C# Minor Sixth chord (C#m6) on the guitar fretboard

The C# Minor Sixth chord (C#m6) is made of C# (the root), E (minor third), G# (perfect fifth) and A# (major sixth). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

The minor sixth adds a major sixth to the minor triad, which keeps the dark third and lifts the top note. Its four notes repeat across the neck and share a shape with the half diminished chord on a different root. It sits next to the minor triad and the minor seventh.
