We can play Gb major with a full or partial barre chord, depending on what works best. Start by putting the index finger across the entire fret, with just a little bit hanging over the top. All four strings need to have contact so they will all be pressed down; you may need to make adjustments until the tones are clear. A partial barre can also be done by only covering three strings. After the barre we place the middle finger on the second fret of the E string and the ring finger on the third fret of the G string.
