Description of Free ResourcesDownload

Microtonal trumpets date back to the early twentieth century and there are surviving examples in the museums in Odessa and Prague.

The Microtonal Trumpet Project, which began in 1998, is a systemically researched and documented project between Donald Bousted, composer and Stephen Altoft, trumpeter.

Since 1998, the project has expanded exponentially both in the development of ideas, modified instruments and in the creation of new music.

The Microtonal Trumpet, to date, has been concerned with playing quarter-tones (24-div) and eighth-tones (48-div) on a standard 3-valve trumpet and, using a specially constructed conversion kit, quarter-tone and 19 equal divisions of the octave (19-div).

19-div valve designed for Stephen’s Bb concert trumpet

The project, as documented, is based around 24 microtonal studies by Donald Bousted.  See the publications page for details.

The Yasser Collection CD

In order to explore the 19-div tuning on the trumpet, Stephen commissioned 19 solo pieces from 17 international composers. The resulting CD, called “The Yasser Collection” can be heard on Bandcamp and is also part of our Dropbox resources. 

RASP CD

Stephen presents 11 recently written pieces in 19-division tuning.  Like the Yasser Collection before it, these pieces are diverse in orientation and international in outlook. The Liner notes are here: RASP CD Programme Notes. Order the CD from our Publications page or buy on Bandcamp.

Review from theWholeNote:
“Stephen Altoft is an explorer who draws maps of musical terrain with his trumpet. The title track, his own composition Rasp, is a slow motion expansion from a breathy hiss to an intense broken buzz. The logic of the progression is as stark as the material itself: a fearless opening statement … announcing to the listener “this is what I work with. The following tracks (especially the tenth, Studie by Manfred Stahnke) demonstrate the microtonal potential of Altoft’s remarkable customized trumpet. An extra valve and tubing permit him to divide the scale into 19 pitches without the guesswork of constantly adjusting a tuning slide mid-phrase. The effect is both comforting and disconcerting: one hears unusual pitches securely nailed instead of groped for. And that’s the point, I believe – to re-normalize the various tunings that equal temperament has hidden behind its bland reductiveness.” Max Christie
