The organillo is a Spanish player piano involving a cylinder, a hand crank, and a piano harp. This particular instrument dates from the early 20th century, and is in a wonderful state of disrepair. It also includes five bells.
My improvisations involve the use of the crank as well as manual manipulations. I have made no attempt to “prepare” the instrument. Much of my interest in this instrument is its unique state due to the process of entropy.
