Stop memorizing shapes you don't understand. redLUX shows you why the notes sound the way they do, then helps you turn that into music.
A studio-accurate tuner, a chord and scale library, an interactive fretboard trainer, a jam station and a songwriting studio in one app. Everything a guitarist needs, without juggling five subscriptions.
SEE THE NOTES THAT MATTER
Most scale apps show a wall of identical dots. redLUX builds on the pentatonic boxes you already know (circles), then adds triangles to mark the note that gives each scale its character. The #4 that makes Lydian sound like Lydian. The b2 behind the darkness of Phrygian.
· Bridge basic patterns and modal theory, and know which note to lean on
· Shapes, not colours, so it stays readable in sunlight and for colour blind players
· Understand why a note creates tension or release
LEARN THE WHOLE NECK, NOT JUST SHAPES
· CAGED View: see one chord in five places and the single finger move that turns each shape into its extensions
· Triads Interactive: every three note shape on every string set, with voice leading that shows the shortest move between chords
· Layers Mode: put a chord on top of the scale and step through a progression, watching the chord tones move under your fingers
· Double tap any chart to open it full screen, then swipe through every voicing, inversion and string set
CHORDS, TRIADS AND VOICINGS
