And that's not to mention the tuning of the concertmaster's violin "scordatura," or up a tone, to create a harsh sound symbolizing the dance of Death of the second movement scherzo.
Death has the power to call forth the dead from their graves to dance for him while he plays his fiddle represented by a solo violin with its E-string tuned to an E-flat in an example of scordatura tuning.
Now for a bit of dark humor: In an earlier version of the piece to be performed on the MATA festival, a rather extreme scordatura in the cello is required.
Since that incident, I have modified the scordatura.
In short, my attempt at creating a simple piece resulted in a fast microtonal composition for singing violist playing scordatura while using extended vocalizations.
Timbre anyone?...and Pianos are not tuned in the same way as a guitar so it is very possible that unless the piano was only used for 1 note (the F in question) the dissonance in tunning (guitars are tuned in perfect intervals and pianos are slightly out of tune by nature), there would have been a dissonance found in some of the other notes vis a vis the imperfectly tuned piano against the guitar(s)....also there is 2. scordatura tuning which means that the "g" on the guitar could well have been retuned to an "F"
