I’ve always played the Zingel version, and 99% harpists I know (I’m based in Germany) and – unless I’m mistaken – the lovely ladies that play in Bayreuth also play the Zingel edition. (Bayreuth = Wagner) 😉 Here in Germany it’s also the most common version to be played at an audition (if they want to hear the whole bit – but what’s expected at auditions is a whole other slice of cake!) I find the Zingel very well playable, and once you’re sitting in an orchestra it’s not nearly as scary as one might think! 🙂
