Is my logic correct? The open horn is Bb. With the 4th valve alone depressed, the horn is in F (down a perfect 4th) With the 5th (D) valve alone depressed, the horn is now in D (down a minor 6th). From Bb: P4 + m6 = m10th or Gb. I wouldn't be surprised to learn that I misunderstood the entire post or (more likely) I bollixed the math or (most likely) both.
