Canzonas Americanas

Canzonas Americanas

I’m a little behind on this. Canzonas Americanas was released last November, and since then it’s received decent reviews. The Guardian says Alarm Will Sound plays with “panache,and Anne Midgette of the Washington Post placed the album in her best of 2012. (And the consumers on Amazon and iTunes seem to like it as well.)

The recording contains all music of Derek Bermel, including the title work Cazonas Americanas which was written for the LA Phil in 2010, Three Rivers (2001), Continental Divide (1996) and Hot Zone (1995). In addition to AWS, the album features vocal performances by Luciana Souza (Grammy award winner) on Canzonas, Kiera Duffy on At the End of the World (2000) and Timothy Jones on Natural Selection (2000).

I like that the trombone actually gets some work in Derek’s music. In Three Rivers the trombone is part of the funky, lugubrious, dissonant line that occurs throughout the piece.

Three Rivers - Excerpt 1

The part is entirely playable on tenor trombone with the exception of one low B that happens towards the beginning but has a feel that is very well suited to the bass trombone.

The trombone also participates in the smoother, quicker cascading passages (one example is at 1:30, the trombone has a more prominent role in the subsequent entrances) that recur.

Three Rivers - Excerpt 2

There are also good times to be had for the trombone in Canzonas Americanas. Check the first movement for things like this:

Canzonas Americanas - Mvt 1

This passage is part of a pretty densely scored section. I found I had to play fairly loudly to be heard (c. 1:40):

And the third movement has a nice passage where the brass joins the fantastic electric guitar/bass part:

Canazonas Americanas - Mvt 3

The rest of the disc is just as interesting. Natural Selection  is written in a way that makes the ensemble sound bigger than it is. The trombone range is wide: in the third song “Got My Bag of Brown Shoes” it goes down to pedal F and as high as E at the top of the treble clef (with some other “as high as possible” pitches). The first song, “One Fly,” reminded me of the fly episode of Breaking Bad, so I give you the Bermel/Breaking Bad mashup.

Bonus: Derek also arranged some Conlon Nancarrow for Alarm Will Sound that we recorded for our album a/rhythmia. Lots of trombone work to be done in this one too. The opening looks like a no brainer for the bass trombone. The trombone should hocket with the bassoon to form the boogie woogie piano part. If you have short arms like me you can end up doing damage to yourself trying to play all those low C’s on a tenor trombone.

But just a short while later in the transcription the trombone part has a duet with the trumpet that takes it up to E flat at the top of the treble clef, a decidedly un-bass trombone lick.

The challenges make it fun. Do your best to enjoy it if you ever have the chance to work it up.

 

 

Everything You Never Cared To Know About the Trombone Glissando

The single most common “mistake” I see in trombone parts is the unplayable glissando. Perhaps the most famous is from the fourth movement of Bartók’s Concerto for Orchestra:

Excerpt from the third trombone part of the Fourth Movement of Bartók's "Concerto for Orchestra."

Excerpt from the third trombone part of the Fourth Movement of Bartók's "Concerto for Orchestra."

Can’t do it (for reasons I’ll explain in a bit) but ugly little things like this keep turning up in my parts, maybe because one popular orchestration book calls it “perfect.” (Cough, Adler, cough.)

To his credit, Bartók probably knew what he was doing when he mocked Shostakovich. More than likely he was writing for someone playing a bass trombone pitched in F which would make this lick most playable. But 99.9999% of trombones today are pitched in B flat bringing us to the question of “what makes a trombone glissando possible?”

tl;dr: scroll down to the “Exhaustive List” below.

The Harmonic Series (You Should Know This)

To know what gliss a trombone can do you have to first understand the harmonic series, then understand the layout of the trombone.  If you don’t know anything about the harmonic series take a second to digest that info (particularly the section “Frequencies, Wavelengths…”) I’ll wait here.

K, welcome back. Octave, fifth, fourth, major third, minor third, flat minor third, etc. You’re a better person now.

The Trombone (It’s An Extendable Tube)

Now let’s talk trombones. You’ll generally be dealing with one of two types: tenor trombones and bass trombones. There are plenty others: alto trombones, soprano trombones, contrabass trombones, piccolo trombones. They all work in the same basic way. Know what key they are pitched in and you are well on your way to figuring out how they tick.

As I mentioned, the vast majority of tenor and bass trombones are in B flat. This means if you blow through the instrument with the slide all the way in you will get a note from the B flat harmonic series. Most professional tenor trombonists can reliably produce notes from the fundamental (B flat below the bass clef) to the twelfth harmonic (F at the top of the treble clef). Professional bass trombonists should be able to play at least up to the D below that F:

B flat harmonic series (the A flat is unusably flat)

You can extend the slide (longer tube = lower sound) for six half steps giving you each down to the E harmonic series starting on the E two octaves below the bass clef:

E harmonic series

For a bass trombonist the low E should be no problem. Depending on your tenor trombonist, that low E might be doable/might not. For tenors you should be safe down to the A flat:

Lower than that, ask your player. The more astute reader may notice that there are some notes missing, a fat diminished fourth from B natural below the bass clef to the E flat just above it. Trombonists have devised systems for playing these notes that open up opportunities for even more glissandi.

Valve Systems (More Options/More Confusion)

To make the trombone fully chromatic (or close to it) from its lowest to highest register, trombonists usually have a valve and extra tubing on their instrument. When the player presses a trigger and opens the valve the tube lengthens making the pitch lower. Professional tenor trombonists usually have a valve that will lower the pitch of the instrument by a fourth pitching them in F (giving them the F harmonic series when the slide is all the way in):

F harmonic series

F harmonic series

Remember, that low F may not be playable by your tenor trombonist.

Here’s where things can get confusing. As you move the slide out with the valve depressed each subsequent half step is slightly further apart. In the end, the F valve (also called an “attachment”) can only lower you a fourth to the C harmonic series:

C harmonic series

C harmonic series

You guessed it, that lowest C will probably not be playable by your tenor trombonist. Now tenor trombonists are only missing one note: the B below the bass clef. For special occasions they can pull the tuning slide out on the valve section and lower the pitch of the valve to E giving them the E harmonic series down chromatically to the B harmonic series. You need to decide whether your occasion is special enough to ask a trombonist to do this.

Bass trombonists generally have two valves available to them and here’s where things get really wild. There’s no real standard for what keys their valves are pitched in. Generally, they all have an F valve and some other valve that will give them that low B. One common system is one valve in F, the other in D (or the combination of the first and second will give D).

See below for a slide position chart by Dr. Jurgen Faisst that shows approximate positions and harmonics for the B flat trombone, the trombone with the F valve depressed and the trombone with a D valve engaged (notice that with the D valve the trombonist can only get a major third):

Slide Position Chart

Possible Glissandi (The Exhaustive List)

Using the info above we can construct layer upon layer of glissandi.

B flat trombone:

With the open B flat trombone these glisses can be as wide as a tritone. The first conceivable gliss would be from pedal E to pedal B flat but because of its extreme low register it’s not playable by all tenor trombonists:

The remainder of these glisses should be fine:

F valve:

With the F valve depressed you get these glissandi (maximum of a perfect fourth):

Not playable by most tenor trombonists.

The next two glisses overlap with those possible on the open B flat horn. The next unique glissando would be:

Any glissando higher than these can be produced without the F valve.

D valve:

With the D valve engaged you get:

Low even for a bass trombonist (but playable by many).

And…

Any glissando higher than that is playable either with the F attachment or on the open B flat trombone. You can use any of those in full or in part and have a playable glissando on the trombone.

Extending the Glissando

This is why the glissando from the bass trombone part to Bartók’s Concerto for Orchestra is not possible on most modern trombones. (Most, but not all. There are some valve combinations that can handle it.) To get from that B to that F you have to cross between two harmonics. When you cross harmonics you get a “bump,” an audible break in the sound (think switching from normal voice to falsetto). Much like a vocalist can work to minimize the noticeability of his break, a trombonist can do the same. With the ability to hide that change and some quick slide motion larger glissandi can be achieved. Take for instance:

Or, better yet, if you’re working with more than one trombone you can begin another player on the pitch on which the first player ends:

Examples

In use the glissando can sound anywhere along the range of hokey to eerie. The hokiest probably being Lassus Trombone, the bane of every trombonist’s existence:

And the eeriest may be from the last movement of Ligeti’s Chamber Concerto. The trombone rises from the unbearably long oboe tone. (Side note: this movement covers basically the entire range of the trombone from pedal F to F at the top of the treble clef.)

Michael Daugherty uses the trombone glissando beautifully in the last movement of his Motorcity Triptych. First in a bluesy bass trombone solo then in a ethereal plunger mute passage with the trombone section.

Michaela Eremiasova uses the gliss to create an undulating texture and to add tension.

747 by Jim Pugh and David Taylor begins with parallel glissandi between a tenor and bass trombone.

The fourth impromptu from Jan Koetsier’s Five Impromptus (for trombone quartet) contains a glissando passed between the members of the ensemble to create a continuous gliss. (The continuous gliss starts around 0:33.)

Harmonic Glissando

A similar technique is the harmonic glissando.  This is where the player quickly moves through the harmonic series.  I’ll cover this in a future post.

Ask A Trombonist

Finally, when you’re done writing your part send it to a trombonist and have them check it out. They should be able to tell you relatively quickly if what you’ve done works. Look, here’s the email address of a trombonist right here: michaelclayville (at) gmail (dot) com.
