Hi,
I'm not exactly a
young
composer, but I do own and play a heckelphone (among other things). Even though there are approximately 100 heckelphones in use around the world, new works are still being written for the instrument (see, for example, the new contrabassoon concerto by Aho). I've played a number of orchestral works by Adam Gilberti (now at UCLA) that call for heckelphone, sarrusophone, tubax, contrabass flute, , contrabass saxophone, serpent, glass harmonica, and other similarly rare horns. I know these works have been performed at least twice, with all the rare horns included. Logistically it is not easy, but it is possible. ;)
How about a
contrabass saxophone quartet
? (The musicians in this video are, from left to right: Adam Gilberti, the composer, on Eb tubax; me, on Bb tubax; Jay Easton, on contrabass sax; and Blaise Garza on contrabass sax.)
Sure, if you don't know musicians who play the horns you want to write for, you may have difficulty scheduling a performance. You can't just release your work to the wind and expect orchestras to pick it up and play it. Of course, this applies to
every
new work, whether it includes rare horns or not. On the other hand, if you are adding to the repertoire of an unusual instrument, it will be of immediate interest to the players of those instruments.
Getting back to the heckelphone, the expense is mainly a result of the complicated keywork, and the fact that any professional instrument must be carefully and well made. Heckel
does
still make new heckelphones, perhaps 1 or 2 per year, and the price is comparable to a Heckel bassoon (not cheap, but not unreasonable). One can also now substitute the
lupophone
, made by Guntram Wolf in Germany. This instrument has a bore and timbre very similar to the hecklephone, with a range extended down to low F (there are a few Strauss works in which the heckelphone part descends that low, despite the fact that all heckelphones only reach A or Bb). Other substitutes for the heckelphone are the bass oboe (which has a similar timbre, but not as robust) and the tenor saxophone.
Feel free to ask me about instrument ranges, fingering, and orchestration :)
