Oolimo is the interactive foundational reference for guitar chords – a learning and lookup app that explains chords clearly, supports songwriting, and inspires fresh sounds on the guitar. – No subscription! Pay once – use it forever and receive updates. – Current languages (included in every app): English, German, Spanish, French, Italian, Dutch, Danish, Norwegian, Swedish, Portuguese (Brazil), Portuguese (Portugal), Chinese (Simplified), Indonesian, Japanese. Learn guitar chords and chord symbols as used by professional guitarists in modern pop, rock and jazz – including complex jazz chords. Let the Chord Analyzer name chords you've discovered on the guitar and show you how they are built. – Chord Finder, Chord Analyzer and music theory in one app. – Learn and understand chords – Read chord symbols confidently (including complex jazz chords) – Analyze chords instead of guessing – Apply music theory directly on the fretboard Oolimo clears up nonsense chords and incorrectly or confusingly written chord symbols, and explains with clear logic how chord symbols (chord names) are written unambiguously and how to correctly interpret different notations. When musicians from all over the world play together, it's important that everyone speaks and understands the same language – and that the language is easy and clearly understandable. — The Modules — Chord Finder Find musically meaningful chords instead of random guitar shapes. All fingerings come from a hand-curated database of playable voicings and are intelligently transposed by an algorithm. Every chord adapts automatically to the selected key. With a single tap you can send shapes directly to the Analyzer and explore inversions and different interpretations of the chord. Chord Analyzer Enter any guitar chord into the virtual fretboard and instantly get the correct chord name, including inversions. No "unknown chord" messages thanks to the intelligent recognition algorithm – even for complex chords, slash chords and inversions. The Chord Analyzer also supports alternative tunings (open tunings). Chord Progressions Explore and compare the most important chord progressions with an innovative matrix that visualizes harmonic functions and relationships. Practice the most important progressions systematically in different keys and variations – and master them so well that you can rattle them off in rehearsal to the amazement of your bandmates. Theory Lessons 22 interactive lessons with smart visualizations explain intervals, chord construction, voicings, slash chords, diatonic harmony and all major chord types – from first explorations on the fretboard, through major, minor and dominant 7th to altered, sus, add, 6th and diminished chords. Quizzes Use the quizzes to test and internalize your knowledge through play. The quiz tasks cover many topics: chord construction, intervals, harmonic context, chord types, voicings, tensions and much more.

FretBuzz is an application for learning jazz guitar chords and their inversions. It covers: - Triads - Diatonic Triads - Spread Triads - Quartals: Three note chords by fourths, p4 p4, p4 #4, #4 p4. - Four Note Diatonic Quartals - Shells (Freddie Green Chords) - Drop 2 Chords - Diatonic Drop 2 Chords - Drop 3 Chords - Diatonic Drop 3 Chords - Drop 2 & 4 Chords - Rootless Voicings (Bill Evan's A and B Form piano voicings adapted for guitar.) All possible inversions of a chord is covered. Triads have three inversions, seventh chords have four inversions, etc. All possible string combinations of a chord is covered. Triads can be played on string sets 6-5-4, 5-4-3, 4-3-2 and 3-2-1. Drop 3 chords can be played on string sets 6-4-3-2 and 5-3-2-1, etc. This is not a "One Million Three Hundred And Sixty Six Chords For Guitar" application. And also this application does not have any open string chords. Rather this application covers the basic building blocks of jazz guitar chord vocabulary. Two chord diagrams are shown for each chord. The above chord diagram shows the chord notes while the below diagram shows the degrees within the chord. This way you can form an understanding of the structure of each chord you practice and you can use this understanding to create other chords. The play button plays the inversions in succession - in a loop with a metronome beat - and switches the tabs/inversions accordingly so that you can practice along the app. In this mode you do not have to change the tabs/inversions manually. You can also set the tempo of the play along. The tempo can be adjusted as low as 40 bpm, especially useful when learning new chords/shapes. Tapping on a chord diagram plays the entire chord. Tapping on a degree/chord note plays the individual degree/note. I made this so that I can practice when I am away from my guitar, and also for making sure I am not playing wrong notes when practicing. There is also a mini tutorial on how to create altered chords from basic chord shapes. You can resize the chord diagrams for your device. There is also a left handed option in the settings.
