Using a rootless version of C13 in the piano left hand makes Lilypond call it an E variant. I can't figure out how to override chord names so I'm using markup, like this. What am I doing wrong?
leftHand = \relative c, { \clef bass \key c \major \time 4/4 <e' a bes d>4^\markup { C13 } <e a bes d>4 <ees g a d>^\markup { F13 } <ees g a d> } << \new Staff = "lower" \leftHand >> } Thanks!
