Here is another example from my project "Pianostudents playing with big orchestra". Here I have arranged a short piece by Lennart Brage from one of his pianobooks for educational purpose.
Here I use both GPO and JABB.
In the concert I totally had 6 percussionplaysers. Most percussion students only want to play drums (rock!) but I want them to test the reality of many percussion player, 1 triangle stroke, 30 measures of rests etc. Also to play many different percussions, so even if it was a "piano concert" the percussion players also made a lot of experiences.
In this piece there is a vibra throughout the piece and drums with brushes, which was something totally new to the percussion player.
