Thanks, Sedayne - I see what you mean: really just setting up a keyboard similar to bagpipes, with one (or more) notes taped down as the drone(s); but what I like, and keep trying, to do is play like I sing / and sing like I play (with both recorder and keys), and I sometimes go through the chromatic scale on my tenor-recorder to help with this (see myspace) - indeed, I've read/heard that recorder comes from the olde-English word "recorden," which means to warble or sing.
