On saxophone, you don’t have the luxury of playing chords all at once- they can only be arpeggiated.  But that doesn’t mean you should slack off and not understand the chords as well as a guitar or piano player!

A triad has three notes the root, third, and fifth.

The seventh chord adds the seventh on top.

These chords can all be inverted to change it up.  (first inversion, second inversion, etc.

The root defines the name of the chord, but it’s generally played by the bass if you’re in a group.

The fifth is the same note whether it’s a minor chord or a major chord, so it doesn’t really define the character of the sound.

The third and seventh are the active ingredients.  They make the sound of the chord.

Having a minor third makes a minor chord minor.  You can have a minor or major seventh on top and it will still be a ‘minor’ chord.  You will use a different type of minor scale for it depending on the seventh though.

So keeping that in mind, that the thirds and sevenths are what matter the most, you can emphasize these notes when you take solo to show the changes in the chords.
