Paolo Tramannoni from Italy has sent in this extraordinary Bass Clarinet demo.
He rendered this piece "Foglio 04.08" using the GPO Bass Clarinet with Sibelius on a Mac. It is in the style of Boulez/Berio - European classic contemporary music of the latest decades.
Paolo wrote several dynamic marks and hairpins in the score of Sibelius, then changed them to Control Change messages in Sibelius.
I asked Paolo if he was a bass clarinet player, and he said he was not but received several good suggestions while composing, both from his teacher (Alessandro Solbiati) and a clever bass clarinet player.
Thank you very much Paolo for sharing this demo!
