What Chord Library is
Chord Library is a web-based reference and toolkit for guitar and ukulele players. Its guitar library lists 192 chords across all 12 keys with interactive diagrams, finger positions, audio playback and difficulty filters. The site also describes more than 180 scales, including major, minor, pentatonic, blues and modes, with fretboard diagrams and diatonic chords. A progression generator lets users choose a root and scale, arrange chords, and use playback, looping, tempo, time signatures and a metronome. The chord identifier names a chord, its notes and its sound from a fretboard shape. A microphone tuner offers a needle display, cents readout, reference tones and alternate tunings such as Drop D and DADGAD. Seven interface languages are listed. Chord and scale pages provide free chart images, while registered users can save chords and progressions. PDF references cost $9, paid once.
