i just `got` a jazz clarinet from a friend
he knows that i play the clarinet, so he gave it to me
now i see that it doesn`t have the same keys
how do you play this thing?

What do you mean the same keys? how is it different? what is the instrument, specifically?

forgive me for my pour english, maybe i don`t use the right words
i will take a picture and post it
the fingering is different, not as many buttons to push

There isn`t a thing like a "jazz clarinet" all kinds of clarinets are used both for classical and jazz music. Probably you just got one of the clarinets they use down in the southeast europe (can`t remember the name but there is different systems).

there`s:

Boehm system (french):

Jules- there certainly are jazz/klezmer/ethnic style clarinets!

It might be one of those smaller Eb Clarinets,or a different system clarinet that is custom made.

i now have a picture

just found out it is a B flat clarinet
does anyone know how the right notes are on this instrument

Sniper,

This doesn`t look exactly like a German clarinet (actually, not even close). But for the most part, you should be able to use a German fingering chart for it.

Without the extra keywork that a German clarinet normally has, I`m really curious as to how in tune this clarinet is with itself. Let us know!! Good luck.
