Why guitarists can't read music (and the ten-minute fix)
The guitar hands you three ways to dodge standard notation. Here is why that happens, and a ten-minute daily routine that actually starts to fix it.

Real-time pitch detection on a laptop mic: what actually works
A build note on detecting the note you just played from a laptop mic in the browser — why FFT peak-picking disappoints, what autocorrelation fixes, and where "good enough" lives.
Theory
Borrowed chords: minor colors in a major key
How the parallel minor lends a major key four darker chords — iv, ♭VI, ♭VII and ♭III — what each one does emotionally, and the songs that lean on them.
