Take from one who had all the great musicians around him, Butch Heyward, Timonthy Wright, Twinkie Clark, Willard Meeks, Carlton Pope...etc. I didn't have the opporunity to sit down with any of them but I developed my ear for music just to hear what they were doing. Yes, it took time but, when I learned it I stored it away and made room for all the musicians I heard on the albums ( no CD's then). Now I can learn any song from any musician. Since 1989 I've been willing to assist other musicians so that the won't go through what I did. The organ is a beautiful instrument and when you learn to make it sing....wow......watch what happens in your service.
