Hi Lisa,
I play the bones too. First of all I want to warn you for 'over-practising', so watch specially the elbow!
I learned it 55 years ago (9 years old), and picked it up again recently... You know what? It isn't gone. Just like skating, your body will not forget. In my home town playing the clappers was a normal children's street activity, promoted by the town council due to a royal celebration: every child between 10 and 12 became a pair clappers (I was too young to get them, but my father was a schoolteacher) to preform on the queens birthday.
I make a study about the clapper/bones and created a nice collection, which I play if possible (can't manage the Indian karthal).
The matter is rather complex. Because the clapper (idiophone) is so easy to construct and very inexpensive it is used in many a social activity, like dancing, replacement for the church bell during lent term, warning signal for people having a contaminate illness, etc. The English and Dutch navy used the clapper on board the ships to accompany dancing the hornpipe keeping the sailors and marines in shape.
To the dulcimer music I find the rhythm bones a strange combination: to my ears they don't fit...
Much of my bones are bought from Scott Miller, who produces nice sets of ox bones. Adam Klein, the opera singer, makes nice ones too, with a very light sound. Ox bones have a marble like sound, much more tone, but they hard to get. Sanding ox bones is very dangerous to ones health.
What I find the most interresting is the individual aspect of playing the bones. Because I have probably larger hands than you, your bones will sound different when I play them.
I know most American players place the bones one between index-middle and the other one between middle-ring finger. Sometimes the hand is almost stretched out completely. In Europe and special The Netherlands the clappers are set between the thumb-index and index-middle finger. The fingers are held in an open fist to create a resonator body. When the second clapper is placed between the middle-ring, the sound is much lower, which is nice using both hands. Also changing the length of the 'bell-clapper' (hitting the 'bell') by changing the grip result in a different sound.
To me the most troublesome is the repertoir: which songs work and which don't? Of course all sailor songs can have rhythm bones in the arrangement.
Playing spoons? Castagnettes? Maybe a special group about bones?
