Reference Pages
Nine pages, five working tools.
Odd Meter and Cycle Calculator
Bar lengths in seconds at any tempo and meter, subdivision timings, and where two different groupings come back into line.

Craft · Ledger + PlayerOdd Time Signatures Explained
5/4, 7/8, 9/8, 11/8, and the polymeter-vs-polyrhythm distinction people actually mix up — with a real accent-pattern player you can hear.
Craft · Ledger + WorkbenchHow a Riff Is Built
Sequence, inversion, retrograde, augmentation and fragmentation applied to heavy riffs, plus pedal points and chromatic tension — with a working transformation workbench.

Craft · ExplainerBlast Beats Explained
What a blast beat actually is, its main variants, where the technique came from, and how to program one that doesn’t sound like a machine gun.
Craft · ExplainerPalm Muting and the Chug
How palm muting actually works, why it produces the chug, hand placement and pressure, and what a tight low string means for the mix.
Craft · ExplainerPinch Harmonics and Tremolo Picking, Explained
Two guitar techniques that sound nothing alike but share one mechanic: fast, precise contact with the string. How each actually works.
Craft · ExplainerThe Breakdown
What makes a breakdown land: the stripped-down riff, the tempo pull-back, and the songwriting logic behind heavy music’s most physical moment.
Craft · ExplainerWhich Engine Does This Band Run?
Twenty-seven bands and nine concepts, each reduced to the one problem it solves — so bands that share no genre can be compared on what they actually do.
