C minor Accordion Chord Chart
Minor chords are built by taking the root, the 3rd, and the 5th notes of the major scale and then lowering the 3rd by one half-step (a semitone). The formula for a minor chord is R, m3°, 5°. They can also be built by combining a minor 3rd interval with a major 3rd interval.
For example, let’s take the first three notes of the C major scale: C, E, G (root, 3rd, 5th), now subtract a half-step from the 3rd and you get a C minor (C, Eb, G). If we analyze the intervals of this trichord (aka “triad”) we find that between C and Eb there’s a minor 3rd and between Eb and G there’s a major 3rd.
One of the defining characteristics of a minor chord is its minor 3rd interval, which gives the chord its distinctive sound. Compared to a major chord, which has a happy and bright sound, a minor chord sounds sad and serious. This contrast between major and minor chords is an important aspect of music theory and is used by musicians to create a wide range of emotions and moods in their compositions.

Minor Chords on Accordion
The Stradella bass system allows you to play a minor chord by pushing just one button. On a standard bass accordion with at least *24 bass buttons, minor chords are between major and dominant 7th chords, on the 4th column (or on the 3rd column if your accordion doesn’t have the counter-bass column).
