Traditional alphorns are made in two long, curved, trough-like halves, carved by hand and then joined. I took an easier route and constructed this long, straight horn from four boards. The bore shape being square in cross section has less effect on the resulting sound than you might expect. The important thing is that it expands over its length, allowing it to function as a conical tube. Since this instrument has no valves or side holes, getting different notes is a matter of finding the harmonic resonances of the tube through embouchure control. I’m not a horn player myself, and hearing what skilled brass players can do with this thing has been a thrill for me.
Sorry, no audio clip is available for this one.
