I’m not sure I understand how this kind of horn would work. The link says that the valve “allowed trombone players reading in treble clef to play from concert-C parts without transposing.” So suppose I’m playing a treble clef part with the valve engaged, and there’s a middle ‘c’ on the page. In what position would I play it?
It really relates to players using transposed treble clef fingerings (much more common 100 years ago). If you were playing transposed treble, the notes look like tenor clef (i.e. one ledger line below the staff is Bb in 1st position). In transposed treble this note is C. With the valve switched to the alternate position (bypassing the extra loop) the trombone is now in C. If you were to use the same fingerings as you used for transposed treble you would now not be transposing.
If you think I am speaking fluent Nepali, don't worry. It really doesn't apply to you.
There used to be a number of different "preacher" instruments, including trumpets in C, saxophones in C (called C Melody), Baritone Horns in C (now mostly used in Latin Bands), clarinets in C. Of course flutes and oboes are normally in C and don't transpose.
