It's shame there are only 3 of these in the world; such a beautiful instrument. Having a complete saxophone family keyed in C and F in compliment with Bb and Eb would be amazing
@@paulcohen2556 I bet! They truly are a wonderful set of horns; I wonder when the F baritone/sopranino will finally enter the fray into the world of modern saxophones.
Didn't Adolphe Sax originally intend for another set of saxophones in C and F? These were meant for orchestral use and probably had smaller bores; the familiar Bb and Eb models were wider and would be used in bands. This particular instrument, the Khylbass, sounds like Sax's original vision for the bass saxophone - an addition to the orchestral winds as a specialized bass instrument, richer, stronger, and more tractable than the bottom end of the bassoon.
Yes, Adolphe sax did plan and made saxes in C and F as well as Eb and Bb. The first saxophone he made was a bass in C. The bore of the C and F models were proportionate to the Eb and Bb; they were made to look and sound like Eb and Bb, but just in another key (and the resultant change in a smaller size - not bore- instrument). The Khylbass is in no way like Sax's original bass saxophone, either in bore, range or mouthpiece design. It's many 21st century distinct features are unique to Eppelsheim's vision and design.
The bore of the instrument is much smaller than that of a conventional bass saxophone. Eppelsheim designed the instrument to accommodate an alto mouthpiece, and even provided one with the purchase. (Caravan large chamber)
It's become a fan favorite! And it is relatively light, and so compact that it is easily transportable. And designed to be played on an alto mouthpiece.
