 However, the use of adult male falsettos in polyphony, commonly in the soprano range, was known in European all-male sacred choirs for some decades previous, as early as the mid-16th century.Modern-day ensembles such as the Tallis Scholars and the Sixteen have countertenors on alto parts in works of this period.There is no evidence that falsetto singing was known in Britain before the early 17th century, when it was occasionally heard on soprano parts.
