Too marvelous for words! This is an incredibly valuable tutorial, Melodica-Me. I don’t know whether I’ll outlive my bladder or not (B-24 bladder, that is), but there’s no place else where any of us could get this information. This is what Melodica World is all about. I may try replacing my bladder with a thicker one, or blocking one or two of those holes, to see if I can make it playable for me. The sound is so good. Fine looking Basso.
