Now the most important question - has relating the sounds to colors actually helped any members on this site improve their musical ear ?

I've always considered myself not to have a 'natural ear' - yes I know it can be developed, but when you meet someone who actually has one, you know what I'm talking about - it seems that the same level of ear training and practice has resulted in much more progress on their side than yours.

In my case, I can hear the difference between two chords played on the same instrument one after the other - but in 'isolation' - I can't tell the chord quality. Also, in a song - where there are multiple instruments and melody notes, quite often I can't here the chord quality.

Has anyone else had this particular 'big challenge' in their music education ?
