Although I believe there is a limit to value of practicing and understanding chord scale theory, the melodic minor scale is so prevalent in jazz improvisation and composition, I think that it’s important and relevant for the developing improviser to learn these modes in all keys.

You can play along with or sing along to the mp3 for ear training and to help you hear if and when you are making a mistake in a scale or mode
