Tuning down a half step

Most music that we listen to have guitars' that basically the same as far as tuning.

These are the six open notes in standard tuning. There will come a day, if you stay with playing, that you will encounter a change in tuning. Not very many artists, of any level of experience, will write songs in a different tuning because it is hard to match words after that. Anyways, as long as you know the Major Scale pattern (W-W-H-W-W-W-H) and that sharps and flats don't go between b/c or e/f then each string should be fairly easy to tune.
Ex. Tuning down 1/2 step would look like this:

A#------------------
