I was wonder if I could get any advice from learning
trumpet and still playing the clarinet I've heard that
it could mess up your embouchure? I wanted to know if this
was really true.
thanks guys

I tried the trumpet once, didnt like it and didnt really practise too much, but i;ve never heard anything about it messing up your embrocher, but it could?

if you've been playing for a while and thus your clarinet embochure is relatively well established, as long as you practice both instruments in balanced amounts, you'll most likely be fine. switching back and forth in close succession could be hard, but if you give your lips a chance to cool down after playing one before playing the other it works.
i march mellophone, and recently began playing french horn, and it hasn't had any negative effects on my bass clarinet embochure.
my friend has trouble playing oboe even several hours later on the same day after he plays horn, but we suspect thats the double reed thing.

Most people that I've talk to have said that the embouchure required for playing a brass instrument is so different than one for a woodwind instrument that it wouldn't have any negative effects.

I've been playing clarinet for 5 years now and i just took up trombone.
So far I'm really not having any problems. You should be okay so long as you build up good lip muscles for both instruments.

As long as you don't try to go straight from one to another, and keep practicing both, it shouldn't be a problem. Right now I'm keeping up with Bb and bass clarinets, tenor sax, and flute, while learning trombone, and it isn't a huge issue, just alot of practicing.

well...i have been playing clarinet almost half my life nine years!
and i wanted to play french horn but my teacher said no!> and he was dissapointed i am 2nd chair in our band and he said i cannot because it will mess up my lips since brass instruments dont mix with reed!
at first i thougth it was a bunch of balogna but then i started to notice there is a kid in our class who plays trumpit and just to show off that he can play many instruments *he really cant* he switches every year and he is acctually a saxophonist! *thats his reall instrument that he ever first played for 4 years in a row* he was awesome being 4th chair out of 11 saxes! now he is last b.c he uhmm well suks! he sqweeks a lot so yeah it pretty much does affect your lips! he only played trumpit for marching season! another reason i kow is i experimented myself i took a french horn from our class lol and played it a couple of times for a week and during band class i was having problems fixing my luips for the high register keys!....so yea i no longer play the french horn i want to though!!!

i have a question ...if i want to play flute will it effect my lips?

if your school is one of those that ONLY marches durring marching season, (like, no concert band durring marching season) and that kid just put down sax for a few months and played trumpet, then picked up sax again once marching was over, then yeah. that explains that. you have to practice both in moderation with eachother if you want to play two radically different instruments.

my personal rule (though i occasionally break it): bass clarinet gets the most practice. if i'm going to practice, say, mellophone for half an hour, then i'm going to also try and practice bass clarinet at least that long that day. although i don't apply this rule if i want to practice clarinet, because it's similar enough. so sometimes i just play clarinet instead of bass.

I doubt the sax guy is last chair because he switched, its probably more because he didnt practise
and no flute wont mess it up, I've been playng flute off and on for pretty much as long as the clairnet and its been fine, my music teacher playes both instruments as well so its all good

i have played brass and clarinet i started with brass but when i switched to clarinet i found that it was easy to play and i was good in brass but it doesnt mess up anything
