Chord Library review
A free web reference with reverse chord lookup, progression tools, playback, and optional PDF guides.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Chord Library is a web-based reference for guitarists and ukulele players who need to find, compare, and hear chord shapes. Its core tools cover interactive diagrams, finger positions, scales, fretboard exploration, alternate voicings, difficulty filters, chord identification from entered fretboard notes, and audio playback. Account-based saving lets users keep chords and progressions, while the tuner supports alternate tunings.
The core reference service is free, making it suitable for learners and players who want searchable chord information without a subscription. The paid offerings are one-time downloadable references: Complete Guitar Chord & Scale Reference costs $9 and adds a printable PDF reference, alternate voicings and fingerings, and lifetime access. Complete Ukulele Chord & Scale Reference also costs $9 one time and includes a printable PDF reference, alternate shapes and fingerings, and lifetime access. The plan structure is straightforward for buyers who want an offline-friendly reference document alongside the online tools.
Chord Library’s strongest distinction is the combination of lookup and practice features in one focused service. The progression generator can work with a key and scale while adding tempo, loop, and metronome controls, and the chord and progression playback helps connect diagrams with sound. Printable charts and PDF downloads support reference use beyond the interactive pages. Players looking for guitar or ukulele chord discovery, progression ideas, voicing comparisons, and tuning support should find the scope well aligned. Those seeking broader instrument coverage or a native app should choose a more expansive alternative.
