Training Sheets
Pick a style. Each sheet inside a genre is a self-contained practice unit with chord voicings, triad inversions, scale maps, and the signature tricks that bring the style to life.
Blues
12 sheets →12-bar forms across the blues lineage — Delta, Texas, Chicago, soul-blues, slow blues, neo-soul. Triad work, pocket pairing, and scale targets all in one place.
Bluegrass
1 sheet →Flatpicking and cross-picking in the Tony Rice / Norman Blake / Doc Watson lineage. Chord shapes drive the solos — each card shows multiple voicings, the picking pattern with an animated playhead, and the melody trace overlaid on the chord.
Folk
1 sheet →Traditional Appalachian and folk repertoire — ballads, modal tunes, and Doc Watson-style flatpicked instrumentals. Same chord-shape-driven approach as bluegrass.
Jazz / Soul
4 sheets →Foundational harmonic moves — cycle-of-4ths, neo-soul vamps, dorian i–IV, ii–V–I. Drilled with chord shapes, comping rhythms, and upper-structure embellishments that produce the Rhodes-piano old-soul sound. Intentional flat-key choices to pull in Cm, Gm, and other minor chords usually missing from guitar repertoire.
Tres Cubano
16 sheets →Chord progressions for popular Cuban tres repertoire — son, guajira, bolero, cha-cha-chá. Standard Renesito Avich tuning (G–C–E, with the G course in octaves).
