One cool thing about the Chicago Stories project is that we brought together a unique roster of instruments; some have a modern version, like the violin, and some have nothing comparable to anything in existence today. As a member of Gaudete Brass Quintet and Rook, Bill Baxtresser not only plays a slew of new music on the modern day trumpet, but he also delves into repertoire of the 16th and 17th centuries. He does this on a really unique instrument that has no sound or physical shape remotely close to anything we have today. It's called a cornetto.

And no, it's not a brand of ice cream.

This curvy cone-shaped instrument can be traced all the way back to the Medieval period, but it enjoyed the height of its popularity in the 16th and 17th centuries. It’s other aliases are the cornett, or the fun-to-say German name zink, which sounds just like it looks! 

The mouthpiece is usually made out of a kind of horn, and the body can be made of up to 10 different woods. The density and malleability of the wood can make can make it sound more bright or more mellow. The body is then wrapped with a thin layer of leather - bonus points if you can name any other wind or brass instrument wrapped in a stylish leather in the comment section below. :) 


Fun Player Fact #1:

Bill owns a cornetto that is made of the slightly softer plum wood, which gives it a dark sound. But for Chicago Stories, he'll play one that is actually a 3D print! Who knew? There's probably an app for that. :)

Fun Player Fact #2:

To accommodate facial hair, Bill makes sure to trim the top of his mustache. Another avenue to hair design?

If you know instruments, then you probably know that they fit into different categories:

  • percussion 🥁 : drums, cymbals, cowbell, etc.
  • strings (plucked, struck, bowed) 🎸🎻 : piano, guitar, violin, etc.
  • woodwind 🎷 : flute, saxophone, clarinet, etc.
  • brass 🎺 : trumpet, trombone, tuba, etc.
  • voice 🗣 : soprano, alto, bass, etc.

It could be argued that each instrument attracts a certain type of personality… but that’s another blog ;) 

One of the best features of the cornetto is that it's a hybrid - it’s not 100% woodwind or brass. To create the sound, the player buzzes their lips on the mouthpiece. In this way, it acts more like a brass instrument. At the same time, like a woodwind instrument, the cornetto has finger holes, and it has a similar fingering system as the clarinet, flute - even that recorder that we all played in elementary school.

The body is curved to allow the player to reach 3 necessary points of contact between the thumb, the little finger, and the pointer finger without over-stretching the hand, making it more easy to play. The cornettist can place the mouthpiece on either the side of the mouth or the center. Bill plays more in the center.

The result of the bras-woodwind hybrid instrument is a very chameleon-like sound, with a superb ability to blend and imitate the human voice. An especially glorious combination is that between countertenor and cornetto. :)


That cornetto was definitely not Photoshopped into this photo of countertenor and BBE Executive Director, Thomas Alaan.

This is not a video of a cornetto with countertenor, but it is still glorious, and you should still listen!


Bill particularly enjoys the expanse of colors and range that the cornetto has to offer. It can produce both a flowing, lyrical sound or the more trumpet-like “punched out” notes. (For fans of physics, the air speed Bill push through the mouthpiece has to be slow in order to get the faster sounding “punched out” notes.) It's also an incredibly flexible instrument in bending pitch. The degree of that manipulation of pitch is more or less depending on how slow or fast the music goes. The faster the music moves, the less bending that needs to happen. 


New Music for the Cornetto

As beautiful and unique as this instrument is, there are a few considerations for composers when they are writing out parts.


While all instruments have their own way to tune, they all have to be "in tune" with one another for everything to sound good. The cornettist usually tunes their instrument using the pitch “A.” However, the tricky part is that their "A" is actually higher than the "A" of the other instruments! (Again, for physics nerds, they tune an entire half step higher! The modern "A" is tuned to 440Hz, while they tune their "A" to 460Hz).

So what does that mean? That means that the part for a cornetto is written in a different key than the other instruments so that, when the pitches that come out of the cornetto, they match the rest of the ensemble. This becomes particular interesting in Amos Gillespie’s piece Solo!, which makes extensive use of the cornetto alongside five other instruments.


Another important consideration is that the cornetto is limited in the notes it can produce. Most orchestral instruments can play a chromatic scale - a scale with 12 notes. The ability to do this allows the player to play in a wide variety of keys. The cornetto, however, doesn't have all 12 notes in the chromatic scale. So, the composer is limited in the notes that it can ask the player to perform. But that's not all! Each note produces a slightly different timbre, or sound-color, so if the composer is wanting a cohesive sound from top to bottom, that produces additional challenges for the player to accommodate. So, the composer must not only be aware of what notes the cornetto can play, but also the way each sound will come out of the instrument.

Luckily, Bill's an awesome player. Because of this, and because he's able to "bend" pitches up or down, he's able to overcome a lot of these limitations. And, the bending provides more interesting colors and tones, which is to the advantage of both the performer and composer.
