The theme song from the Cloud Atlas movie, is one of my favorite piano pieces. It starts slow and relaxing but gradually picks up pace. I did some customizations to this version by adding some strings midway (thanks to the Yamaha P-255), and by returning to the slow and relaxing part after the crescendo.
I played this one sing a Yamaha P-255. Audio was recorded separately via the keyboard’s save as audio file feature, and was later added to the video taken by my Olympus OM-D E-M5 Mark II camera. This ensures there is no background noise and the audio you hear is nothing but the music.
