Twelve Assistant Tab Editor
Paris, France
What it is
Twelve Assistant Tab Editor is a web tool for creating, editing, playing, and sharing guitar tablatures. Users place melodic notes or chords on a fretboard, while each note keeps its interval in the active scale. Scales can be changed without starting over. Rhythm may show durations, stems, beams, rests, and automatically handled bars, or remain hidden for a simpler sequence. Editing includes beat duration, fingering, deletion, and effects such as bends, vibrato, hammer-ons, pull-offs, and slides. Playback follows the score’s rhythm and rests at an adjustable tempo. Multiple named tabs can be created, renamed, duplicated, and deleted with automatic saving. Tabs may be pinned to a music stand, arranged on a sheet, and printed. Access is through the website on a personal computer with a high-speed internet connection. Guitar and Premium plans include the editor. Plans range from free trials to paid subscriptions, including Premium Unlimited at €9.99 a month.
