Whether you play guitar, piano, ukulele or charango, this tool allows you to instantly visualize over 10,000 chord diagrams and chord charts with their detailed compositions.
Multi-instrument chord generator
The chord generator supports four instruments: guitar, piano, ukulele and charango. Each instrument has specific diagrams and charts adapted to it, allowing you to learn and practice your favorite chords on the instrument of your choice. Guitar chord diagrams show positions on the fretboard, while piano chord positions and piano chord charts show the keys to play on the keyboard.

Main features
Custom chord selection
Choose the root note (C, D, E, F, G, A, B) and its quality (Major, Minor, Diminished, Augmented, Sus2, Sus4). Then add extensions (7, 9, 11, 13) and alterations to create enriched and complex chords suitable for all musical styles.
Random chord generation for learning and practice
The random generation mode is designed to help you learn chords and practice effectively. Use the random generation button to discover new chords and enrich your musical vocabulary. You can also hide the chord diagrams and charts to practice playing chords from memory, which strengthens your memorization and instrumental practice. This feature is ideal for learning, improvisation, composition or simply to explore new sounds on your instrument.
Composition table and intervals
Each generated chord is accompanied by a detailed table showing its composition in intervals (root, third, fifth, seventh, etc.). This pedagogical tool helps you understand the music theory behind each chord and progress in your learning.
Advanced options
Explore chord inversions to vary your positions, use the alteration switch (♭/♮/♯) to navigate between sharps and flats, and take advantage of the triads mode on guitar to work on your specific positions. All diagrams and charts are available for free and in high quality.
