The flute is a musical instrument of the woodwind family. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones.
A musician who plays the flute can be referred to as a flute player, a flautist, a flutist, or, less commonly, a fluter. The term flutenist, found in English up to the 18th century, is no longer used.
Aside from the voice, flutes are the earliest known musical instruments. A number of flutes dating to about 43,000 to 35,000 years ago have been found in the Swabian Alb region of Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.
In Hinduism, sādhu (skt साधु sādhu, "good; good man, holy man") denotes an ascetic, wandering monk. Although the vast majority of sādhus are yogīs, not all yogīs are sādhus. The sādhu is solely dedicated to achieving mokṣa (liberation), the fourth and final aśrama (stage of life), through meditation and contemplation of brahman. Sādhus often wear saffron-colored clothing, symbolizing their sanyāsa (renunciation).
This way of life is open to women; the female form of the word is sādhvī साध्वी.
