But they must be done. Just because the piece is written by one of the most brilliant geniuses ever stepped foot on Earth, it doesn't mean that we can simply play the notes and expect magic to happen.
Mozart was a composer. Composers write ideas. But ideas require voices so they can be uttered and heard. So long as there are musicians, Mozart will always have voices. Right now, we are one of his voices. And the voice will have a better effect on the audience, if the tone of the voice properly reflected the tone of the idea. Therefore, the voice always needs a brain. Obviously we have one in each of our heads. But we have to use them to understand the music. Who was Mozart? What was his ideal? What were his values? What was his philosophy? What was the world around him like? What was he influenced/inspired/fueled by? Who did he want to be? Who was his audience? What/How did he want us to think?
These are the things we need to know, and mix it in with our own imagination inspired by his notes on page, and only then, we can have the "proper tone".
Obviously, this goes with any piece of music you will ever play. So no, Mozart does not get a special treatment, ever. Every music has characters and ideas. Some deeper than others, but nevertheless they all require some degrees of understanding and imagination. From J.S. Bach to Busta Rhymes, from Ravi Shanker to Dean Martin.
For Down on the Corner, I'm glad many of you found the recording I made helpful. Decide on EXACTLY what you will play for each section, then all you do is practice going through different sections (take a couple at a time, then eventually the whole song). I'm so glad it's coming along!
