And if I rest two or three counts and try to play a high B, the horn sounds
the B on the staff instead of high B. I've asked different people, playing
different mouthpieces, to try the horn, and all get the same result. What
could the problem be?

That would be my first port of call - sounds like one or both of the
octave keys pads is stuck. Might be worth giving them a clean with
some lighter fluid.
There are three pads in all, the 'body' key is a dual pad affair.

One other piece of information may help the diagnosis. Of the the notes
controlled by the palm keys, high D will sometimes sound without scaling up
to it. But never high Eb or E.
Stephen: In the review of the YBS 62 on your site, you mention that
"There's a dual octave key system too, or rather the upper octave key vents
at two places. This is presumably to improve tone and tuning of the upper
register. I did have to re-balance this mechanism...." What symtoms were
you addressing?
Thanks to you both for your response and ideas.

There's your problem then.
The twin keys should open from octave middle D to G - from A and above
the other octave key opens ( and the twin keys should close )
Depress the G key and try lifting the twin octave key cups with your
finger. If they lift freely ( i.e, the pads aren't stuck ) then it
appears your octave key mech is out of balance - and I'd advise having
it looked at by a repairer ( it's not the sort of job I'd recommend
for home tweaking )..though see below..
If lifting them appears to solve the problem, use lighter fluid to
clean the pads and all should be well.
As regards the twin key cups, they're balanced to each other by a
small spring and a bit of felt - which is supposed to be a
self-regulating mechanism. It doesn't always work out like that in
practice though, and the mech may need an initial setup.
The symptoms were a loss of clarity and tone between mid D - G.
One problem that this mech suffers from is that underneath the lower (
I think ) of the two key cups there's a flat spring that rests on the
sax body. It can pop out of its little channel on the body..and if
that happens there's no power to open the key cups.
This could well be what's up with your bari ( assuming it's not just
sticking pads ), in which case you need to gently poke the spring back
over into its channel.
At some point it will be worth having your repairer check the
tightness of the spring screw...because if the spring has come out
once, it'll come out again until it's better secured.
It's a design fault - easily rectified with an appropriate tweak...but
nonetheless one that shouldn't be there on a pro-spec horn.
However, the source of the problem is not the register mechanisms. When I
said that "the two octave keys located close to the top of the crook never
opens," I had simply failed to notice that the spring had come out of its
place. Once the spring was re-sprung, the register mechanisms worked
properly.
The original two problems were (1) that when I played staff E followed by B
above the staff, the horn produced staff B rather than upper B, and (2) that
the notes controlled by the palm keys will not sound unless I scale up to
them (actually, they sound, but an octave lower than they should).
The first problem has, for the most part, responded to the repairer's care.
But the second remains unchanged. Could the vent tube be the source of the
problem?

Now that you've established the octave mech works, I would guess that
the next thing to check is that the octave key vents themselves aren't
blocked ( use a pipe cleaner..you should just be able to work it in
the hole without having to remove the keys ).
Check the water key cork too...a slight leak here will cause problems.
Other than that I has to be down to a leak or a mechanical fault
somewhere...and the quickest fix for this is to have it looked at by a
repairer.
There's only one other reason why a YBS62 won't function...

Could be something really silly...like something stuck down the top
bow or the bore. I've been caught out with mouthpiece and end caps
wedged in the bore before now!

Thanks for the compys!
Haven't published outside the site....might be an option when I'm too
knackered to play anymore...or when someone makes me an offer I can't
refuse!
Hope you liked the MP3....happy days!
Cheers,
These are indeed nice pieces. And I like your sound clip.

Cheers!
I'd forgotten just how good the band could sound at times..and how
bad.
On the same tape is a disco version of "Singing in the rain" - and
it's bad...very, very, very bad. Get's a good round of applause
though...perhaps out of relief that it's stopped!
