way.
But for me, practice is not enough. There has to be something else I am missing for these very fast pieces.
