I've started playing the oboe this year as long as playing clarinet for the 6th year, Both my teachers (clarinet and oboe) and my conductor told me that i can't play on both, and yet half an year has past and I'm still playing both instrument.
so I'm wondering what are the consequences of playing these two instruments at the same time?

Hi, my name is Josh, and I have also benn playing clarinet and oboe side by side, along with a few other instruments. I don't believe their is any consequences to playing both. The only one I can think of is your embrouchuer, and if you practice enough I don't believe it will get effected.

Hello fellow doubler,

The oboe and the clarinet are only different at the extremes. An altissimo scale on clarinet is almost the same as on oboe, except for the extreme notes. The main difference is the weight of the clarinet, spacing of the keys, and embochure. Just keep playing both and you will do fine.
