Editing Cello (section)

===Internal features===
Internally, the cello has two important features: a [[bass bar]], which is glued to the underside of the top of the instrument, and a round wooden [[sound post]], a solid wooden cylinder which is wedged between the top and bottom plates. The bass bar, found under the bass foot of the bridge, serves to support the cello's top and distribute the vibrations from the strings to the body of the instrument. The soundpost, found under the treble side of the bridge, connects the back and front of the cello. Like the bridge, the soundpost is not glued but is kept in place by the tensions of the bridge and strings. Together, the bass bar and sound post transfer the strings' vibrations to the top (front) of the instrument (and to a lesser extent the back), acting as a [[diaphragm (acoustics)|diaphragm]] to produce the instrument's sound.
