Helmut Finke applied for a patent on July 3, 1975 for the basic idea with two separate lead pipes for each side of the horn. It was first implemented on a Bb / high F treble double horn, then transferred to the triple horn and now used in this new design. The advantage is an independently tunable high F section and a long leadpipe on the B side that is not interrupted. This system has significantly reduced the tonal difference between the two sides of the horn.

In the concertos written between 1740 and 1800, the baroque horn is mainly played in its highest register, because here the naturals are close together. After the horn had been increasingly scaled in the course of the Classical and Romantic periods and the "clarino" position was no longer playable, the horn concertos by Leopold Mozart, Fiala, Neruda, Josef Reicha, Sperger and others had to be adapted for trumpet. The Bb/High F treble double horn, however, allows the above mentioned works or other late baroque or early classical works to be performed again for horn. At the same time it serves as a full Bb horn. The illustration shows the Bb/High F treble double horn with A stop valve.
