This is the third in a series of articles entitled “Which Scales Go with Which Chords?” covering the Minor 7 Chords.
When improvising, it’s important to know which scale(s) to use. Traditional music usually has one scale for the entire song (or section). When the song modulates (changes key), the scales used are also changed.
