Gynaecology is the medical practice dealing with the health of the female reproductive system (uterus, vagina, and ovaries). Literally, outside medicine, it means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system.
Mari Kimura (木村 まり Kimura Mari) is a Japanese violinist and composer best known for her use of subharmonics, which, achieved through special bowing techniques, allow pitches below the instrument's normal range. She is credited with "introducing" the use of violin subharmonics, which allow a violinist to play a full octave below the low G on the violin without adjusting the tuning of the instrument. Polytopia is her first CD for the Bridge label, and her first created without collaborators.
