I am soldering my first keyboard, and are there any specific things I should be aware of that go wrong commonly or any tips in specific.

Practice on old scrap PCBs before jumping onto your keyboard :)

If you've not soldered before, then YouTube. It's very fast and easy once you get into the swing of it.

to get good join, 1st put a bit of tin on your tip (not much, just to make good thermal contact) then apply the soldering iron to the join you want to solder and then put solder in that same join but if possible not on the iron, but near it.
but yeah practice makes perfect, depending on how comfortable you feel with soldering you can either 1st get a scrap piece of electronic or a few cheap kits off e-bay. some of them are 1$ and easy to solder and make for fun toys after the fact as well.
get yourself into a spot with good light and decent ventilation.
if you do not have one already getting a temperature controlled iron will make your life much easier, as is finding the right tip for you (i like slanted, others like conical or flat, to each their own) i usually recommend hakko 936 clones for amateurs such as myself but other options are available and valid.
and it also depend on the keyboard, if you fell like it is for you a cheap pcb and do not mind scraping it and likely some switches in the name of learning then you can also go and solder that directly, keyboard switches are not hard to solder at all, and de-soldering is where most problems arise.

All good advice. I went over the whole process I find works well here. I think that includes desoldering, so you can ignore that part unless you make a mistake and/or change your mind on anything.

There's a lot of good posts in this recent thread as well.

I'd recommend to watch some videos, e.g., Youtube, and see how it is done.
Then there are some good electronics websites, e.g., Sparkfun is good, here is one of their tutorials:

There you see also suggested readings if you want to venture into pcbs etc.

This page is also good, I searched on it and here is another guide, doesn't seem to be as extensive though,

Also some recommended equipment:

This is the Geekhack soldering bonanza thread:

Full of good info. Many years old, but soldering is not exactly what you would call a rapidly evolving technology.

You will have more success I think with a temperature controlled soldering station instead of a pen.  I've had issues with pens getting way too hot or not hot enough.  You may not want to spend $100 - $120 on a Hakko or Weller station (well worth it in my opinion), there are plenty of Chinese alternatives available for around 20-45 dollars.  A good tip is also important and if the station does not come with a quality tip with the right shape they can be purchased.

Leopold FC660M- my new favorite, right out of the box.

In my job, I've done a lot of soldering and the most important thing I've felt is flux.

If you have the correct and identical environment, the presence or absence of a flux is the most important factor in determining the quality and difficulty of soldering.

If you aren't skilled and quick work is not possible, the flux will be insufficient. Don't forget to buy the flux.
