About this app

Chord Analyzer is an interactive, reverse chord finder.

If you don't know a chord on a score, if you're looking for the best notation for a composition, or if you're looking for an original position for a chord on the guitar (or on another stringed instrument), then Chord Analyzer is for you.

Chord Analyzer provides a bridge between stringed instruments (guitar, banjo, mandolin, ukulele, etc.), the piano and American chord notation.

Press the keys on the piano or the frets on the guitar, and the application will recognize the chord and indicate its most appropriate notation. Also choose a chord from the dictionary to see all the positions that can be played on the guitar or banjo.

Thanks to a powerful algorithm, the application is not limited to known positions and offers many more suggestions than the classic chord dictionaries. Listen to them, play them, modify them directly on the application and make the best choice for your compositions or interpretations!

In the full version, the application proposes to extend this intelligent and interactive chord dictionary system to more exotic instruments (7-string guitar, Ukulele, mandolin, banjo, violin...), offers to bookmarks your favorite chords in order to work them later and above all... works with open tunings! Don't be afraid to retune your instruments because you won't be able to find the positions of all your chords quickly.

Also enjoy a piano-guitar interface to efficiently exchange between guitarists and pianists on original or complex chords.

Features:

- Easy to use application.
- Over 3,500 chords recognized, from the simplest to the most complex
- Chord detection for Piano, Guitar and Banjo in all positions and inversions.
- Complete dictionary for Piano, Guitar & Banjo
- Algorithmically calculated chord positions for guitar and banjo.
- Transcription of scores and intervals
- Smart" detection of the most appropriate chord notation
- Real-time audio transcription of chords
- Encrypted bass management
- Slash bass management
- No advertising

Available in full version:

- Piano-guitar interface
- Bookmarks
- Left-handed neck
- More instruments: 7-string guitar, Ukulele, 5-string Banjo, Violin, Mandolin, etc.
- Open tuning

Whether you are a beginner or a professional, Chord analyser] will allow you to better understand the American chord notation and to enrich your playing.

This is a great app in all respects and upgraded to the paid version. But I did hit a problem, which I think is a bug! When using the Ukelele I started saving chords to Favourites so I could make a song sheet. This worked fine except when I entered any chords that where barring across all four strings. For instance I wanted the chord for all strings barred behind the 2nd fret. It correctly identified this as Bm7. But the Favourites key was greyed out so I couldn't save!

A good app, and I’ve enjoyed playing around with it, but I’d like to be able to change the guitar tuning from Standard to Open D (DADF#AD) tuning and there seems no way of doing this. As a result, the app is of no use to me. UPDATED: realised the Pro version allows for Open tuning. I’ve upgraded and am very pleased with the purchase. I’ve also upgraded my star rating to 5 stars.

Really useful tool for learning and visualising the guitar both on the free and premium verisons. While initially, i thought this would be like any other app and a subscription based model, i was pleasantly surprised with the app being a one-time payment. I appreciate the sentiment and chose to purchase it. The premium version is a great tool for learning and versatile across different instruments, I would highly recommend it to any musician

Thank you so much for that feedback. Yes my goal was to provide a tool for musicians, without ads or hidden costs, and with a free version really complete. It's really good to see people that appreciate this.
