Fast double stop thirds
Hello all, I was wondering of anyone knows any etudes or excersizes that help improve fast doubles stop thirds such as the ones in pieces like Wieniawski Polonaise in D Major or Carmen Fantasy?
You may choose from six books of
Dounis, and basically any scales excersise in thirds with rythms .
In many cases practicing etudes will do no good in correcting a problem.
I'd make the possibly obvious, but possibly crucial, observation that to tackle problems with fast thirds the best thing to do is to play very, very slow thirds with careful attention to every movement you are making.
Simon Fischer's new-ish Double Stop book contains lots of preparatory work that clears the way for faster double stop playing. Without knowing what the difficulty is, it's hard to make a real recommendation, but his exercises will cover all the common ones.
The technique used to get a fast tempo involves a feeling that the hand is in constant motion. To practice this, flex the wrist slightly in and slowly slide audibly from 1st position to 3rd, feeling that fingers 1 and 3 are pushing 2 and 4 out of the way. As soon as fingers 2 and 4 go down in 3rd position flex the wrist slightly out and slide slowly down to 1st position with 1st and 3rd finger leading the action. This is the technique that Ysaye passed on to his students.
I found the following sequence of things helpful (note that this took me a quite a long time on each step) -
We often have to adopt a rather extreme hand & arm position to allow the fingers to drop rather than grope.
