New-designed and intuitive chord charts for accordion

This website offers a series of new-designed chord charts that can help you learn the most commonly used chords in many different genres. These charts are designed to be clear and intuitive, making it easy for both your left and right hands to find the right positions and combinations. All chord charts are specifically designed for Stradella bass system and piano accordions, and are suitable for players of all levels.

If you’re a beginner or an experienced player, can help you improve your accordion playing.

Accordion chord chart example: the bass charts are in “mirror view” and keyboard charts are in a vertical perspective to mimic the accordionist point of view.


Why bass charts are in mirror view and the importance of touch for accordionists

As an accordion teacher, I always emphasize the importance of using touch to navigate the bass position on the accordion. Sight is not a viable option when playing the accordion, and relying on mirrors or attempting to look at the bass buttons can actually hinder progress and reduce confidence.

The marks on the C and other buttons are meant to be felt by the fingers, not seen by the eyes. It’s important to rely on our sense of touch to orient ourselves on the button board, as it’s the only sense available to us while playing.

This is why the bass charts on are presented in “mirror view,” which reflects the way the left hand “sees” the bass button board. Over time, this perspective will also become the way you visualize the standard bass layout in your mind.

If you struggle to use these charts, try consulting them while holding the accordion. Having your left hand on the button board should make it easier to understand the mirror view.


The versatility of Stradella bass system accordions: from traditional to modern music

A Stradella bass accordion, depending on its size and number of buttons, has one or two columns of single notes (bass and counter-bass) and up to 4 columns of chords (major, minor, dominant 7th and diminished 7th) but it can play many more types of chords in all keys.

Contrary to popular belief, the accordion is not limited to traditional or classical music. The left-hand technique for playing the accordion has evolved, allowing musicians to fully tap into the potential of this instrument.
