the beauty of these things is that unlike a flute or a recorder, placement of the holes has nothing to do with the notes, it's the size and number of them. thus you can tune and arrange the notes in sequence to play a melody by running your fingers down them in the order they appear if you learn to make your own. yes, i did just make that up and it's all theoretical but i don't think it's too far fetched. correct me if i'm a little or way off.
