Sharp 5 or flat 13? Sharp 9 or flat 10?
Let's say I'm in C major. I have a dominant altered chord built on G. This very popular voicing has the following tones (I'm including both enharmonic spellings for the accidentals): G B (D# or Eb) F (A# or Bb) I'd call it a G7#5#9. A saxophonist I know called it G7#9b13. So I'm curious about two things: 1. Who's "right" and why? 2. Do the two spellings imply different scales? Which ones? Thanks for any help.
