March Daily Challenge - Key

Day 3 of MissyMoo's March daily challenge - Key: Take a photo of a key. Be as creative as you can/like.

I've blipped a few door key types of keys in the past, so it was time for a change, whether it was a keystone, the solution to a puzzle, an alignment aid or off to the realms of music which has a number of possibilities.

Time to dust off the trusty keyboard then, and go for the easy option - a keyboard key.
