The main members of the woodwind family are flute, oboe, clarinet, bassoon - and saxophone!
'But saxophones are made of brass', - a reasonable objection.
The saxophone is the newcomer; only 180 years old and like three of the woodwind instruments, it is a reed instgrument, i.e. the sound comes from the vibrations of reeds.
By then, 1840, many metals could be forged or worked into lots of different shapes; brass, in particular, being used for many purposes previously the domain of wood..
The saxophone is single-reed instrument: this means that it is played with one reed attached to a mouthpiece.
The FLUTE has the logest pedigree of all wind instrument, the first, hollow bones with holes bored into them for different notes..
For the next 3000 possibly longer, years the material was wood, and now metal. although wood flutes are still played,
More recently, cheaper and more robust plastic models are becoming popular as a learner's first flute. http://www.nuvoinstrumental.com/products/flute/
The sound of an OBOE, rather like the violin, can be excruciating in the early stages, yet an oboe can produce the sweetest and most most emotional music in the hands of an expert player.. The oboe is a double-reed instrument. Two curved reeds are bound together to form an oval passage for the air to pass through. Composers give the melody to the oboe (or solo violin) when they want to tear at your heart strings.. https://www.youtube.com/watch?v=2WJhax7Jmxs
