What to do, what to do with these 3x A minor tracks - two of the 12 bar blues...how about some new licks or a change of scale(s)?
3 easy licks - pretty well laid out from Musicradar
From a surprisingly useful post on StackeExchange of all places...
In short: you can play an A min blues scale over the entire song if you want, but it certainly isn't wrong to stray from A min when playing over the minor blues.
On the iv chord, some of the most common alternatives would be the D dorian minor scale or the D minor blues scale. You might also hear a D melodic minor scale used.
On the v chord, some popular choices are the E natural minor (also known as E aeolian minor, which contains a C) and the E minor blues scale. Another option would be to play E phrygian, which can lead nicely to A natural minor. Alternatively, you can treat the Em7 chord as an E7alt chord (make a chord substitution) and play E altered scale or an E phrygian dominant scale:
And, don't forget Evo's face ripper of a thread - the over-simplified tl:dr version of it is - plan your solo, break it down into chunks based on the underlying chords and then string it together into an expression that communicates something.
Happy jammin peeps!
