Alright. Here is a basic tutorial on how to read / play written music (made by someone with around a decade of piano experience)

The first step is to know what keys are what. Here is a basic picture showing you which key to press to get a certain sound

Next, you're going to want to know what clef you are playing in. There are 2 Clefs. Treble Clef, and Bass Clef. The notes for each clef are written differently. You may be asking "Why is it like this?" I don't know, to torture people.

The way to find the clef is to look on the right and look for either the G looking thing or the little frowny face. Below are two pictures showing you which is which.

Now that you know what clef you are in, you are going to want to know the key signature you are in. Basically what this determines is what black keys you will need to press, as those keys are known as sharps / flats. Sharps look like '#', and Flats look like a 'b'.

Here is a little list  of what each thing means.

Sharps:

Personally, I would first learn to read songs in the C major (A minor for bass clef) key signature. It is the easiest for piano, as there are no sharps / flats. So you can just stay on all of the white keys, instead of having to move your hand to uncomfortable positions. Learn to read music before getting into harder stuff ya know.

Okay, now we are going to learn the notes for each clef.

Treble Clef:



In my opinion, Treble Clef is the easier of the two to read music. Most songs that I've played are written in it, and it's normally the first clef anybody gets accustomed to. Saying this, Here is a picture of all of the notes inside of the Treble Clef bars.

The bottom C is known as "Middle C". Which means that it is the C that is in the middle of your keyboard. Usually sounds like this.

Now that you have a starting point, you have to memorize where those notes are. Refer back to the chart to look at the notes as you try playing them.

Some little shortcuts to quickly read the spaces / lines are to use phrases that have words that start with the letter of the note that I am playing. For example, the notes in the spaces spell out "FACE", and the notes in the lines are EGBDF. I normally use "Face" for the spaces, and "Every Good Boy Deserves Fudge" for the lines. You can always make up your own version of what to say, but it's something every musician uses.




Bass Clef:



Bass Clef is similar to Trebel Clef, the only difference is the way the notes are placed.

as you can see, Bass Clef has "Middle C" on top, which means that the song you are playing is going to be below Middle C. (duh)

There are also shortcuts to know the spaces (ACEG) and the lines (GBDFA). The ones I use are "All Cows Eat Grass" and "Good Boys Deserve Fudge Always."


I think that's pretty much it. Another thing to learn are scales. The best way to learn is by hearing / watching, so I am just gonna link a video.

And that's pretty much the basics! Hope it doesn't seem like too much, and I hope you get at least a little bit out of it!
