You have probably heard me dribble on about scales during Sunday chats and such. But it can be intimidating. Let's not make it so. Start with the Majors, including the accidental keys. This chart is handy to keep in front of you until you have it down.
Charts like this have speeded me up tremendously. When you get this one down, I have one for the minor keys as well.
Keep a Song in Your Heart,
