TIME DREAMING now on Bandcamp

Hello Everyone!

Today is once again Bandcamp Friday, when all proceeds go to the artists! Bandcamp take no cut- it is their response to the pandemic.

We are using this day to launch publicly the Bandcamp version of TIME DREAMING featuring Stephen Altoft on 19-division trumpet!

Purchase here

This album saw the debut recording of the 19-division Flugelhorn, with Sarabande? by Eleni Ralli, the first piece written for Stephen’s ‘Inspired by the Baroque’ project for this instrument.

This third album featuring the 19-division trumpet deals very thoroughly with harmony: in the form of electronics, multi-tracked trumpets, duo with a malletKAT (featuring Stephen’s duo Contour partner, Lee Ferguson), and ultimately with very precisely defined 19-division three-part harmony in the title work, Time Dreaming by Donald Bousted.

Other composers featured are:

Julia Werntz (Boston)

Manfred Stahnke (Hamburg)

Eleni Ralli (Basel)

Elia Koussa (Lebanon)

Vasiliki Kourti-Papamoustou (Freiburg)

Gordon Kampe (Hamburg)

Georg Hajdu (Hamburg)

Carlos Cotallo Solares (Philadelphia)

Stephen Altoft (Freiburg)

Donald Bousted (1957-2021)

My dear friend of thirty years and longterm collaborator of twenty-five years, Donald Bousted, composer, and Artistic Director of Microtonal Projects passed away last Saturday after a second and short battle against cancer.

He founded Microtonal Projects in 2004, ran four UKMicroFests in London (having visited LA MicroFest), nine Wild dog media events in London and then founded  the EUROMicroFest with me in Germany. We travelled to South Korea together, we toured the UK and around Europe presenting the Microtonal Trumpet.

I have been co-director sind UKMicroFest 4, but performed at the events since the beginning because of our Microtonal Trumpet project.

We will try to continue what he started, always with him in our hearts and mind, remembering his vision, energy and determination, and ‘just getting on with it’.

Both Resource Folders are now hosted on my Dropbox, so I have invited those whom we still had registration records of to join the new folders, but if you find that you no longer have access, simply re-register using the registration forms on the appropriate pages.

Time Dreaming Album Now OUT!

Time Dreaming is available on most digital platforms (Spotify, Apple Music, Amazon Music etc)

This third album featuring the 19-division (of the Octave) trumpet deals very thoroughly with harmony: in the form of electronics, multi-tracked trumpets, duo with a malletKAT, and ultimately with very precisely defined 19-division three-part harmony in the title work, Time Dreaming by Donald Bousted. As 19-division tuning is a modern version of the historical third-comma meantime temperament from the early baroque, there exists a constant link to the distant past, at the same time as a glimpse towards future harmonic possibilities still to be explored.

Four of the works were premiered as part of a US Tour in 2014, playing at American Festival of Microtonal Music and Boston Microtonal Society events. Others were first played in 2019 at EUROMicroFest, TechFest Aberdeen and Festival Mikrotöne Basel. This album also sees the premiere recording of the 19-division Flugelhorn, with ‘Sarabande?’ by Eleni Ralli, the first piece written for my ‘Inspired by Baroque’ project.

Pascale Criton/Stephen Altoft

Microtonal Projects have long been associated with the french composer, Pascale Criton. She was a featured composer twice at UKMicroFest, where she was a Keynote Speaker, and has also appeared with the ‘cellist, Deborah Walker at EUROMicroFest 2017.

We are delighted to announce that Pascale is now contributing to the Microtonal Trumpet project. She and Stephen Altoft have been awarded a Virtual Partner Residency by the Goethe Institut, and are meeting online to research a work for quarter-tone trumpet and pre-recorded electronics. 

MicroFest Prague 2020

On 17th October Microtonal Projects (Stephen Altoft and Donald Bousted) took part in the online MicroFest Prague 2020. We presented a video on the subject of 19-division Harmony, focussing on the Microtonal Trumpet project and took part in an online forum. Our intention was to encourage composers who had not written in 19 before by demonstrating the broad range of approaches possible and by defining the essential harmonic elements of 19-div compared to 12-div.

All video presentations are available to watch at
