I have performed this improvisation with my plastic " sopranino " recorder in my house in rome , italy , 5 october 2015. I recorded with a tascam dr - 05 and i added a bit reverb with logic pro x.
I discovered freesound thanks to my music acustics teacher and i tried it this morning. I think it's very interesting and funny so i created a file on audacity software and i could load it here: it's my chihuahua's bark.
