TylerE, please forgive my ignorance: in which kinds of ensembles do you find pairs of horns with different transpositions that are nonetheless numbered as a single group? This isn’t a practice I’m familiar with, but of course I’m not familiar with the conventions of every possible ensemble in every historical period.
I’m not the OP, but Dvorak Symphony Number Eight for one. Two horns in F and two in D, numbered 1,2,3,4. I’d like to be able to easily do what the OP wants as well. (Also, the D horns in this case are D basso, written in Bass Clef BELOW sounding pitch. It would be great if Dorico provided for that possibility, which is common in music of that era.)
While we’re on the subject of Horns, I’ve always been taught (and felt) that they are really a group of their own, about halfway between woodwinds and brass. That kind of bracketing and grouping are very easy now but it would be cool if Dorico officially had an option to treat them that way by default, if wished. Then it would be easy to show tempo making, metronome, etc., at the top of Horns and also at the top of Brass, both, without disrupting anything else.
Well, one score I looked at was the Strauss Alpine symphony. Horns 1/2 are in F, 3/4 in Bb (basso). Also the Wagner tubas (2 Tenor, 2 Bass) are numbered 1-4.
Actually, looking around at scores on IMSLP I’m having a hard time finding scores where this isn’t the case.
Brahms 1: Hn 1/2 in C, 3/4 in Eb
Brahms 2: 1/2 in D, 3/4 in E
Brahms 3: 1/2 in C, 3/4 in F
Brahms 4: 1/2 in E, 3/4 in C
Balaikarev 1: Clarinet 1/2 in A, 3 in Bb
Berlioz Harold in Italy: Horn 1/2 in G, 3/4 in D
Dvorak 7: Hn 1/2 in F, 3/4 in D
Mahler 1: Trp. 1/2 in F, 3 in Bb
Saint-Saens 3: Horn 1/2 in C, 3/4 in F, Trp. 1/2 in F, 3 in C
Wagner Walkure: Horn 1/2 in F, 3/4 in D
Hardly an exhaustive list but that’s what I found paging through a good chunk of the scores I’ve downloaded from IMSLP.
In fact, I didn’t find a single score out of the ones I looked through that had separate numberings. A few were “2 Horns in E / 2 Horns in C” or just “Horns in E/Horns in C”. But those that actually numbered the players ALWAYS grouped by the coarser instrument type.
It’s certainly possible that modern practice has changed but I generally don’t have easy access to modern copyright-era scores.
Basstrombones normally don’t switch between different trombones (except for the contrabasstrombone for some orchestral pieces), but (professional) trumpet players have got a big case with lot’s of trumpets (and mutes) and they can play different instruments and so the indication for trumpet player 1 in this case is, that he has to take (one of) his piccolo trumpet(s). Makes sense to me …
