So we've all read about Chang's advice on getting a passage blazing 30% or so past performance speed, and Bernhard's preaching on making a passage easier for you to play as being the goal of practice.
How many of you think this is a sack of sh*t?
How many of you have actually tried it?
Well, if you haven't, go do it.
Today, I was practising Rachmaninoff's C#- Prelude 3/2. Using various practice methods, I was able to get the agitato section blazing so incredibly quickly that I couldn't believe my fingers. I mean, this speed laid Chopin's etudes to waste. I gradually slowed down to the speed required for this prelude, and I found that it felt like I was CRAWLING along. My fingers naturally wanted to go faster. Mind you, all this time, I'm playing all this absolutely perfect; not a flub in sight. I actually had to get used to playing so slowly, because it was SO EASY.
I didn't bother with this before, either. I deeply regret it. But hey, you learn from your mistakes, and hope you don't make the same ones again. Now the goal of my practice is to get the passage as easy for me as possible; so far, the only ways I know how to do this are to play in different rhythms and to play much faster. I find that the different rhythms contribute to increase in speed anyway, though.
I didn't apply this to the slow chordal beginning section, because I can play that without a problem as it is. The real trouble there lies in the musicality; making the notes whisper, playing the chords perfectly even, and bringing out the one note on the pinky. Speed practice won't help me any here.
Anyway, I just want to be a witness to the superior effectiveness of practising this way. Don't doubt it until you try it. Check it out, you'll be surprised with the results!
