IGDb began with guitar lessons, photographs and diagrams made by Hodaka Hashi. The site also uses work shared by open-source contributors.
Tools in this site
- Astro builds the pages. Its MIT licence is included.
- alphaTab renders notation and tablature and provides interactive playback. See its licence and asset notices.
- Pagefind provides site search. Its MIT licence is included.
- The tuner uses pitch-detection code from Felix Gnass’s open-source tuner, with its MIT licence.
The static scores include a subset of the Bravura notation font, renamed IGDb Notation Symbols. Some teaching diagrams also use Bravura glyph outlines. The SIL Open Font License and copyright notices accompany the font. Synthesised playback uses the included SONiVOX SoundFont; its notices and Apache licence are linked from the alphaTab notice.
Earlier versions
Previous versions used Foundation, Font Awesome, Icons8, Wimpy Player, Sergi Mansilla’s guitar-chord work and Chris Wilson’s metronome work. We retain this acknowledgement of their contribution to the site’s history. Original chord-library positions have been preserved in the reference catalogue.
