see many threads about shaky eggs
and, oh, the bodhran jokes!

(i play bodhran, but it does not
always fit in.)

i used to have a basket of claves,
spoons, maracas, shaky eggs, (and veggies)
and other rhythm instruments for
folks to join in with on jams.

the problem is that most of the
folks who come to a jam without
their own instrument are often
non-musicians, and do not have
a sense of rhythm.

be alert for clues from the
others in the session as to
whether what you are playing
is enhancing the situation
or not.
