Finally, a fretboard that needs no mental transposition
Many music theory resources are designed only for right-handed players. For a left-handed guitarist, this often requires mentally flipping each position before even starting to practice. Twelve Assistant lets you display the fretboard in the adapted orientation, so visual reading matches your actual playing gesture.
Left-handed mode does more than just flip an image. Fret markers, notes, intervals, scale positions and diagrams maintain their musical logic. You can hear notes, isolate a fretboard zone, compare multiple views and send your elements to the Desk.
Once you set your preference in your profile, it stays. Compatible fretboard displays and diagrams automatically open in the right orientation. This saves you from resetting every session or tool change.
Your entire musical environment in left-handed mode
Mirrored fretboard
The nut, frets and positions are shown in the natural orientation of a left-handed guitar.
Scales and modes
Spot notes, intervals and playing zones across the full length of the fretboard.
Chord diagrams
View shapes and voicings without having to mentally flip the diagram.
Persistent preference
Your right-handed or left-handed choice is saved in your user preferences.
All your tunings
Left-handed mode works with preset and custom tunings.
Personal desk
Gather your diagrams, analyses and exercises in a workspace.
From visualization to composition
Choose a scale, mode or chord and immediately see its distribution on the fretboard. You can display note names or intervals, hide unnecessary information, limit the working zone and hear the elements. Reading becomes direct, including for preparing a lesson, rehearsal or improvisation.
The progression tools then help you build a chord sequence and explore available voicings. The result can be organized in the Desk, printed or saved with your other working elements. Left-handed mode supports a real practice workflow, not just an isolated image.
Advanced features around your tuning

Personal desk

Display everything left-handed
The number of strings and tuning are independent of orientation. You can keep exactly the same musical configuration and display the fretboard in the orientation matching a left-handed instrument.
When the left-handed preference is saved in your profile, compatible fretboard displays and diagrams use it automatically. The setting remains editable at any time.
A preference that follows you
Choose right-handed or left-handed once in your preferences. The fretboard keeps the same tuning and adapts only its visual orientation.
This preference then applies to compatible fretboard displays and diagrams.
Set once, work everywhere
Open your user preferences, choose the left-handed display, then select your instrument and tuning. From there, compatible components automatically use this orientation. You can switch back to right-handed mode anytime, without changing your musical data.
