The descant recorder , also named soprano recorder, is the most common size played. It is a relatively easy instrument to produce a sound.
The lowest note is C which sounds one octave higher than middle C. Music is written one octave lower than the sound produced. The range of notes played spans just over two octaves.
Many people learn the descant recorder for a year or two and then move on to another instrument such as the flute, clarinet, oboe or even the violin. Playing the recorder first makes learning a second instrument much easier as you have learnt the basics such as note names, note lengths and reading the notes.
