Small-Interval Multiphonics

On the occasion of the publication of my article on Kazuo Fukushima's Shun-San in Flute Talk May/June 2010 and Robert Dick's upcoming masterclass in Bremen (July 6, 2010), I'd like to elucidate some ideas about multiphonics.

Working on Shun-San got me thinking about small-interval multiphonics (those with an interval of an augmented second or less). The first line of advice on how to produce these comes from Robert himself, and can be viewed here. His advice is fantastic, spot-on and humorful, I recommend viewing it.*
*Although I don't agree with what Robert says in regard to offset G flutes or doing sit-ups, but that's another story.

In my Flute Talk article, I touch on the subject of small-interval multiphonics. This passage has elicited some raised eyebrows and questions. To begin, I'll site the passage:

Flutists often encounter difficulty with small-interval multiphonics because they are hung up on trying to produce a focus immediately. That is difficult to do when you are blowing in two directions at once. The irony of these small-interval multiphonics is, at first, you have to unfocus to get the sense of focus. Open up the embouchure hole and let both notes in. Initially there will be a lot of air, but with practice you can refine them. They will sound focused and rich because of the very low difference tone caused by a close interval. When you get the hang of playing these small intervals, it may help to focus on producing this difference tone rather than the individual notes themselves. That may seem strange but sometimes it works.

The first point of confusion may arise in that I assume the reader is already familiar with Robert Dick's advice: get to know the dynamic range of each note first. Then, keeping a constant airspeed, use the angle of the air to find both notes. If you don't research the gamut of air speed for each note, you'll never find the small range of speed that overlaps and works for both.

This is what I meant by having to unfocus to get the sense of focus. You need a constant airspeed and a wide angle at first that will let both notes in. Please forgive my artistic crudeness, but here hopefully you can see where the angles overlap. If your focus is too narrow at first, you may miss the range where the angles overlap.

Now, to explain that bit about the low difference tone. An explanation of difference tones can be found in Wiki. Often is is not an actual, distinct tone that I hear. Rather, it is just a low sort of humming sound, or it's as if something opens acoustically at the bottom - a feeling rather than a sound.

I hope this has been of help. Some of those multiphonics in Shun-San are hair-raising! Even someone like me who has been familiar with them for years needs to put in serious practice time on them. It is a good refresher!

Paradies Remembered

It's been over a month since the marathon premiere of Karlheinz Stockhausen's Klang cycle. I have been wanting to share the experience here, but I survived the project with too many mixed feelings. However if I don't get it out, my blogging energy may get permanently clogged. Also, Robert Bigio, the editor of Flute (the journal of the British Flute Society) has entrusted me with another project: a feature on Kathinka Pasveer. So it's time to get my thoughts in order.

Paradies is an 18-minute work for solo flute with electronics (8-channel tape). It must be played eyes closed, from memory, while wearing a specific shade of pink (HKS31, it's called in the German textile industry). A shirt in this color, worn with white pants and shoes, is also acceptable. The piece does not require movement on stage or any sort of choreography.

I have performed this piece 12 times between April 24 and May 29, 2010, and will perform it again in November in England.

Most of the questions that come my way have to do with how I managed to memorize the work. It is nowhere near as daunting as one might think because:
1) The piece uses the same series of 24 pitches over and over, mostly in sequence and only occasionally in easily recognizable variations. Analysis of this work is a no-brainer.
2) The player is involved in the compositional process.

To begin, I must explain that the work has 24 strophes. Each of these strophes has two parts:
1) a ritornello in which a melody is given but the dynamics, speed and articulation are decided by the player (this is the "involved in the compositional process" part)
2) a composed insert. The composed parts are called inserts because they may be inserted at any point during the ritornello. (Theoretically. This piece is fraught with unwritten rules, and the insertion of the composed insert must follow certain guidelines not given in the score.)

I began work on the piece after New Year's 2010, so had just over 4 months preparation time. There was no way for me to memorize the piece from the outset, since the ritornelli needed to be worked out and played for Kathinka. I didn't want to write anything onto hard disk only to have to erase it later. What I did memorize from the beginning was the structure of the piece. That in retrospect was a good idea. By the way, the ritornelli's dynamics, speed and articulation should be worked out rather than improvized. Whether you write them out or not is up to you. If your memory is at all visual or photographic, as mine partially is, I recommend writing.

I also realized the sooner I had a good version of the ritornelli, the sooner I could begin memorizing them. So my first order of business was writing the ritornelli. During the first rehearsal with Kathinka (January 25th), I ended up having to erase about two-thirds of what I had written, having trespassed many of the unwritten rules. By the time of the next rehearsal with Kathinka, on April 1st, we had a version that we could both be happy with and I could start the memory work in ernest. At that point it was not difficult. The ritornelli had been worked on for so long that memorizing them came easily, and the structure and the composed inserts had already been memorized.

I hope readers were not expecting a full discorse on how one memorizes music. For most of us it is an individual combination of visual, analytical and kinesthetic elements. For me, it is perhaps
Visual = 10%
Analytical = 10%
Kinesthetic (muscle memory)= 80%

Some of my tricks included
1) Setting a time schedule by working backwards from the date of the performance. Divide and conquer. Don't try to memorize all at once but set a certain amount for a certain time period.
2) Going through the piece without the flute in hand or the music in front of me. This I often did in the dark before going to sleep.
3) Procrastinating as much as legally possible in order to have the peace of mind required for clear intellectual work. This means taxes didn't get filed, Spring cleaning waited until Summer. Sort of the buy now, pay later strategy. If you can afford it, it does work.
