Manage scales, chords and arpeggios according to the modern guitar theory GuitarLayers enables you to visualize and manage common or custom scales, chords or arpeggios, on the guitar fretboard. You can, for instance, modify any single note of a common chord or build custom scale or chords note-by-note. GuitarLayers allows you to generate Scales Modes, Chord Inversions, Drop Voicings and Equivalent Chords names, according to modern guitar theories. Create shapes automatically By applying guitarLayers Fretboard Constraints you can shape chords, scales or arpeggios on the fretboard by using a systematic approach. As a result you can generate Vertical shapes, Custom Notes-Per-String shapes, CAGED shapes, String Sets selections. So, do not waste your time by building shapes note-by-note but create them automatically with the speed of a click! Visualize Harmony with Layers As stated by the best guitarists, putting shapes in mutual relation on the fretboard is the key factor to visualize harmonic concepts. By using Layers you can overlap chords, scales or arpeggios in order to visualize them in a given fretboard portion. Moreover you can move the overlapped shapes together, in another position, automatically, with a single click. For instance you can overlap two scales, in order to see notes they have in common or not. Even more you can build automatically useful and beautiful chord-scale or scale-arpeggio colored diagrams. Harmonize Scales Automatically GuitarLayers allows you to harmonize automatically a given scale. Build chords or arpeggios by picking notes from a scale and then propagate them along each scale degree. In addition, the most brave and advanced users can also harmonize scales with custom chords or arpeggios and their related drop voicings and inversions. Print and export your diagrams as images
