Musical lyres (a lyre is a harp-like stringed instrument with a hollow body; some say however that this refers to an instrument that included bellows, akin to that of a bag-pipe)

are tamei (as the musicians would keep coins earned while playing in them)

and the lyres of the Levites (who did not put coins in their instruments)

are tahor.

All liquids (this is actually limited to water, wine, oil, honey, milk, blood and dew)

are tamei (that is they can make produce susceptible to tumah and are themselves susceptible to tumah),

and the liquids of the slaughterhouse (of the Temple, where blood and water used to rinse carcasses would run off)

are tahor.

All scrolls (that have any of Tanach written in them)

impart tumah to the hands (this was a rabbinical decree made to prevent them from being stored with terumah, as that would bring mice that would eat the scrolls),

except for the scroll of the Temple courtyard (as food would not be stored with that, nor would it be handled with bare hands).

The prop horse (this was a wooden horse used by performers; others say this refers to a musical instrument made of wood)

is tahor (as it has not receptacle and is not sat upon).

The batnon (this was a large musical instrument held or strapped to the front of the musicians body; it had a hollow area in which coins were placed)

and the niktamon (a musical instrument resembling a prosthetic leg; it also had a hollow area in which coins were placed)

and the eiros (a small percussive instrument which consisted of a hide stretched over a body shaped like a sifter),

these are tamei.

Rabbi Yehuda says

the eiros is [susceptible to the] tumah of a seat

as the wailer (a woman hired to wail at a funeral) sat on it.

A weasel trap

is [rabbinically] tamei, (as it was said to have the form of a utensil)

and [a trap] for mice (which did not have the form of a utensil)

is tahor.

פרק טז משנה א

All wooden utensils

that broke into two

are tahor

except for a folding table (this refers to a removable tabletop that was comprised of two hinged pieces, each of which on its own could function as a smaller tabletop),

and the multi-sectioned plate  (each section of which was serviceable on its own),

and the sectioned bench (like the above folding table, this had a segmented top, and the segments could each be used on their own)

of a householder;

Rabbi Yehuda says

also the mageis

and the Babylonian kod (these two last items are particular types of segmented dishes)

are the same as them.

Wooden utensils,

from when are they susceptible to tumah?

The bed and the cradle,

when one smooths them with a fish skin.

If one opted not to smooth

they are tamei.

Rabbi Meir says

the bed, from when one weaves in it

three boxes (a bed would be made with a rectangular wooden frame, inside of which a network of ropes would be woven to form the beds surface; according to some once three boxes inside that weave were formed it was susceptible to tumah, others interpret this as meaning that three rows of the weave were completed).
