The first part of my series on the skills that make you the sort of person people want to make music with talked about being on time. This second part leads on from that, and can be summed up simply as 'be there'.
Even worse than being late is just not turning up without letting anyone know. If you say you're going to do something, do it. If you later find you can't do it, then let people know as soon as you can, and if you not being there is going to cause a problem, offer a solution if you possibly can, such as finding someone else to replace ('dep' for) you at a rehearsal. As with normally being on time, if you're normally dependable, people understand that you might occasionally need to be absent through illness, an unexpected situation at home, an occasional accidental double-booking, or something else that comes up where you need to make a decision whether to attend. Even nice things, like a holiday that means you miss one of the weekly rehearsals you go to, are not generally a problem if you let people know well in advance. If you regularly agree to do things and then don't turn up, that is a certain recipe for not being asked back, asked to do other things or recommended to other people.
The thing is that rehearsals are not just about learning your part - in fact, that's what practising at home is for. They're about learning to play together as a group, and how the piece works as a whole. They're about finding out how your conductor/ group specifically wants to play that piece and for all the little bits of information that you pick up along the way. They're about getting help with those bits that you can't quite figure out on your own. Even if you can play it all easily, the other people around you also need to get used to playing with you and hearing how it sounds as a whole.
I think there are two things that help you do manage to 'turn up' - the first is keeping a diary. 'Keeping' a diary as in actually writing in it (or using an electronic one). Put appointments in as soon as you can - I generally put everything in my Google calendar immediately, then sit down once a week or so to update my paper diary. Whatever works for you, but don't rely on scraps of paper or your memory. However good your memory is, writing it down helps to reinforce it, and it gives you space in your brain to think about more important things like what to have for tea. Of course, if you put appointments in a diary, you do then need to remember to look at it, so get into a pattern of checking it regularly. If it's an electronic one you can usually set it to remind you of things too, so if you're likely to forget to check it, you can get it to beep at you and tell you to go to rehearsal in two hours' time. The time it takes to set all this up is worth the time - and hassle - it saves later.
The second thing is not over-committing yourself. Musicians (especially when they're training/ at university etc) are often told that they need to say 'yes' to everything - don't turn down an opportunity. You might never get the chance again! Or they get swept away with enthusiasm and want to do EVERYTHING. The trouble with that is that you can end up too busy, things start to clash with each other, and you get so worn out that you can't manage to do any of them well. It is tricky to get the right balance for and work out what to prioritise, and I fear that perhaps you do have to reach the point of doing too much before you realise that you need to let some things go. If you start to find yourself feeling over-stretched and letting people down because you've got too much happening, then you probably need to scale (musical pun not intended, but since it's there I'll leave it in) it back a bit.
However, people do and will understand, and generally respect other people's decisions to prioritise one thing over another, whether that's a one-off or in the long term. They might be disappointed if you don't choose or stop coming to their 'thing' but if they get huffy/ rude about it, I'd suggest that maybe you don't want to work with them anyway. They don't need to know all the details and it's fine to turn down an offer with a simple "I've got a prior commitment that day, but would be interested if you need someone again in future". If you can recommend someone else who might be able to do it instead, that's even better and often much appreciated.
Yes, sometimes the decisions are difficult. You might not get the chance to do exactly the same thing again, but actually, I'm not sure that many 'opportunities' are so life-changing that it'll drastically damage your musical career (whatever that means to you) by not taking them. On the other hand, being known as a person who reliably turns up is definitely a good thing.
