Cockhestra

The art of creating an orchestral ballad with a timbre of male sex organs, slapping against their owners pelvic/stomach regions until said symphony is achieved. Bass notes created with fully erect penises whilst treble is created with flaccid ones (semis can be used at conductors leisure). Ornaments such as acciacaturas are performed with scrotum. If attempted please be wary of sexual arousal resulting in changes of penis rigidness thus changing the required pitch.
