You enter any typical jazz chord chart into the JSSS program or use the Band-in-a-Box file import utility. Next click the 'SUGGEST JAZZ SCALES' button. The JSSS program will analyze your chord changes using artificial intelligence techniques and suggest commonly used scales for your solos. You can click the '?' button for each scale and the JSSS program will explain its suggestion. Shows how you can view a cluster of chords with a minimum of improvising scales, enabling you to quickly learn to play through the changes. Your entire jazz chord chart is evaluated, not just single chords in isolation. The program explains relationships amongst the scales, such as how one scale leads into another.
