About the Compensating
System
The pitch of long tubular instruments such
as the euphonium becomes slightly higher
than the true pitch when multiple valves
(the 4th valve in combination with the 1st-
3rd valves, etc.) are depressed at the same
time. The compensating system provides
pitch correction in such cases. It also allows
the playing of fast passages in the low range
without having to change fingerings for the
1st through 3rd valves when the 4th valve
is depressed.
The YEP-642/YEP-842/YBB-632/YEB-
632 are equipped with a compensating
system.
The compensating system on the YBH-831
corrects the pitch when the third valve is
used in combination with the first and/or
second valves.
Before You Play
Always store the instrument in its case
when taking a break, during transport, and
after playing.
Always remove and disassemble the lead-
pipe assembly before placing the sousa-
phone or marching tuba series instruments
in their case.
About the mouthpiece
The mouthpiece that is supplied with
your instrument is a standard mouthpiece.
The mouthpiece is designed to fit into the
mouthpiece receiver without being loose.
Do not treat the mouthpiece roughly, drop,
or damage the mouthpiece, etc.
* The bell on the euphonium or tuba may be
positioned opposite of that shown in the above
illustration depending upon valve position and
case design.
