the word flute, calling the recorder variously the "common flute", "common English-flute", or simply "English flute" while the transverse instrument was distinguished as the "German flute" or simply "flute". Until at least 1765, some writers still used flute to mean recorder. Other languages Until the mid-eighteenth century, musical scores written in Italian refer to the instrument as , whereas the transverse instrument was called . This distinction, like the English switch from recorder to flute, has caused confusion among modern editors, writers and performers. Indeed, in most European languages, the first term for the recorder was the word for flute alone. In the present day, cognates of the word flute, when used without qualifiers, remain ambiguous and may refer to either the recorder, the modern concert flute, or other non-western flutes. Starting in the 1530s, these languages began to add qualifiers to specify this particular flute. Nomenclature Since the fifteenth century, a variety of sizes of recorder have been documented, but a consistent terminology and notation for the different sizes was not formulated until the twentieth century. Modern recorders Today, recorder sizes are named after the different vocal ranges. This is not, however, a reflection of sounding pitch, and serves primarily to denote the pitch relationships between the different instruments. Groups of recorders played together are referred to as "consorts". Recorders are also often referred to by their lowest sounding note: "recorder in F" refers to a recorder with lowest note F, in any octave. The table in this section shows the standard names of modern recorders in F and C and their respective ranges. Music composed after the modern revival of the recorder most frequently uses soprano, alto, tenor, and bass recorders, although sopranino and great bass are also fairly common. Consorts of recorders are often referred to using the terminology of organ registers: 8′ (8 foot) pitch referring to a consort sounding as written, 4′ pitch a consort sounding an octave above written, and 16′ a consort sounding an octave below written. The combination of these consorts is also possible. As a rule of thumb, the tessitura of a baroque recorder lies approximately one octave above the tessitura of the human voice type after which it is named. For example, the tessitura of a soprano voice is roughly C4–C6, while the tessitura of a soprano recorder is C5–C7. Modern variations include standard British terminology, due to Arnold Dolmetsch,
