Pupils either choose for oboe willingly, because they are fascinated by the instrument or by coincidence. Quite often they start at the age of seven, playing parts after one year already. The condition is however they exercise 20 to 30 minutes daily. In doing so they learn the correct blowing technique and develop the mouth muscles.
Oboe is rarely chosen as an instrument though because it is unknown. Astria Oboe Trio have wanted to do something about this from the outset, amongst other with arrangements.
