Tuning the Instrument
Slide the main tuning slide in or out to tune
the instrument. Since temperatures have an ef-
fect on the instrument’s pitch, blow some warm
air through the instrument to warm it up be-
fore tuning.
Adjust the length of the main tuning slide until
you achieve the desired pitch.
