In my many attempts to study and learn a musical instrument: trombone, piano and guitar all were less than successful. I ever mastered the skill of reading musical notes and relating them to the instrument and sound.
And so, after coming across this image of a keyboard with colored keys, I wondered what if music instruction was designed with additional visual supports like color associations between the page and the instrument would I had a better chance of getting it?
Oh well, I will leave this opportunity for someone to research and develop if it hasn't been done already. The one thing I know is that it would help those like myself whose ears aren't as useful as our eyes?
