To play Am6 we place our index finger across the entire second fret, leaving just a little of the top to hang over. When we press down, we want all four strings to play with no dead sound. After you have that put your middle finger on the third fret of the A string and the ring finger on the fourth fret of the C string. Make sure the last two fingers stay straight up to avoid touching other strings. For a barre chord it isn’t that difficult to play!
