Turn chord progressions into music you understand. ModusCycler shows you the matching church modes and scales for any progression — guitar modes on fretboard and TABs, plus piano and standard notation — and backs you up with a complete jam band.
NEW: EXTENDED AND ALTERED CHORDS
Type "Cmaj7, Fm7, G7#5" or pick from the wheel: 29 chord types, from ø and dim7 to 7b9, 7#9 and 7alt — for jazz, neo-soul and fusion. Matching scales include Lydian Dominant, Altered and Whole Tone; a switch adds pro scales from harmonic and melodic minor.
JAM SESSION BUILDER
Build your own backing track in seconds: tap chords into the bar grid, get piano accompaniment with musical embellishments (a statistical improviser based on Chopin and Beethoven statistics), plus a precise metronome with swing — hit Play and jam. A fresh session sounds finished right away: cello bass and piano come preloaded.
The Jam Session Builder is currently included in the purchase price.
MODAL INTERCHANGE & CIRCLE OF FIFTHS
The modal interchange table shows borrowed chords from every parallel mode — one tap places them in your progression. The circle of fifths highlights your mode chords (degrees I–vii°) and the most important modal interchange chords in colour. The stability check tells you whether your mode really holds — or collapses into the relative major.
ESCALATOR — SCALE REFERENCE & SLIDES
All seven positions of the major scale as a printable Kiltz/CAGED and 3NPS reference, right inside the app. The transitions trainer connects positions with slides — and the out-of-scale slides reveal the pros' trick: change the entire scale family with ONE shape, using a slide formula like "C, 2 frets down and back". You always land on a chord tone, fingering included.
CHEATING CHEAT SHEET WITH SCALE-CHANGE COMBOS
Two linked wheels per chord: church mode and scale in shorthand. Below, every mode combination of your progression sorted by effort: no change, one change (there and back) or two — each with its slide formula. Pin chords to keep them fixed; the eScalator opens right with the matching keys.
SCALES FOR IMPROVISATION TUTOR
The modes·explorer derives church modes step by step on the fretboard — with Kiltz/CAGED boxes and all seven 3-notes-per-string patterns.
FOR EVERY MELODIC INSTRUMENT
ModusCycler shows you which notes fit over the chords — in standard notation and by note name, playable on any instrument. Ideal for improvising and melodic accompaniment on saxophone, clarinet, flute, trumpet, violin, accordion, harmonica or voice. Fingering diagrams cover guitar and piano; the scale theory applies to all.
