I have been transcribing a piece in 6/8 time which has two voices. I am worried that it is difficult to read the rhythm and was wondering if there is any other way to format this to make it clearer. Is this a matter of opinion or is there a "correct" way of doing this?
Let’s start with the elephants: The two voices in the bottom staff have their stems in the wrong direction, and using a tied 8.+16+8 instead of a simple 4. is not really optimal. Then you should try to align the middle voice to the beat structure. Also I suggest not to use 8. 8. in 6/8 of division in two but rather duoles. But then one might argue that may you want to notate this in 2/4 and use triplet for division in 3.
See here two examples of how I would lay something like this out:
Just to add one other option to Lazy's two, the need for tuplets could be eliminated by writing the passage in 12/16. Stopping short of recommending this (12/16 can be awkward to read), it's an illustration of the flexibility of time signatures, beaming, and ties.
