The mute belt

The mute belt

Markus Stockhausen

In 1978 my father Karlheinz Stockhausen wrote the trumpet concerto "Michaels Reise um die Erde" ("Michael's journey round the world") for me. The work lasts approximately 48 minutes and is to be played from memory.

I had to be able to move freely and originally was to direct the orchestra with movements of the instrument. This requires complete freedom of movement. (Conducting with the instrument proved too difficult, however, but a new version of the same piece is to be given its first performance in Bremen on 8th May 1986 and we want to try this idea again then.)

My father asked me whether I could carry the six mutes needed for "Michael's journey" on my body, like bullets in a belt. A little later I bought some leather and made myself a mute belt. Now I use the mute belt in every performance of my father's works. You become so familiar with handling the mutes that you could pick the right one and put it back even with your eyes closed.

From the score (m. 20-29) of the 2nd “Michaels Gruss” for 8 brass, piano, 3 perc. (also called “Donnerstagsgruss”) The 3 trumpets play wawa with vowels.

Other works in which I use the mute belt are: "Aries" for C trumpet and tape with electronic music (three mutes); the "Oberlippentanz" ("Upper lip dance") for piccolo trumpet (three small mutes — I made a new belt specially for this piece); and all the other works from the opera "Donnerstag" from "Licht" in which I play trumpet ("Examen", "Festival" with the "Drachenkampf", "Vision").

I think this mute belt will soon be used by all trumpeters who make solo and even stage appearances.

Mutes, vowels and their notation

The mutes most frequently used by Karlheinz Stockhausen in his trumpet works (with the markings he has selected for them) are:

Ⓗ = Harmon (without tube)
Ⓦ = wa-wa (with tube)
Ⓕ = whisper or whispa
Ⓒ = cup
Ⓜ = Mel-o-Wah
Ⓢ = straight
Ⓟ = plunger

The sign for "mute off" is ∅.

My own mutes are:

Ⓗ, Ⓦ, Ⓕ, Ⓜ and Ⓟ from the Stone-lined series (Humes & Berg, Chicago), Ⓒ from the firm EMO (of lightweight aluminium) and a plastic straight from EMO marked weicher Spitz ("soft point"); otherwise I use metal straight mutes from Stonelined or Leblanc (Alessi Vacchiano). I mention this not by way of publicity but because my father selected these mutes from a large number of types.

As you know, some of these mutes, when used appropriately, can produce various tone colours or vowel sounds. These are Ⓦ, Ⓜ, Ⓟ and to a small extent Ⓗ as well. For these mutes Karlheinz Stockhausen uses the following notation, which corresponds with the vowel symbols of the phonetic alphabet:

[a] = completely open

[a]
[ɔ]
[o]
[u]
[u] = completely closed with the hand

[u — a], [ɔ — o] etc. = gradual transition
[a u o] etc. = sudden change

In Ⓦ and Ⓗ the opening is usually closed with the fingers of the left hand (the middle three fingers). Often the slightest movement of a single finger is enough to produce a vowel change. This is especially true in the area [u — o]. So the player must listen very carefully to be sure how the vowel really sounds. Precise production of the various vowels soon becomes easy, indeed almost subconscious.

Unfortunately good mute technique is not possible with the "German" (i.e.: rotary-valve) trumpet because it has to be held with two hands and removed from the lips for insertion and removal of mutes. You do not have a hand free for vowel sounds.

I personally will be interested to see whether a standardised mute notation will become established in the future. It could be this one.

Markus Stockhausen

Markus Stockhausen, the son of Karlheinz Stockhausen, was born in Cologne in 1957 into the up-to-the-minute world of modern music, the world with which he no doubt still feels most closely associated today. He could be described as an ambassador of his father's music; he had a part in the creation of many Stockhausen works — "Sirius", "Donnerstag" and "Samstag" from "Licht", "Michaels Reise um die Erde" and "Michaels Heimkehr" ("Michael's Return").

Stockhausen junior plays Stockhausen senior — and all over the world: in Washington, Aix-en-Provence, Tokyo, Hilversum, Houston (Texas), London, Donaueschingen, Amsterdam, Berlin and Milan.

As brilliant as he is musical, the young trumpeter soon reached the "frontiers". First it was jazz. In Germany and abroad he took part in renowned jazz festivals as a member of Key, Riot and the Rainer Brünninghaus Group; there was a big tour of Germany and in 1982 even one to South America.

But the classics were not short-changed either. While he was still at musical secondary school he was also a junior student at the Cologne College of Music and completed traditional training in trumpet and piano.

It seemed only natural that he should win the German Music Competition, complete his studies at the Karajan Academy in Berlin and be a member of the Junge Deutsche Philharmonie.

Would it be going too far to state that Markus Stockhausen could cope with any musical task required of him? His answer will be unequivocal, whether with the Haydn trumpet concerto, a free improvisation for trumpet solo, a work of his father's or a jazz rhythm.

Questions & Answers

How the Digital Edition works

What does the Digital Edition include?

The Digital Edition brings together the articles already digitized as searchable online texts—not simply as scans or PDF files—along with their original illustrations, notes, authorship, issue information, and available translations. Related-article suggestions currently include only this digitized material.

Are the digital articles identical to the originals?

We preserve the original text, language, illustrations, captions, footnotes, and editorial context as faithfully as possible. The presentation is adapted for comfortable online reading, and obvious transcription or scanning errors may be corrected. The substance and character of the published article remain unchanged.

Which languages are available?

Brass Bulletin was published in English, French, and German throughout its history. Italian and Spanish translations were added from issue No. 60 onward.

On the Italian and Spanish sites, articles from issues 1–59 are therefore shown in English by default.

How often are new articles added?

New articles are added almost daily, with approximately one complete issue digitized each week. The pace may vary depending on the preparation, image work, and editorial checking required.

Why aren’t all articles available digitally?

The complete Brass Bulletin collection contains 1,246 articles published between 1971 and 2003. The full index is already available online, allowing readers to discover every article in the collection, including those whose complete text has not yet been digitized.

Digitization began in February 2026. Each article is carefully prepared for online reading, checked, and connected to its issue, authors, subjects, and illustrations. At the current pace of digitization, the complete collection is expected to be available online by February 2028.

Why do some references mention articles that are not available yet?

References in the original articles are preserved even when the material they point to has not yet been digitized. This keeps the historical and editorial record intact. As more issues are added to the Digital Edition, an increasing number of these references will lead to articles that can be read online.

Can I suggest an article or report a transcription error?

Yes. If there is an article you would particularly like to see digitized, or if you notice a possible transcription error or missing detail, please contact us. Reader feedback helps us improve the Digital Edition and prioritize useful connections within the archive.

How can I support Brass Bulletin?

Your support helps fund the preparation, verification, and online publication of the complete collection.
