Repertoire decays: gig prep as memory management
Songs are skills with a shelf life, not entries in a list. Treating your repertoire like spaced-repetition material — reviewing each tune just before it fades — beats cramming the week of the gig.

Edgars: a practice butler, and the rules it will not break
Edgars answers the question every practice starts with — what should I play next? — in about three seconds, and it makes every answer honest. A build note on the loop, the two ratings, and the six design constraints behind the app.
Theory
The four-chord loop: I–V–vi–IV
I–V–vi–IV is the most-used pop progression of the last sixty years — Let It Be, No Woman No Cry, With or Without You. Here is why it works and why the progression was never the song.
Software
What should I play next?
The first three minutes of practice are a negotiation, and the negotiation is where sessions go to die. The fix is deciding once, with a published rule: gig urgency first, then the weakest scores, ties broken by age.
Theory
The rock cadence: I–♭VII–IV
Three major chords borrowed from outside the key — I, ♭VII, and IV — are the engine of rock harmony. Here is why the flat seven works, why it never resolves, and how to make it groove.
Practice
The journal that writes itself
Every teacher says keep a practice journal; almost nobody does, because journaling is admin at the moment you least want admin. The fix is not discipline — it is letting the session leave a trace on its own.
Theory
The turnaround: I–vi–ii–V and rhythm changes
The I–vi–ii–V turnaround is the second most-played progression in jazz, and its full form — rhythm changes — is the template behind dozens of standards. Here is why the vi chord becomes dominant, and how the Tadd Dameron substitution rewrites the bass line.
