My hardware isn't up to listening to music clips, but I'd second what several have said, and add this: Jeeniea [I'd love to know if the male version of the name is Jeenius!!] mentioned getting the NAME out: in that context, strong names will help. The point about tune names is that their appropriateness is in the ear of the be[er]-holder. If you gave them original (poss. surreal?) names consistently, you might get a name [brand] for that, which might aid memorability.
Unless the software doesn't allow it, you should be able to indicate stuff off the stave by using an 8va line, where the notes are written an octave higher/lower than played. Players familiar with note-names won't struggle to transpose and it makes it easier to sight-read. Only works for fairly continuous sequences (you can't easily annotate an odd quaver/8th-note as a one-off or a repeated series of leaping intervals) but there's nothing to stop you writing ALL the notes in that sequence an octave away from where they should be, even if some notes at pitch would still be on or near the stave. I'd imagine music software struggles to deal with printing 8va markings, but worth looking into. If you're not familiar with this principle (it prob. doesn't arise in folk notation much), I'll have a look myself (though probably not within the next fortnight) and report back. I'd be interested to try musescore, as I'm always open to anything free!!!
