8. The right tools for the job

Although it isnt unusual to find players disregarding a composers instructions about what instrument to use—frequently the specified instrument simply is not available—it is profoundly irritating to find editions that beat the player to it.  An example of this is the supposedly scholarly edition of Bizets Carmen edited by Fritz Oeser (Alkor [Bärenreiter], 1964), where the parts Bizet wrote for cornets-à-pistons are labelled trumpet instead:

I say supposedly scholarly:  the use of trumpets is the least of this editions faultsand some of these will certainly feature in future posts.  In any case,  Winton Dean beat me to it fifty years ago, demonstrating that the Oeser edition goes disastrously off the rails from sound editorial practice (p. 284).  Dean also remarks on the trumpet/cornet issue, pointing out that this mis-allocation had already happened in the Peters edition edited by Kurt Soldan (on the IMSLP here) although at least Soldan had the courtesy to add Pistons parenthentically underneath.

The instruments are regarded as interchangeable, probably because the cornet  (properly with accent on the first syllable, which makes it easily distinguished from the cornett) is virtually an endangered species, particularly in the USA.  A hundred years ago it was the other way around, and the trumpet seems to have taken over in the 1920s (with perhaps the coup de grâce being Louis Armstrongs conversion to trumpet).  Thus we find Cecil Forsyth, writing in his Orchestration (1914/rev. 1935):
We must not forget that the contempt which is usually bestowed on the Cornet by those who have never heard it properly played is mainly a contempt because it cannot equal or beat the Trumpet in Trumpet passages.  These simple and straightforward phrases were always consciously designed by the old masters to produce their somewhat oppressive effect by the mere weight of the instruments tone.  In course of time we have come to associate that type of tone with that type of passage. (p. 107)
Erring on the side of oversimplification, the conical cornet is a melody instrument; the cylindrical trumpet is a rhythmic instrument, with a tone better able to cut through an ensemble.  To best illustrate the timbral difference between conical and cylindrical brass I suggest this performance of the piece we usually call Jesu, Joy of Man's Desiring (from BWV 147) by the German Brass.  The arranger has cleverly divided the ensemble into a two distinct consorts.  For most of this arrangement, the 4-part chorale is played by cylindrical instruments (one trumpet and three trombones), while the rest is played by conical instruments (two flugelhorns, two horns, tubaalthough at a two points a piccolo trumpet joins in, and in the final measures everyone is playing together).

Here is a handy diagram, from Anthony Bainess Oxford Companion to Musical Instruments (1992), which compares the profile of several brass instruments, although it warrants a few comments below.
SOURCE:  detail of scan of Baines, p. 43 (entry:  Brass instruments). 
Baines does not clarify this, but this diagram must assume that no valves are depressed, nor is the trombone slide extended; 
V then would indicate the passage through the valve section of the instrument, but not diverted through the crooks the valves would engage.  
Otherwise the proportions don't make sense, as (for example) nos. 4 and 5 at their full length would be much closer to #1.
A mountain out of a molehill?  Profiles 4 and 5 do not appear vastly different from each other.  Indeed, but the modern B-flat trumpet is significantly shorterand thus proportionally more conicalthan its predecessors in the Renaissance and Baroque, and indeed even down to the early twentieth century.  The old valved F trumpet of the late Romantic orchestra (an instrument which will figure in a later post) really would sound noticeably different from todays ubiquitous B-flat, as the F trumpet has a narrower bore and is about half-again as long.  (Its profile would most resemble #1 in Bainess diagram, although a little shorter.  I dont think Ive ever heard one live, although it can be heard on some of the recordings of the (new) New Queens Hall Orchestra; otherwise it is essentially extinct.)  If Bizet had been asking for trumpets in Carmen, he would have been expecting something of that sort—not the instrument we see and hear today.

Note that profile 6 above is only the shorter portion of the standard double horn today (F/B-flat); the F side would extend off well to the right, and would thus be proportionally more cylindrical.  For orchestral horns, the principle that the longer the instrument is the more cylindrical its profile has always been true:  even before valves, with the crooks players would use to change the key of the instrument, the low crooks produce a very different sound from the high crooks.  Listen, for example, to these recordings of the opening chorus of Bach's cantata Sie werden aus Saba alle kommen (BWV 65) with either C alto or C basso horns:

It isnt just the pitch, but the whole timbre of the instrument that is changed.  At the extreme:  the shortest horns of which I am aware are the E-flat alto horns in Mozarts K. 132 (the higher pair of two pairs of horns), which make a very round, bugle-ish sound.

In the ensembles that put pairs of cornets and trumpets togetheras so often in French nineteenth-century literature, or in military band musicone may frequently find composers observing a distinction between the writing appropriate for one or the other.  Thus in his wind band piece Sea Songs, Ralph Vaughan Williams neatly distinguishes between cornet solos and trumpet solos, and (as below) demonstrates how to keep trumpet punctuation from overwhelming cornet lyricism, while still sometime needing either instrument to function as the other:

Likewise, Emamanuel Chabrier knew when to let the trumpets do the heavy lifting in a thick texture, relegating the horns and cornets to filling in the harmonies:

Working on this post got me wondering of any instances where a composer calls for a player to switch between the two instruments.  It seems like an obvious expedient, but it is curiously rare.  The published full score of Bernstein’s Candide reveals that for the Parisian waltz the first trumpet player takes up the cornet (an allusion, perhaps, to the showy cornet part that Berlioz added to the Valse of his Symphonie Fantastique?)  In the last movement (Marcia funebre) of Bartók’s Four Orchestral Pieces, op. 12, the four trumpet players switch back and forth between trumpets and cornets, although it would be hard to demonstrate that he is absolutely consistent with the sort of idiom he gives to one or the other instrument.  

But in other instances where one might expect such a practice, it just doesnt happen.  In Gilbert & Sullivans Iolanthe, for example, the fanfares which begin the chorus Loudly let the trumpet bray are played by cornets, Sullivans default in the Savoy Theatre orchestra.  (Like Bizets Opéra Comique, this may have been a balance issue more than anything else; when Sullivan wrote his grand opera Ivanhoe, he called for trumpets—and even a Wagnerian bass trumpet.)  Seldom do I hear cornets in performances of the Savoy operas.  The rare cornet solo does strike my ear as odd on the trumpet, though.  Compare the solo in the overture of The Pirates of Penzance (by Sullivan's assistant, Alfred Cellier) in these two performances, one with trumpet (at least to my ear, although the player is trying to compensate with a fair bit of vibrato) and the other with cornet.  I note that the Kalmus score (apparently scored from parts) gives no indications that the cornet was what Sullivan had in his ensemble:

I started this post remarking on performers disregarding the instructions of a composer, and have given a few examples of editors doing it.  I have been wondering if we could imagine an editor imposing cornet where a composer wrote trumpet?  Has this ever been doneoutside of brass band transcriptions?  I can think of a place where Id like to do it:  the Tango-Pasodoblé” movement of Waltons Façade.
SOURCE:  scan of William Walton Edition vol. 7, Façade Entertainments, p. 42 (detail)
This seems to my ear to be begging for a cornet (with its quotation of I do like to be beside the seaside), but Waltons tiny ensemble calls for trumpet.  Changing that is the sort of liberty a conductor is free to do, but not an editor.
