Hello from Kent!
Here is a potentially very helpful video (at bottom) that features real-time playback of the Sheet Music sold below: Beethoven’s Moonlight Sonata, Entire First Movement – Sheet Music with Letters & Notes together (PDF).
The product link above has all the details you need about this sheet music for download. In a nutshell, this is the complete First Movement of Ludwig v. Beethoven’s Piano Sonata No. 14 (famously known as ‘Moonlight Sonata,’ originally when referring to the First Movement’s popular nickname).
This video can be useful as a reference when making sure you have your bearings in the sheet music. When you scroll through it, you can tell what page and measure is being highlighted and played at any spot, by looking in the little preview square (as you move the play head around). YOU CAN ALSO SLOW THIS VIDEO DOWN, using YouTube’s playback settings for the video – just click on the gear icon in the lower right of the player window.
There is also a Keyboard Video graphic, just below the sheet music view, that highlights and sounds every note being played from the highlighted sheet music, in sync with the sheet music audio, in real time.
