I think if you're doing the tune as a MIDI so other folks can learn it, it's best to go simple - especially if it's for printing sheet music. Those dots can be difficult for some folks to figure out and simplicity also provides room for a bit of creativity.

Right. Look in any old song book, and you'll hardly ever find any dotted notes, and barely a rest to a measure, except at the beginning and end of the score -- usually just quarter notes, half notes and eighth notes. Not only does it make it easier to pick out the melody for those who are dodgey with reading music (as I am, truth be told), but it allows for flexibilty in emphasis and inflection.

And I will be doing this as sheet music. I'll be submitting this to a Pagan writers' webzine due to come out around Yule (Along with another song I've done -- also with help from Mudcatters, which can be found here).
