Hi. The fifth valve provides a concert F, or in other words all the
partials of an open single F horn. The fourth valve often has two
slides so you can switch to the concert A; very good for playing horn
in E. The other slide is a bit longer to allow correction of about
3/4 of a step to allow correction of stopped horn. I don't know
about five valve single F horns, but there are a number of single Fs
(and double horns) with a stopping valve added into the mix. I use
a Geyer 4-valve single Bb horn and have two interchangeable slide
tubes for the thumb valve. It is very nice for "Auf dem Strom", for
instance.
Another variant of recent vintage is the five valve Bb horn on which
the fifth valve is an ascending switch from Bb to C Alto. Alexander
and Paxman have both produced such models; I've seen them at IHS
workshop exhibits. There may be others. My playing days are
essentially over so I sold my Alex 102, a compensating Cor
Ascendant. (The new owner seems to be well-pleased with his new
acquisition.)
CORdially,
Paul Mansur

An on-line friend (trumpet player) is asking me questions about a
five valve single horn (that plays w/ a beautiful tone). Am I
correct to assume this is a Bb horn? Or have five valve single
horns been made in F, too? I was told the 4th & 5th valves are
operated by the thumb. I know one of the extra valves provides
pitch correction for hand stopping, but what might the other valve
provide?
