Mine is probably C sharp ): On the Bb clarinet

On my eb-clarinet it's the high B (on top of the first line above the staff). For some weird reason it comes out WAY to sharp.

I guess the high G on my Bb-clarinet is the "hardest" for me to play but not really an unfavorite

B flat clarinet high G, like high high G the one above the staff with the leger lines, that is with the chromatic fingering being all sharp, flat and unstable, and the alternate fingering for it is in tune for me but it drives my hand crazy, I need to practise running up and down to it

Concert b flat mid range for bass clarinet. oh my god! everyone here knows what i'm talking about.

On my Bb clarinet-High E (on the staff). I recently played a trio with my friends and had high e's all over the place, and I couldn't stop squeaking when I played them. I'm pretty sure it's my clarinet though. It's kind of old. It needs a new mouthpiece. And there is a pad that kept falling out.
On my Bass clarinet-High G and up. They are just mean.

Throat Bb. That is the most horrible sounding note to me. BTW...which alternate fingering are you using on High G? is it TR|1x3|1x3|Eb by chance? I LOVE that fingering for G. But if you over blow a B (one line one space above the staff) you get a G also . I use that fingering quite frequently in Poulenc's Sonata for Clarinet. Most notably in Mvt. 3, Rehearsal Number 3, Measure 4. I use it because it is SOOO easy to use that fingering and go to E right after it quickly.

Mine's probably third octave A and super C.........they sound really bad, they always squeak....then they just stop......

I agree with Dennis. All the neck notes on my yamaha sound dodgy and you really have to pinch the embouchure to get them out.

Its the highest for me, which is about B6, cause its hard, but Bb 4 and C4 are pretty annoying cause i just cant get them to come clear

I really hate playing c sharp too! At the beginning of this year it would come out really squeaky. But now it isn't so hard anymore. (occassional squeaks every now and then)

I ate any not above F.(so above the staff.) I only play Bb clarinet.

I hate that high C sharp/ D flat! It has got to be the ugliest note in the world! Ewww!

I hate my middle B flat... I can't get the same colour in this tone like the others. makes me crazy

Throat tones. they suck.

Middle G#, A, and Bb all suck! You just cant get the same tone with those notes.
