Castle theme from Super Mario World (SNES) on the keyboard. Best viewed fullscreen, in high resolution and with earphones on. This was requested by MetroByte here on TH-cam and by Jose Ortiz on my Facebook page.
Before you say anything, yes, I cheated on the fast parts, recording them twice slower and speeding them up again while editing. This is especially true of the synth strings, which I split in two parts, recording every other note separately!
Some tracks may be a little off sync, and my fingering is not exactly perfect, but at least the notes are right - I hope. This is not intended as a didactic tutorial. I realize not all notes can be seen clearly, but if you have some experience on the piano, it should be enough to get started on the song.
The footage is of myself actually recording each track individually as you hear them, and the audio is the final result put together by the keyboard with no mixing, except for volume adjustments and echo. Recorded on a CTK-6000. Based on the MIDI files uploaded to vgmusic.com by users King Meteor and Erik.
Time signature 4/4, tempo 104 for the first part and 128 for the second, key C minor
