To get the high G on the recorder we will only use our left hand, although it is a high note is not difficult to get.
Our left hand will cover the first three orifices, the one, two and three and we will also cover the back orifice but only a little, approximately half.
Notice the flute drawing of how to write the high G for recorder on stave:
This note is perfect for practicing in combination with the lower G on recorder because the only thing we have to modify is the half opening in the back hole.
Now we are going to practice with some flute exercises with the sharp sun, as always we will gently release the air from our lungs, come and practice !
