Does anyone here double on trumpet? I got a yamaha trumpet and been playing around with it but I would like to know if it it will hurt my flute chops.

You can do it, it takes awhile to get used to.
For Flute players the trumpet is okay, trombone is probably easier. French horn embouschre is a little different from the other brass.

But when you double you are compromising. Which is not necessarily a bad thing. But as mentioned earlier if you want to be a serious classical flute player it could be detrimental.

I play just for fun. The best I can hope for as far as flute ability is to be able to keep up with the other flutes in the community band I play in. I'm definately not ever going to play professional.

Probably the most critical issue is that you continue to play flute when learning trumpet. Otherwise as your lip muscles develop for trumpet, the flute playing will suffer.

You probably find that you can switch from trumpet to flute without a break but after playing flute your lips will take a few minutes to relax enough to play trumpet.

I wish I could play many winds, all of them if I could. Not being possible, I stick to the flute, it's more than enough for my present capabilities.

But if you feel like doubling I think it is worth the risk, as most probably, in case there was any bad impact on your embouchure, it will be reversible, without any permanent harm. And you will notice any degrading, no doubt, and can stop and go back.

Not to discard that you might find the trumpet more interesting or suited for you than the flute (why not, after all?)

Just tell us what happened, in case you decide to go ahead.

There is not too much wrong with James Galway's flute playing. Written by Galway October 24, 2002:

I play the French horn and saxophone (real bad on both) and it has not affected my embouchure at all. In fact, playing the French horn actually improved it. I became more aware of the changes which are necessary on the flute.
My brother plays the flute, Clarinet and Sax and I think he is great on the flute.

Hey that's interesting and no it has definately not hurt his flute embouchure. Thanks for posting that.
