I haven't played that long, and I don't know very much about this, but when I try to play my clarinet together with a piano, it sounds like it (the clarinet) is a bit out of tune. Is it some kind of technique I don't know about?

The clarinet is usually tuned in 442 Hz and the piano in 440 hz. There for you have to push the barrel out a bit. Maybe you even have to buy a new and longer barrel 66/67 mm to sound great with the piano.

It could be simpler than that even! If you have not been playing for very long, it is probably just that your embouchure - the muscles round your lip have not yet formed into a totally suitable position. If you are a beginner I doubt you would would notice the difference betweem 440 and 442.

Don't worry about it, its probably just about time. Why not ask your teacher?

I know, barrel, you can put in or out, which changes the sound. Also, for fun one time i tried to play sharp and it worked. I forgot exactly how, but if you push more air it might work.

No offense, but if you haven't been playing that long maybe you could have forgotten that your clarinet is in Bb and the piano is in C?? This is just my opinion, because if you played the same note on the piano and on the clarinet, you will definately be out of tune because they are a semitone apart!!

I could be wrong...this is just my opinion :D

i think peder would know... i cant really tell if im in or out... but i can surely tell if im playing a different note.

Try getting a chromatic tuner. It actually tells you whether or not you're sharp or flat. If you're sharp, push in the barrel, flat pull out.

ok so if your tuning it doesn't matter what your tuning to really well it does but u know say if your tuning with some1 and u can here a woble with the sound then one of u two is out of tune..but if you are sharp pull your barrel out a bit i think it's out anyways and it will go abit flatter but if flat make sure all your peices are lined up correctly and that it's pushed in all the way. i think

if your piano isn't perfectly in tune, a chromatic tuner won't do you much good. listen and play with it, and guess if you're flatter or sharper than the piano. Change your barrel or joints accordingly. play again, and if it got better, you were right, but if it got worse, you need to change the other way!
to quote my band director- "when you're tuning, do something. if it works, great, if it doesnt, try again." and to quote my director quoting some random person- "what do you do about pitch? anything."

i know you weren't trying to be patronisng music-ace44 but I thought you were slightly so if you're going to be, then get it right, the clarinet is indeed tuned in Bb and the piano in concert pitch, but that makes them a whole tone apart not a semitone.

Anyway tuning becomes an issue for two main reasons I find, if the clarinet is cold it will be flat (or warm will be sharp) the other problem could be your embouchure. Temperature conditions can be sorted out by blowing air into the instrument and pushing the barrel in as far as possible when the instrument is flat (I often have to this before a concert to be in tune with the rest of our orchestra) or pull out the barrel if you're sharp. If your embouchure is the problem then the only thing that will sort that out is practising loads, especially long notes. Hope I've been of some help. Shelly Belly x
