Today I worked on learning a song by ear, and the rhythm guitar part consists of one chord only. The shorthand would be x x 11 11 11 11, the notes are Db, Gb, Bb and Eb.
I came up with 3 possible names for it, although I’m not sure my guesses are entirely correct. Any help with choosing the best option would be welcome.
Option 1: the functions in the chord (from lowest note to highest) are 1, 4, 6 and 9. It could be called a Db6/9 but there’s no 3rd in it so it may not qualify as such.
Option 2: the functions in the chord (from lowest note to highest) are 5, 1, 3 and 6, i.e. a major triad and a major 6th, so this would be Gb6 second inversion.
Option 3: the functions in the chord (from lowest note to highest) are b7, b3, 5 and 1, i.e. a minor triad and a minor 7th, so this would be Ebm7 third inversion.
Thanks in advance for your help
