Rhythm Bead Necklaces are  jewelry for your horse.
otherwise known as "Speed Beads." by  barrel racing and
other speed events) Rhythm beads are great for , trail riding, training ,pleasure riding and desensitizing young horses,
and as part of your parade oufit .

On the trails, the bells help warn wild animals that
you're coming through, so that they leave your path
sooner and don't spook your horse by fleeing
when you're almost on top of them. Some horses are actually soothed by the music of the bells, and are less likely to
spook at unexpected noises/sights.
Also, the soft jingle of the bells
accentuates the rhythm of horses' gaits, which is useful for adjusting the tempo/rhythm of a horse's movement, and for helping the rider to move in rhythm with the horse.
