My recordings have mostly been contemporary classical pieces on CDs by performers who play my stuff. My music does not use functional tonal harmony and keys. I've changed my tune for now. I'm planning to make a collection of 5-6 blues tracks featuring the guitar stylings of me, Blind Lemon Fritts (for real, this was my name in junior high). I'm idly curious to know how people, particularly in blues, sequence their tracks in terms of key structure. When gigging, as far as I can recall (I played blues, rock,country, and jazz gigs), we tried to separate minor songs from each other and songs in the same key in a row. Definitely not a hard and fast rule, as I've played several songs in the same key before (this can especially happen if you take requests). But I'm talking something like an EP for SoundCloud. I am considering three particular songs in G. There will be 1-2 minors, and something in E, A, or D. I'll be mixing up the styles a little bit (but still blues), and will swap out guitars and maybe amps. I hear a lot of non-classical recordings (blues, 60s rock) that have 2 or more consecutive tracks in the same key. Easy enough to look that up, I guess. What should I do? Endeavor with extreme prejudice to avoid placing two G majors next to each other? Or should I lightly endeavor to avoid this? Just having fun, think out loud and writing it down. Haven't done this here in a while, as there had been more of a tendency for members to start arguing about unrelated things. Or they go meta, which is worse of all (why ya doing blues? why don't ya sing? do you have a van?).
