E sharp 9/ F 9
3 - Ten other chords, same tone
Tip : your first ninth chord?
Reminder: E sharp and F are on the same fret guitar, it is their respective scales that determine their different names! NB: in any scale you should be able to articulate all the notes C, D, E, F, G, A, B, without repetition, which is why we added sharp or flat to respect differences of tones and semitones (more: see the next chord E sharp sus4 ).
