This concert would mark the start of using theses (and other omnis) on piano as spaced pairs both in small ensembles and as hi-lites for concertos (sort of). The trick is all about spacing…. From the picture it’s vary obvious how far apart I placed them, and I caution you to use your ears when approaching this technique - my spacing needs might be much different than yours.
