GITI translates very directly to familiar old quasi-graphic tab form, but it brings a more appreciable structure with the modularity of act, pitch, and time. Basic defaults to the previous sound's (a special, ‘carry-on’, default (with the ultimate default being the last annotation tempo fractional note)), and extra defaults to none (so the extra is not carried-on: it must always be explicitly stated). :2Ī sound (including continuations and rests) can omit its time entirely, or either of its main two parts. Continuation sounds are merely a shorthand for a tied note, and have a ‘ &’ and time, instead of act and pitch: &:2Īnd Rests have a ‘. There are two special sound forms: Continuation and Rest. - – (suffix) continue to next sound – left side of a tie.* or -8 – (suffix) extend by dot, or number fraction (repeatable).- – (prefix) continue from previous sound – right side of a tie.4 – number: lower part of the fraction of bar length, with three optional augmentations:.The following sections will explain the details. The format also allows degrees of simplification: omitting chords, ornament, articulation (second line), and time, down to only pitch (third line): 63=55:2 45 54r1:2**e s:54/10:8sĪnd GITI can also be rendered back into tab-form including all its extras (actuation above, time below): # Black Sabbath ‘Black Sabbath’, main giti:e-4.1 tuning:std tempo:3.603 In GITI it is (note first how the 3, 5, 4 fret-numbers are prepended with their string-number): # Black Sabbath ‘Black Sabbath’, main giti:e-4.1 tuning:std tempo:3.603 Sounds and indicators are blank-separated tokens, and annotations and comments are special lines.Īs a brief overview, consider this ordinary tab: Black Sabbath ‘Black Sabbath’, main riff The former might be an easy addition, but the latter would need more design and adjustment.Ī whole Piece is a string of Sounds, Indicators, Annotations, and Comments. This version does not cover vibrato-bridge use or complex parallelism. But it can also be rendered in familiar quasi-graphic tab form. GITI follows the specialisation of tabs but flattens them into a more manipulable word-like form, and redeems the larger shortfall by adding a traditional kind of time information – all somewhat inspired by the event-packet basic form of MIDI. Guitar tabs are better focused, but with obvious weaknesses and still awkward to read automatically and write manually. Traditional musical notation is powerful and general, but rather mechanically complex and demanding (despite its aesthetic recompense). The format is in ASCII text (so also UTF-8). GITI is concise, expressive, and usable by both humans and software. This is a description/specification of GITI (variant E) – Guitar Instrument Text Interface (electric) – version 4.1: an electric guitar music notation text format.
