I've been teaching piano for almost 20 years now, and I've noticed with adults who want to learn piano that the thought of learning to read sheet music can be pretty daunting.
I made a video that pretty much explains why we write music the way we do, and the simplest way to go about learning it and finding the notes on a piano or keyboard. This really is geared toward adults who know very little or had only a little bit of note reading when they were young and want to restart.
Due to the length (I had a LOT of info to cover!), I do have times for where certain topics are discussed below. If you watch it on Youtube, you can click on the timestamps in the description and it will take you directly there, otherwise you can just fast forward to those spots if you want to skip over some of the basics at the beginning.
