 Putting the instrument in the

case

Always store the instrument in its case when tak-

ing a break, during transport, and after playing.

Always remove and disassemble the leadpipe as-

sembly before placing the sousaphone or marching

tuba series instruments in their case.

* Th e bell on the euphonium or tuba may be posi-

tioned opposite of that shown in the above illustra-

tion depending upon valve position and case design.

 About the mouthpiece

Th e mouthpiece that is supplied with your instru-

ment is a standard mouthpiece. Th e mouthpiece

is designed to fit into the mouthpiece receiver

without being loose. Do not treat the mouthpiece

roughly, drop, or damage the mouthpiece, etc.

 About the Compensating System

Th e pitch of long tubular instruments such as the

euphonium becomes slightly higher than the true

pitch when multiple valves (the 4th valve in com-

bination with the 1st-3rd valves, etc.) are depressed

at the same time. Th e compensating system pro-

vides pitch correction in such cases. It also allows

the playing of fast passages in the low range with-

out having to change fi ngerings 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 cor-

rects the pitch when the third valve is used in com-

bination with the fi rst and/or second valves.

 About the small hole on the side

of the piston

 Piston for the YCB-623/YBB-623

Th ere is one small hole on the side of each piston

to evacuate air in the valve case. After operating

a valve slide without pressing a piston, and then

when subsequently pressing a piston, a pop noise is

generated caused by internal pressure change. Th is

small hole can help prevent generating pop noises.

 Piston for the baritone YBH-831

Th ere is one small hole on the side of each piston

to maintain the rotation angle of each piston. Th is

hole is neither a vent hole nor a lubrication hole.
