Will my degree be recognised?
You should have absolutely no problem with recognition of a music degree from a good university or conservatoire. If you are satisfied with the overall quality of the university, the reputation of its music department then it is unlikely that you will ever be at a disadvantage if you study music abroad. All degrees within the European Union should be viewed equally although it is always a good idea to investigate the reputation of your chosen university.
Does it make sense to study music abroad?
Music degrees abroad may offer you considerably different facilities and study opportunities. As UK universities face cutbacks in their funding for the arts you may find that international music education offers excellent value for money.
As the best place to study music is often determined by the quality and reputation of the teachers, it may make perfect sense to study abroad. However, this could also be a reason why you would decide to stay in the UK.
What else should I bear in mind?
There are a number of conservatoires in Europe that teach entirely in English. However there are also universities that may be able to offer you a musical education in English even though the degree is notionally in another language.
As far as we know there are no music technology-equivalent degrees in Europe taught in English. There are some degrees that focus on music teaching.
Where should I look for music degrees abroad?
The Netherlands has a number of excellent conservatoires that teach in English, for example at Hanze University of Applied Sciences and at Zuyd University of Applied Sciences. There are options in Belgium, Hungary and Estonia. Music schools in Australia and the USA could also be viable alternatives.
