Communicative movement in contemporary chamber music

An article I wrote, “Communicative movement in contemporary chamber music: hand werk in the rehearsal of pieces by Thierry Tidrow and Georgia Koumará” has been published by Divergence Press. You can read it here
Looking forward to feedback and discussion on this!

multiphonic monday – pitch bending multiphonics (Bb clarinet)

First, a couple of general rules for pitch bending on multiphonics:

* The highest audible pitch is the one being bent, and the pitch is always bend downwards, never up.
* Bending a multiphonic often has an effect on its fragility, surprisingly this means increasing its stability in some cases.
* They don’t always work the first time, so clarinetists should try to practise them a little.
* Bending multiphonics sometimes creates different beating patterns which can be controlled (with practice).
* Not every multiphonic can be bent, some are completely destabilised by bending and break (meaning only one pitch will be heard). I’m only including some examples here. Ask the clarinetist you’re working with to help you come up with others if you are using different pitch material. (If this post ends up being popular then I’ll add some more examples down the line!)

As usual these days, fingering diagrams from Bret Pimintel‘s awesome site, and pitch diagrams handdrawn by the lovely Elena Rykova. The following are meant to serve examples, I’ve included audio of the multiphonic alone and with pitch bending, plus some information about each example.

Let’s start with one of the most stable examples. Here is a multiphonic in which the upper note can be lowered without any sacrificing of stability. The quality of sound also remains fairly consistent. I’ve made two takes, first at the easiest dynamic level (mf – f) and then a second at what was for me, the softest possible dynamic.

This multiphonic starts with an extremely high rate of vibrations. As I lower the higher pitch, the rate of vibrating stays relatively stable, only slowing slightly, so that an effect of continuous buzzing continues. In a second take, I bend too far, breaking the multiphonic, and only the fundamental remains. And in the third take, I demonstrate what happens when playing this multiphonic at an unstable dynamic range, namely, a quiet one. The effect is still present, but extremely fragile.

Here is a classic example of a multiphonic that begins in a relatively stable state of purity, and as I bend downwards, the vibrations increase, eventually creating a buzzing effect. I’ve made two takes at different speeds of bending. (Perhaps you can hear this, but it seems to me that it’s more difficult to bend back upwards without things becoming a bit destabilised.)

Pitches (pre-bend) Fingering Audio (without bend) Audio (bend)
 90  90    
 190 190    

These multiphonics begin at a lower dynamic level, very wide intervals and as such, quite fragile. In the first take, I lower the pitch, introducing the vibrating effect until it becomes quite a stable buzzing. In the second, I’ve attempted to do this faster.

This multiphonic produces a very unusual effect when bent at a mf dynamic. It is not the most stable multiphonic to begin with, but when bent downwards, this instability is accentuated. It was impossible for me to maintain a consistent tone, so this ‘skipping’ effect is produced.

 174 174     

Much like the previous example, the fragility of this multiphonic is highlighted through the bending of the upper note. This time, however, the multiphonic tends to buzz as it reaches the bottom of its bend. Another unique effect.

197 197  

It’s quite rare that a multiphonic with a close interval (within an octave and tagged as ‘dyads’ in the app) can be bent in this way. I argue that this is due to the fact that in order to produce these effects, the throat position is already quite open, not dissimilar to the way it is when pitch bending. Still, occasionally this remains a possibility, though the effect is fragile and the bend is rather small.

Reed tapping articulation

A quick one for you today…

Went and saw John Butcher play last night, and he was using this technique, which involves flicking or tapping the reed with the right hand while holding down different keys with the left hand, producing short articulated pizz-style sounds. The bigger the instrument (well, the bigger the reed) the louder this is, he used to great effect in the very resonant space he was playing in.

I can use this technique on any fingerings from middle C (written) to the Bb above on any clarinet, and the resultant pitches are a major second below.

I’ve used a plastic reed on both clarinets while playing around with this, and I can’t imagine any clarinetist will appreciate you asking for such a direct attack on a cane reed: so do ask your player whether they already have some plastic ready for use.

And for further explanation and a demonstration, here’s a short video I posted to my Instagram account. I’ve started adding different videos explaining techniques or how I’m practising things I’m learning, so if you’re on Instagram, give me a follow!

underblown bass clarinet multiphonics

Today’s topic is one of the most beautiful bass clarinet multiphonic effects: the underblown multiphonic. Basically, to create the effect, we use altissimo fingerings, allowing the lower undertones to sneak back in. This is really a follow up post to one I did some time ago on creative ways to make use of the register key. I’d advise having a read/listen through that material before moving on to this post if you want to have a really clear sense of how this technique works.

This post also in a lot of ways follows up on the posts I made about spectral multiphonics (and contra) two weeks ago, and posts on dyad multiphonics (and for bass) from earlier this year. I love categorising multiphonics like this, and I’m hoping that talking about them in different ways helps to give you a greater understanding and the ability to use them more creatively. There is also now a twin post to this one for Eb clarinet underblown multiphonics.

Once again, Elena Rykova has beautifully notated the multiphonics, and I’ve used Bret Pimintel’s site to create the fingering diagrams for the first time. They look great I think and are very clear!

These are all best performed at quiet dynamic levels. Too loud and one risks breaking the multiphonic, with only the top note sounding.

I’ve divided these multiphonics into three categories: one that uses the first register key (and crucially, the venting hole uncovered by the index finger of the left hand), one that uses the second register key (that post on register key usage will be helpful here for clarification) and one that makes use of the throat keys. There are audio examples of each set played in order, followed by a database of the individual multiphonics.

The following example demonstrates the basic series. 

While I’ve left space between each multiphonic here, it would be perfectly possible to play these legato:

 107  107
 108  108
 109  109
 110 110
 111 111
 112  112  
 113  113  
 114  114  

The second series employs the right hand index key, otherwise known as the second register key on the bass clarinet, in order to produce this beautiful set of multiphonics. Here are these 10 multiphonics in order:

And played legato:

 115  115
 117  117  
 119 119  
 121  121
 123 123  
124  124
 127 127  
 129  129
 131  131  
 133  133

The final series in our post today employs only ‘throat’ keys: the register key, A, G# and the top two trill keys. Here are these four multiphonics in order:

 137  137

spectral multiphonics for the contrabass clarinet

Last week I wrote about spectral multiphonics for Bb and bass clarinets and I promised that I’d supply a chart for the contra as well, so here it is.

While I’m talking about the contra, I thought I’d just bring to your attention the two other posts I’ve made about this instrument: there’s a selection of various contra multiphonics  as well as a post about using low register colour fingerings.

You’re hopefully pretty familiar with spectral multiphonics after seeing last week’s post, and not a lot changes when adapting them to the contra in terms of different ways to manipulate the effect, but all the same here are a few examples:

Glissandi work really well and can be very dramatic (here on a low C fundamental):

And I also really love quiet whispery harmonics:

And now the chart. Once again, beautifully notated by Elena Rykova.
