Its Marc from LightKey Piano. Not being a vocalist, I play solo piano and usually incorporate the melody on the fly when reading a score. I realized however that I did not always play songs the same way and while its good to improvise I never really ended up with performance pieces.
So several months ago I started to arrange solo piano scores for Oasis and Coldplay songs. The scores became videos and the videos became YouTube tutorials (Or song guides is a more accurate term).
There are currently over 100 videos that are available if anyone finds them useful. Although you can learn the songs with the videos, they are intended as compliments to traditional sheet music and help to visualize finger patterns and harmonic tempo for any sections you are finding tricky.
You can find the videos on LightKey Piano YouTube Channel - LightKey Piano
