ModusCycler — Modes & Jamming

Kliimba

About this app

Turn chord progressions into music you understand. ModusCycler shows you the matching church modes and scales for any progression — on fretboard, TABs, piano and standard notation — and backs you up with a complete jam band.

🎸 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.
★ Launch offer: everyone who joins in the first 6 weeks keeps the Jam Session Builder free forever — afterwards it is a €19.99 in-app purchase.

🎓 SCALES FOR IMPROVISATION TUTOR
The Modes Explorer derives church modes step by step on the fretboard: choose a position, understand the mode, play the scale. 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, xylophone, vibraphone, accordion, harmonica or voice. Fingering diagrams cover guitar and piano; the scale theory applies to all.
