Charts for beginners
A beginner's problem is rarely a shortage of explanation. It is that what was explained last week has to be recalled this week, in the middle of doing something else, and it is not there yet. A sheet on the wall covers exactly that gap — and then quietly stops being needed, which is the point.
Most of what is here is for instruments: the first chords on guitar and ukulele, the notes along the fretboard, the layout of the piano keyboard, note values, intervals, the pentatonic box, and the alternate tunings worth meeting early. The rest is for people starting to write code — the flexbox properties, and where a change sits in Git.
Hang them where the practising happens. A reference that makes you put the instrument down has already failed.
