Gb Major 6, written Gb6, is built from Gb, Bb, Db and Eb: the root, major 3rd, 5th and 6th.
Its 3rd and 6th, Bb and Eb, are its guide tones: they say what kind of chord it is, so voicings are built around them and the root is often left to the bass.
In the progressions here, Gb6 is the I6 of the Rhythm Changes in Gb.
