 fingering scheme full Boehm variants?
Author: RoBass

Hi Folks,
regarding the discussion about advantages and disadvantages of full Boehm clarinets I rememebered a question from my beginning years.
I found fingering schemes only for standard 17/6-clarinets but not for the full variants.-/

Is there any website or book outside where this tables are published? I'm searching for 18/6, 19/7 and 20/7.

kindly
Roman

The only main differences are with clarinets with the forked Eb/Bb mechanism where xox|ooo gives Eb/Bb - so any 17/7 (with only the forked Eb/Bb mech.), 18/7 (either LH Ab/Eb or artic. C#/G#), 19/7 (forked Eb/Bb, artic. C#/G# and LH Ab/Eb) and 20/7 (+ low Eb) will have the forked Eb mechanism.

With articulated C#/G# you can play B-C#/G-Ab trills by holding the C#/G# key down all the time and trill with RH2.

The extra touchpiece ('sliver' key) for RH2 duplicates the C#/G# key and is used for C-Db, G-Ab and high E-F trills.

LH Ab/Eb lever (which is now the only additional key to most clarinets making them 18/6) duplicates the RH Ab/Eb key so sliding can be avoided. On full Boehm Bbs it makes slurs from low Eb to Ab (or Ab to low Eb) easy, so playing off an A clarinet part with a written low E-A (or A-E) slur is possible.

On clarinets with forked Eb/Bb and articulated C#/G#, passages in flat/sharp keys are made much easier - eg. upper register Gb-Ab-Bb-C (or F#-G#-A#-B#) is fingered as:

F#/Gb - xxxC#/G#|oxo (or following on from an E#/F - xxxC#/G#|xo,o)
G#/Ab - xxxC#/G#|ooo
A#/Bb - xox|ooo
B#/C - ooo|ooo
(and resolve it with a C#/Db fingering of your choice)

Yes, I know this ;-) But where is it shown in scheme? That's the question ;-)

It isn't - it's only ever mentioned in passing.

For the notes Chris P mentioned, I would use the regular fingering vs. the fork Bb. Sometimes it is not an advantage since for some people raising the last two fingers, even if also pressing a finger with the right hand at the same time, is easiler and more natural than lifting pinky and middle fingers only.

You can keep the C#/G# held down for the forked Bb if it's a fast passage.

The Ab/Bb trill with the forked Bb, as mentioned by Chris P is VERY useful, and after years away from my FB, I still try to use it

TR|X0X G# | OOO to TR|XXX G# |OOO

I also frequently, in slow passages reach for the right hand C#/G# sliver key.

I have noted that the LH Eb key's presence on the horn does not guarantee that you'll include it in a "pinkie-tangler" passage. You still have to "groove it in" to your brain, much as you have to plan ahead and pick the "best" pinkie swap or slide to work around its absence. Both implementations take practice, but the LH Eb should be standard so that pre-planning and swap/slide is not required. These are modern times, after all; and few of us actually reach around the bottom of the horn with our right thumbs to fiddle with the left hand pinkie keys any more.

OH,
and the "long" F altissimo fingering with articulated G# horns is:

TR Ab XXX|XXX or TR A XXX|XXX
while one uses

TR XXX C# | XXX on a 17/6 instrument.

... and altissimo Bb with artic. C#/G# instruments is like upper register C, but with the left thumb off the thumb tube (but still opening the speaker key) - Sp. xxx|xxxF/C

I have tried the above mentioned "long" F fingerings using either the Ab or A keys on several instruments including Leblanc LL, Older R13, B&H 926 and Selmer series 9 but found they just do not work for me. The Ab version is always very flat and the A version although sharper is still too low to be useable.

My experiments with long F indicates that the needed vent hole to get it at correct pitch is the lower side (Bb) trill key.
Problem is to get to it !!!
(rested bell on knee and operated key with RH thumb !)

Still trying to think of a simple additional mechanism to lift this trill key, maybe something like an oboe 3rd octave key?

The conventional long F can be faked by "leaking" a very small aperture on lower edge of LH 3rd finger (about 1/8th holing) but tuning is very critical on size of the "leak".

For altissimo Bb I find the following fingering works very well and in tune

sp Ab xxx F/C | xxx Ab/Eb

and it works equally well on non-articulated instrument too.
