A Bach Polonaise! Please use turbo mode (shift + green flag). Press space to start the music. Use the arrows on the screen to change the tempo and key (in halfsteps). Enjoy the music! :-) I enjoy the key at -5 I think.
This is from the notebook for Anna Magdalena Bach, so we don't know who it is by. However, it is likely that one of Anna Magdalena Bach's relative's composition. I never learned this one, but then one day I heard it, so I decided to share it. It's nice and simple so I enjoyed making it on Scratch. I hope my presentation of it is nice and simple too :-) (You may notice that one of the arrows does not fit in...)
