Theory
Harmonic minor: the scale with the gap in it
Harmonic minor is the natural minor scale with a raised seventh. That one change gives minor keys a real dominant chord — and gives the scale its signature gap, the augmented second.
Theory
Triad inversions on string sets
A triad inversion puts the third or the fifth in the bass instead of the root. On a three-string set the three inversions chain up the neck — and chaining them is the drill.
Theory
Mixolydian, practically: the major scale with a flat seven
Mixolydian is the major scale with a lowered seventh — C D E F G A B♭ in C. Here is why that one note makes it the sound of rock, blues, and any chord loop that never quite goes home.
Theory
The Andalusian cadence and other minor moves worth stealing
The Andalusian cadence is four chords walking downhill — i–♭VII–♭VI–V. Here is how each chord works, where you have heard it, and a few more minor-key moves to steal.
Practice
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.
Software
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.
Practice
CAGED, but for arpeggios: five shapes, whole fretboard
The CAGED system maps arpeggios, not just chords — five shapes that tile the whole neck for one chord, how they connect, and a practice order that makes them stick.

Inside Arpèges: designing one-tap practice
A build note on Arpèges — why the whole design bends around getting from a cold start to your first arpeggio rep in a single tap, and what I gave up to protect that.
