i often see people writing clarion registers etc.
i have no idea what they mean (well actually a bit but...) and i want to know what range of the Bb clarinet is what register etc.
Thanks for all the help!

Chalumeau; Bottom E to throat B flat (E3-B flat4)
Clarion; All fingers B to high C (B4-C6)
Top/Altissimo High C# to top C (C#6-C7)
Extreme Alt. Anything you can get above that.
Sometimes the area between thumb F and the B flat above is referred to as the 'throat' register

The standard instructional materials/tutorials like Klose, Rubank, etc. divide the clarinet into three registers. They are as follows.
Chalumeau - the lowest register - normally from the lowest note to Bb that is played thumb and register key. Mathematically, these notes are the fundamental (also called 1st harmonic) that can be played with the clarinet at the given length set by the highest open hole.
Clarion - the middle register - normally from the B natural in the middle of the treble clef to the C two ledger lines above the treble clef. Mathematically, these notes are the 3rd harmonic of the chalumeau note.
Altissimo - the high register - normally starting at the C# two ledger lines above the staff and including all of the notes above it. Mathematically they are the 5th and higher harmonics of the chalumeau note.
Some notes can be played in different registers. For example, when trilling from Bb (thumb + register) to the C in the middle of the staff by using the side trill keys, the C is then a chalumeau note (i.e. first harmonic) even though it is normally played as a clarion note (i.e. third harmonic) using all seven fingers, thumb and register key. C# above the staff can be played as either a clarion note (3rd harmonic) or altissimo note (5th harmonic) depending on the fingering choice.
The term throat register is often used but it isn't really a register. Not all references use it but it is a convenient short hand way of refering to the notes from open G to throat Bb. It would really be more correct to refer to the throat tones rather register as they are all first harmonics and thus a subset of the chalumeau.
The term extreme altissimo is not universally used either and definitions vary from source to source.
Another term sometimes used is "high" register applied to the lower portion of the normal altissimo range. Again the definition varies from source to source and is not universally accepted.
