Whales In Music: An Interview With Alex Shapiro, Composer

So a month or two ago, I went down to Greeley, Colorado to see my good friend Masaki Kleinkopf perfom in the All State Concert Band.  One of the songs that they played there was a piece by composer Alex Shapiro entitled "Immersion."  One of the movements in the piece was entitled "Beneath," and it was particularly interesting!  In it, the band played with one of the most musical animals in the world: the whale!  I was very interested in this piece and the work that went into it, so I contacted the composer and asked her a few questions, and she was kind enough to oblige!  I found her answers very, very interesting, and I hope you guys find them as interesting too!

The Natural World:  What made you decide on including whale song in the piece?

Alex Shapiro:  Interestingly, the choice wasn't pre-meditated; the song found me, and I welcomed it in unexpectedly. To back-track for a moment, BENEATH-- for symphonic wind band and prerecorded electronics-- was originally a far more intimate piece for contrabass flute and that very same prerecorded electronic track, titled BELOW. Anyone curious can hear excerpts from both versions of the music: the original solo piece for contrabass flute and prerecorded electronics, BELOW:

And the version I later created, using the exact same track, for symphonic wind band, titled BENEATH:

Around the same time that I was beginning to think about a commission from the wonderful flutist Peter Sheridan for what ended up becoming BELOW, I happened to be poking around on the NOAA Vents Program website (http://www.pmel.noaa.gov/vents/index.html), fascinated by the sounds from our oceans. If I weren't a musician, I might have become a marine biologist, and I also have a fascination with the geology of the ocean floor. I found-- and ended up using to open and close the piece-- a recording of a volcanic eruption from the floor of the Pacific. Perusing the NOAA website, I clicked through to the area with whale songs (http://www.pmel.noaa.gov/vents/acoustics/sounds_whales.html) and from there, I found my way to many other websites with marine mammal audio files. And that's how I discovered the whale who I realized would be a perfect duet partner with Peter. The song was so haunting, I just had to use it as the centerpiece of the music.

TNW:  What specific whale did you choose?

AS:  The recording I use is that of a male Pacific Humpback whale; I'm told that they're the ones who do the best singing. I actually listened to a couple of hundred whale songs from seven or eight different kinds of whales before I came across this heart-wrenchingly beautiful song. I became adept at hearing the differences in the vocalizations of each species, and could identify a Minke from a Blue from a Sperm just from the audio. Orcas-- the most familiar whales where I live on San Juan Island, Washington, are easy to discern because, as members of the dolphin family, they make high-pitched chirps. Like the Orcas, many whales don't have a song that lends itself as well to human composition needs when it comes to melody (I place the blame for this on the limitation of our musical language, not theirs!). Too many short blasts, pulses, and other non-linear sounds (all of which are great for rhythm, though!). But the Humpback really does sound much more like a human voice, and when I found this particular song, I was mesmerized. I went over to my piano and began improvising with it. Amazingly, the whale was perfectly pitched with my well-tempered instrument, and I immediately found harmonies that worked beautifully (thus making it a whale-tempered piece!). The only audio editing I needed to do was to use filters and equalization to "clean up" the sound of the audio file, so that the blanket of low-humming water noises picked up by the hydrophones that recorded the animal, didn't overpower the higher pitch of the song itself.

TNW:  Are you planning on incorporating nature motifs into any later pieces?

AS:  Absolutely! I'm often recording the sounds around me-- from nature, and even from my travels through and across nature, such as last week when I was on the ferry from Friday Harbor to Anacortes, on Fidalgo Island, and used my iPhone to capture a hypnotic rhythmic passage created by the boat engine that I'll use in an upcoming work. And one of my upcoming 2014 symphonic wind band commissions will be centered around recording the sounds of the state of Wyoming, and using them in the digital audio track I create to accompany the band. The possibilities are endless, and inspiring.

TNW: Where did you get the idea to do a piece about Wyoming? Have you already come up with the ideas for the sounds you are going to use?

AS: The piece is an upcoming commission for wind band and prerecorded electronics, commissioned in part by a grant from The Biodiversity Institute, a division of the Haub School of Environment and Natural Resources at the University of Wyoming, to be premiered by conductor Bob Belser and the University of Wyoming Symphonic Band, that will entail me returning to Wyoming to capture the sonic essence of the environment. U of Wyoming gave a beautiful performance of IMMERSION last year (the piece that includes BENEATH, with the whale), and and you can imagine, this new piece is a perfect fit for me!

And again, anyone curious can hear excerpts from both versions of the music: the original solo piece for contrabass flute and prerecorded electronics, BELOW:

And the version I later created, using the exact same track, for symphonic wind band, titled BENEATH:

I would like to take this opportunity to thank Ms. Shapiro for taking the time out of her busy schedule to chat with me!  Hopefully we can ask a few more questions for her once her Wyoming piece is released!  I feel as if I speak for all of us when I say we look forward to hearing more from her in the future, both blog-wise and music-wise!

Bison: Up Close and Personal!

At one point on our Grand Teton/Yellowstone/Sun Valley driving trip in 2006, we went on a ranger-guided nature walk in Yellowstone.  As we were walking along the trail, the ranger told us a lot about the local wildlife, and mentioned at least a few times the dangers of confronting a bison.  The ranger led us into a small clearing surrounded by tree for a short break, when suddenly, a large bull bison wandered by right behind the ranger along the trail.

Everyone froze, staring at the bison as it started blankly right back at us.  Fortunately, it was uninterested in us, and wandered on along the path, without increasing the "Bison Casualty Count" for that year!

Animal Spotlight: Gasparinisaura

Gasparinisaura is just one of those many dinosaurs that are not very famous at all, and not very well known.  In fact, I hadn't even heard of it until this morning, when my episode of Dr. Who made the computer momentarily freeze, so I picked up my Jurassic Park Institue: Dinosaur Field Guide by Dr. Thomas R. Holtz and Dr. Michael Brett-Surman that was sitting next to me on the computer table and turned to page 74.  Learn something new every day!

Gasparinisaura is considered to be a part of the basal, or primitive, ornithopods.  Ornithopods are different from other ornithischian dinosaurs in that they have a premaxilla bone that reaches further than their maxilla bone, and that their jaw joint is further down than in other dinosaurs.  Most of the basal ornithopods were around during the Jurassic Period, such as the Late Jurassic Othnielia rex, who inhabited what would become the rocks of the Morrison Formation of Colorado, Utah, and Wyoming.  Most of the rest of the basal ornithopods didn't survive past the Early Cretaceous Period, but Gasparinisaura has been found in rocks dating from around 80-90 MYA, right smack-dab in the Middle Cretaceous Period of Argentina.  According to the Jurassic Park Institute, "Remains of dinosaurs from this time span are so extremely rare, all the specimens in the world would fit in one small exhibit hall!"

Let's take a brief look at what we know about the evolution and the dispersal of the basal ornithopods, shall we?  According to my massive, 861 page book called The Dinosauria, every member of the clade Ornithopoda (which includes the iguanodonts and the duck-billed hadrosaurs, as well as the basal ornithopods) had a common ancestor that came from Asia.  This is interesting to note, because two other major clades of dinosaurs, the Marginocephalians (which includes the ceratopsians like Triceratops and the Pachycephalosaurs like Pachycephalosaurus and Stygimoloch) and the Thyreophorans (which includes stegosaurs like Stegosaurus and ankylosaurs like Ankylosaurus [yes, I know, that sounded incredibly redundant]) are hypothesized to have originally evolved in Asia, before spreading out to other parts of the world.  Whew, that would have been a mouth-full if I had had to say that out loud.

Anyways, paleontologists believe that this common ancestor would have inhabited Asia during the Early Jurassic Period, or perhaps even before that.  According to the book, prior to the Late Jurassic, a "major dispersal to North America took place."  Following this dispersal to North America, two "subsequent dispersals from North America" followed, one to Europe, and the other to South America.  (Keep in mind that, at this time in Earth's history, the continents were intermittently connected, allowing for the over-land dispersal of animals that would be entirely unable to do the same thing today.)  The European dispersal contained ornithopods of the lineage that would one day lead to the relatively famous dinosaur known as Hypsilophodon.  This dispersal is thought to have occurred before or during the Early Cretaceous.  Meanwhile, the South American dispersal "took place (at the latest) during the early Late Cretaceous," and was composed of members of the lineage that would one day lead to our home-dawg, Gasparinisaura.  Boy, am I the only one who just skimmed those last two paragraphs?

Gasparinisaura, like many of the basal-most members of the ornithopods, was just a little guy, only around two feet long, and probably weighing about as much as a chicken.  Remains of Gasparinisaura are found in the Río Colorado Formation.  With further digging (oh so witty) in The Dinosauria, I have been able to come up with other dinosaurs found in this formation. Here is a list of all of the dinosaurs mentioned in the book. 

Alvarezsaurus, a member of the group of dinosaurs known as the alvarezsaurids, a group of Maniraptoran dinosaurs thought to be fairly closely related to the ornithomimosaurs.  

Patagopteryx, a flightless bird that probably weighed around as much as a turkey.  

Neuquenornis, a small, pigeon-sized bird.  Apparently, paleontologists have not only discovered a partial skeleton of this animal, but also some eggs with embryos!  Pretty neat!  

Velocisaurus, a four or so foot long ceratosaur, not very well known.  A noasaurid, and, as you can see in the pictures below (all four of the pictures are of Velocisaurus), looks a lot like its close relative, Masiakasaurus, whose picture you can see if you click on the word "Masiakasaurus" where it is yellow. 

Aucasaurus, a thirteen or fourteen foot long abelisaur, thought to be a close relative of Carnotaurus.  Known from a skeleton that is quite complete, but not yet fully described.  

Neuquenosaurus and Titanosaurus, a pair of sauropod dinosaurs. 

Antlers Vs. Horns, Part 2: Horns

A horn, unlike an antler, is attached to an animal.  It consists of a bony core, a projection of the bone of an animal, and is covered by a layer of keratin (your fingernails are composed of keratin).  Also unlike an antler, that falls off easily and annually, a horn, if it is broken off, will never grow back the same way.  That is why poachers have to kill rhinos (who have horns) to actually take their horns, as opposed to just letting them fall off.

Many different types of animals have horns.  Let's take a look at a few of these creatures.

The members of the family "Giraffidae," which includes the giraffe and the okapi, both have horn-like things on their heads, called "ossicones."

The members of the family "Rhinocerotidae," or the rhinos, have horns that are composed solely of keratin, and do not have the bone core typical of many horns.  The horns of the rhinos also grow continuously.

Some of the members of the family "Chamaeleonidae," or the chameleons, often have horns projecting out of their skulls, which are covered in a layer of keratin.

And, of course, the members of the family "Ceratopsidae," a group of marginocephalian dinosaurs, have horns projecting out of their skulls. 
Below is a short list of some of the more famous Ceratopsian dinosaurs.

Famous examples of Ceratopsian Dinosaurs (or "Ceratopsians That I Have Heard Of):

1. Triceratops - (Colorado, Montana, and Wyoming, U.S.; Alberta and Saskatchewan, Canada)
2. Arrhincoceratops - (Alberta, Canada)
3. Torosaurus - (Montana, North Dakota, South Dakota, Utah, and Wyoming, U.S.; Saskatchewan, Canada)
   
4. Monoclonius - (Montana, U.S.; Alberta, Canada)
5. Chasmosaurus - (Alberta, Canada)
   
6. Centrosaurus - (Alberta, Canada)
7. Styracosaurus - (Montana, U.S.; Alberta, Canada)
   
8. Achelousaurus - (Montana, U.S.)
9. Pentaceratops - (New Mexico, U.S.)
10. Vagaceratops - (Alberta, Canada)
    
11. Diabloceratops - (Utah, U.S.)
12. Albertaceratops - (Montana, U.S.; Alberta, Canada)
13. Einiosaurus - (Montana, U.S.)
14. Anchiceratops - (Alberta, Canada)
15. Mojoceratops - (Alberta and Saskatchewan, Canada)
16. Pachyrhinosaurus - (Alaska, U.S.; Alberta, Canada)
17. Kosmoceratops - (Utah, U.S.)
18. Medusaceratops (Montana, U.S.)
19. Utahceratops - (Utah, U.S.)

Keep in mind that the tusks seen in elephants, mammoths, walruses, and hippos, despite being superficially similar to horns, are actually greatly enlarged teeth!

Top Ten: Extinct Sea Monsters (Part 4 of 5)

7.  Archelon - Archelon is the largest sea turtle that has been discovered to date, the closest living relative that Archelon has is the "Critically Endangered" leatherback sea turtle, the largest sea turtle alive today.  Living in the Late Cretaceous Western Interior Seaway between 75-65 MYA, Archelon has been discovered in the states of South Dakota, Wyoming and Kansas. 

8.  Leedsichthys - Often cited as the largest fish known to humankind, the largest Leedsichthys had an estimated length of 72 feet, but some researchers believe that it could have grown to sizes that would rival those seen in the blue whale, the largest known animal ever to live on planet Earth.   Although Leedsichthys swam the seas only during the Jurassic Period, the group that it belonged to survived until the end of the Cretaceous Period.  Remains of this filter feeder have been uncovered in England, France, Germany, and Chile.

The Thagomizer of Stegosaurus

Stegosaurus is a very famous dinosaurs, one of the most famous, along with Triceratops and Tyrannosaurus.  All three of these dinosaurs have been found in Colorado; in fact, the first Triceratops bones were actually found in Denver, and Stegosaurus is the state dinosaur of Colorado!  Stegosaurus has also been found in Wyoming and Utah, in the Morrison Formation, as well as in Portugal.  The row of plates along its back make it very interesting looking, as do the spikes on the end of its tail, nicknamed a "thagomizer."  Holes in the vertebrae of a potential predator of Stegosaurus, Allosaurus, fit exactly with the size of one of the spikes on the tail of the Stegosaurus, showing that there was almost certainly a predator-prey relationship between the two, as was previously suspected.  Studies have shown that the tail end of Kentrosaurus, a close relative of Stegosaurus, also with a thagomizer on its tail, could have been brought around to the side of the dinosaur, potentially swatting at enemies trying to attack the Stegosaur from the side.

Finally, discoveries of articulated Stegosaurus skeletons show that the spikes were actually horizontal from the ground, as opposed to held at an angle, as you can see in the outdated and incorrect picture below.

It's an interesting word, though, isn't it: "thagomizer."  It certainly doesn't sound like a very sciency name; in fact, when I first heard it, I immediately thought it sounded like something out of one of my favorite comic strips, Calvin and Hobbes, by Bill Watterson.  Well, if you thought that as well, then you were actually surprisingly close to the mark, as the term did in fact come from a comic strip, another one of my favorites: The Far Side.

The term wasn't used scientifically until the year 1993, at the annual meeting of the Society of Vertebrate Paleontology, by the one-time Curator of Paleontology at the Denver Museum of Nature and Science Ken Carpenter.  The name has been used multiple times since then, in different mediums; books and television shows (including another personal favorite, BBC's Planet Dinosaur), as well as places such as the Smithsonian Institution and Dinosaur National Monument.  Although an informal name, it is popular, and has amusing origins.

Gary Larson created a great number of hilarious The Far Side cartoons covering all sorts of topics.  However, it seems like a large number of them featured animals, or were in some way nature related.  You will undoubtedly see a great many of them in this blog as time goes on, but here are a few other amusing dinosaur ones.
