Your work on pearl pendulum has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
The rhythm gets faster
the sounds gets further apart and the rhythm gets slower.
I had to tilt the bracket slighty forward @ a 11 oclock position in order for the rhythm to be steady.
when the bracket was parallel with the side of the book ithe sounds got further apart. As i rotated it 45 deg the sounded somewhat the same but it had more hits, when i rotated the bracket perpendicular to the spine of the book speed increased and there was less hits then the position before. My next position seemed to have less hits but at a faster pace. another 45 degree rotation allowed for the most consecutive hits in the shortes amount of time. Another 45 degress had more hit than over a period of time. The final position allowed for the similar amount of hits in a longer time period.
the positon parellal to the spine allowed the most hits in both front and back positions.

the motion of the pendulum is decreased each hit
as the pendulum hits the bracket engery is transfered to the bracket lessing the altitude ot the pendulum.
the first hit is the pendulum at its highest peak and at the second hit it is at a higher peak than the fourth hit.
the second hit is still signicantly higher than the fourth and sixth. by the fourth hit the pendulum has little energy left and the hits from the fourth to the sixth are faster.
the first interval is longer than the subsequent time intervals
to increase because the distance being traveled pendulem is reduced allowing for more hits in less time.
with a longer string the more energy is gathered and results in more hits.
Please let me know if you have any questions related to this experiment.
