A German manufactured soprano recorder for school use: "OEBRA Shulflöte".
It naturally uses the German fingering system. Made of sycamore, moutpiece dark coloured.
How it works:
The airflow is set in vibrations by a sharp edge. The tone is determined by the length of the tube. Opening a fingerhole makes the tube apperar shorter; the tone gets higher. Some tones require opening of more fingerholes, in order to prevent the air in the remaining tube to start svinging, thus making the tone false. The rest of the tube (marked with green wave) tries to take influence, and the tone that becomes a result is a compromise between the open fingerhole and the whole tube. Therefore the diameter of the fingerhole also has influence on the obtained tone. Instruments with "German" fingering system are identifyed by a smaller 5th fingerhole, on baroque fingered instruments the 5th fingerhole is larger than the other fingerholes. These Instruments are fingered different, even if the distance between the fingerholes are almost the same. Thus the fingerhole diameter can be used to obtain a comfortable fingering.
