SweepShapes is a guitar fretboard visualizer for exploring sweep-picking patterns, arpeggios, suspended chords, and modal shapes on a realistic 24-fret electric guitar neck.
Visualize sweep patterns, modal positions, chord tones, and compact arpeggio shapes. Choose a scale family or chord family, root note, mode (or chord quality), tonic string, and fret position to instantly generate playable shapes for practice, improvisation, and composition.
Explore smooth musical movement with intelligent darker/brighter modal transitions based on note-pool continuity and modal brightness. At the edges of a modal family, SweepShapes can suggest related parent scales that differ by only one semitone, helping you discover natural harmonic progressions and fresh musical ideas.
Save your favourite shapes into Projects, replay them individually or as complete sequences, and generate inspiring progressions that travel through nearby modal targets before resolving back to the starting shape.
