What Twelve Assistant Tab Editor is
Twelve Assistant Tab Editor is a web application for creating, editing, playing, and sharing guitar tablatures by placing notes on a fretboard. Notes retain their intervals in the active scale, so the scale can change while the tab remains. The editor accepts melodic notes and chords that stack notes across strings. Rhythm may show durations, stems, beams, rests, and automatic bars, or stay hidden for a simpler sequence. Users can adjust beat duration, effects, fingering, or delete beats; listed effects include bends, vibrato, hammer-ons, pull-offs, and slides. Playback follows rhythm and rests at an adjustable tempo. Named tabs can be created, renamed, duplicated, and deleted with automatic saving. Tabs can 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. A free limited trial is available, while listed plans include Guitar, Harmony, Trainer, Premium, and lifetime access.
