Great stuff and very true what Don says. What Tony M demonstrated is also known as the minor blues scale. I’m embarrassed to say I didn’t understand how to use the other blues scale, known as the major blues until recently. The expert improvisers know how to weave in and out of both the major and minor blues. scale. For more info on this topic I highly recommend Dan Greenblatt’s book “ The Blues Scales, Essential Tools for Jazz Improvisation”
