THE RECORDER IN BRIEF
A DESCRIPTION OF THE RECORDER
The recorder can be identified by 2 main characteristics found together:
1- a mouthpiece consisting of a windway and a labium
2- an octave hole (thumb hole) behind the instrument
A block or fipple inserted in the top of the mouthpiece forms the "floor" of the windway.
The recorder has 8 holes (including the thumb hole). The bottom two are often double. It is a chromatic instrument. Because there is no key mechanism, nearly all the semitones are played with fork or cross fingerings.
The left hand is normally placed above the right hand on the instrument, but this has not always been the rule..
Most recorders, have a range of two and a half octaves. However renaissance consort recorders usually have a smaller range of less than two octaves.
The most common sizes used today are the soprano (or descant) in c, the alto (or treble) in f, the tenor in c and the bass in f. The alto has become the main solo recorder.
How recorders work
A SHORT HISTORY OF THE RECORDER
The origin of the recorder goes back to the Middle Ages. Few medieval recorders have survived, but one of the oldest known ones was found under the foundations of a house built in the 14th century in Dordrecht, in the Netherlands.
The instrument has continually evolved over the centuries. During the Renaissance it was mainly used for consort music and different sized recorders were made and played together.
From the 17th century onwards the recorder became a solo instrument. The soprano was the dominant recorder in Northern Europe, whereas the g alto continued to be used in Italy.
At the beginning of the Baroque period, the design of the recorder changed considerably, giving it a wider range and more virtuoso possiblities. From then on recorders were made in three pieces to make precise boring of more complex internal profiles easier.
There is an interesting article on the recorder of this time in Diderot & d'Alembert's Encyclopédie
After the middle of the 18th century the instrument was no longer loud and dynamic enough to compete with the flute and fell into oblivion for about 150 years. It therefore escaped the changes brought to wind instruments during the 19th century and was not equipped with a key system.
The recorder was rediscovered in the beginning of the 20th century and came back into fashion around 1960 with the revival of early music .
The design of recorders continues to evolve today.

THE RECORDER TODAY
The recorder is not only a historical instrument. It has also found a place of honour in contemporary music, and many composers of our time have written pieces for it.
School and study recorders are usually produced industrially, in plastic or in wood, whereas more specialised, top quality instruments are handmade in small workshops, using traditional methods.
Woods commonly used for these instruments are boxwood and grenadilla for solo recorders, maple, pear and other fruit woods for consort recorders.
Here are some other names for the recorder:
flûte à bec or flûte douce (in French), Blockflöte (in German), blokfluit (in Dutch), flauto de pico or flauto dulce (in Spanish), flauto dolce (in Italian), and flauta de bisel (in Portuguese).
