Not much new qualitative progress to report since a month ago. I'm getting a little better at the songs I've been practicing. The jump to Fmajor from an arbitrary chord is getting almost fast enough that I can reliably use it in decent-tempo songs. I've been able to get it easily fast enough like 25% of the time for quite a while now; it's the approach to doing it much closer to 100% that is taking all the work now.
Melodically, I suppose I am actually considerably more capable of alternating i-m plucking with the right hand, and a little more agile with the left on a couple of blues scales (I've been practicing minor pentatonic plus the #11, root on string six or five)
