Abm7 is another difficult ukulele chord that will take some practice. Start with the index finger on the first fret of the G string. After that the middle finger plays the second fret of the E string and the ring finger plays the second fret of the A string. When we have those fingers in place, we swing the pinky up to the third fret of the C string. You will have to move your middle finger back a little to make room for the others. It is a cramped chord so make sure all the notes are ringing clearly.
