The low brass is like the wheel of the band. Without a trombone, baritone and tuba a band is like a car without a wheel or a person with no heart. Which means you can't drive or live. That's pretty serious. Baritone is like another wheel. Both Baritone and Tuba are low foundation instruments of the band.
The baritone/euphonium is comprised of two main parts: mouthpiece and body. When assembling, always tip in the mouthpiece to avoid damaging the rim of instrument & mouthpiece.
To start, place lips in an "em" position, then buzz making a "fly" sound. If your lips are looser it is how most make a "raspberry" or a "horse" sound. Make sure your mouth is solid, but not tight against the mouthpiece. Breathe in deep from the diaphragm to support the note you play.
Make sure you are sitting up on the edge of the chair, feet flat on the floor, head in a normal resting position, and bring the instrument to you. Buzz your lips before bringing the mouthpiece to you. Keep the corners of your mouth pulled back. Elbows should be relaxed and slightly away from your body.
Valve oil, Mouthpiece
Empty condensation EVERY time you use your tuba or baritone/euphonium. Press down the valve while taking out the matching tube to empty the condensation. Put a brush through the mouthpiece regularly. Wipe down the instrument with a microfiber cloth and be aware of dents and how they may be caused.
