A professor I knew a few years ago did her PhD part-time and her advice was don't.

In your situation, I'd stick with journal articles for the time being and wait until I've accumulated more knowledge and experience before considering book chapters; and then I'd want to write the whole book, not just a single chapter.

The question you asked has already been answered and the consensus seems to be to go for the journal article: https://www.researchgate.net/post/Article_publication_or_Book_Chapter_which_one_is_considered_more_important

I suggest you check the degree regulations. They'll specify exactly what you need to do to get a Distinction.

With my MSc in Statistics, the requirements were 70%+ in 2/3 of the modules, including the dissertation, for a Distinction, 60%-69% average overall for a Merit and 50%-59% average overall for a Pass.

UCL offer a PhD in Albanian Studies, but there's no funding:

The funding is for three years, but I would expect that you would be allowed a fourth to finish writing it up and get it submitted. At my university, the fourth year cost me £750 in fees. There's a nursery at mine, so that's something you might like to check out at your prospective university(ies), although not all of the 40 hours a week others have mentioned would have to be on campus.

Another possible outcome is revise and resubmit.

The Birmingham one is accredited too according to the APM:

I got two journal articles and a conference paper published before I submitted and I'm preparing two more journal articles while waiting for my viva. My field is colour image processing.

A PhD is basically a training to do research and to write journal articles and the more you can demonstrate to the examiners that you can do that, the better. At school I was taught to always make things easy for the examiners and the more of your thesis that has already been peer-reviewed, the easier it'll be for your PhD examiners to pass you.

You should be able to request everything you need through your university's library, at no cost to you.

With all the Brexit nonsense and associated uncertainty, in your place I would opt for Austria.

I suggest you check the definition of monogram: you should then be in a position to answer your own question.

The Open University have an MA in Music that's entirely online, but it's going to be withdrawn in a couple of years' time and the last chance to sign up for it is 20th September this year:

By my calculation, 75% in the dissertation would give you a Distinction overall, 45% would give you a Merit and 15% would give you a Pass. It seems silly to walk away with a Diploma and have to give £5000 back for the sake of scoring 15% in the dissertation.

It's 72 altogether.

For an international conference I attended last year, they specified that abstracts be one side of A4 at most. I've just checked the book of abstracts and the shortest was two and a half lines. Several others were between four and six lines and some filled the whole page. I'm sure your 220 words is sufficient.
